The all-new instrument panel features an 8-inch Chevrolet MyLink touch screen with Bluetooth® streaming audio, cell phone connectivity, and voice recognition. Applications requiring a USB connection are not compatible.


The revised front seats provide increased comfort and support for officers wearing a utility belt. Front hip room has increased to 57.5 in. from 56.7 in. The front seats have 4-way power seat adjusters and power lumbar adjustment.


The door lock button has been relocated to the top-rear of the door. Pull the interior door handle once to unlock and pull it again to open the door. In addition, standard trunk release buttons are on both front door interior panels.


The auxiliary battery, located in the trunk, has a higher capacity 700 CCA to power accessory equipment. (Fig. 4)

To deliver enhanced performance, electric power steering is standard. The thicker front struts (32 mm instead of 30 mm) and front stabilizer bar (26 mm instead of 24 mm) also provide improved handling.


Special Features


An auxiliary 110-amp ignition and main power supply wiring harness is located under the lower right side of the instrument panel. One 50-amp battery power circuit and two 30-amp relay controlled circuits are in a five foot coil provided for customer connection. The harness includes signal circuits for ignition power (Hot in Start/Run and Accessory/Run), vehicle radio mute, vehicle speed signal and park-enable.


Surveillance Mode is standard on the Caprice PPV. The Surveillance Mode circuit is terminated in cavity 1 of the 16 cavity upfitter connector P277, located at the passenger-side front of the equipment mounting platform.


When Surveillance Mode is activated by applying a ground to the White/Violet wire in cavity 1, all automatic lighting functions are suppressed. All manually operating lighting controls remain functional. If equipped with RPO VVS, Daytime Running Lamps and Automatic Headlamps Disabled, exterior lights are controlled manually. Surveillance Mode suppresses all of the following items:

• Radio display is off (audio remains on)

• Headlamps and tail lamps are off

• Dome lamps are disabled (inoperative at the lamp switches)

• All interior lighting is off

• Remote Lock/Unlock audible/visual functions are off


RPO 7Y6, Inoperative Dome/Courtesy Lamps, has been deleted for 2014 and replaced by a switch in the front dome lamp assembly. Activate the switch to have the dome lamps remain off when any door is opened, the vehicle is unlocked, or the key is removed from the ignition switch.


The Caprice PPV does not come equipped with OnStar.


Transport Mode


All 2014 model year vehicles leave the assembly plant with Transport Mode active to save battery power. The Driver Information Center (DIC) will display Transport Mode On when enabled.


TIP: The driver’s express power window learn procedure may need to be performed after turning off Transport Mode. When in Transport Mode, the remote function will be inoperative. As the Remote Keyless Entry will not allow remote unlocking of the vehicle, the vehicle will need to be unlocked with the mechanical key.


To disable Transport Mode:

1. Turn on the hazard flashers.

2. Apply the brake pedal.

3. Turn the ignition key to the Start position and hold for 15 seconds; continue to depress the brake pedal.

4. Transport Mode Off will display in the DIC when disabled.




The 2014 Caprice PPV uses the Global A electrical architecture, which requires the use of the GDS 2 for diagnostics.


For programming, the vehicle may be found under the Chevrolet Holden heading.




Two keys with Remote Keyless Entry functionality are provided for the Caprice PPV. Options 6E3 or 6E4 are available for police departments requiring a single key for the entire fleet. These common key options provide a single key with a specific code that is common to the door locks and ignition for all the vehicles in the vehicle fleet. They are not compatible with Impala, Tahoe and the previous Caprice police vehicles.


TIP: If the engine is running or the key is left in the ignition with the engine off, the Remote Keyless Entry function of a second key cannot be used to operate the door locks.


Pre-Delivery Inspection


The factory-installed rear disc brake rotor protection covers (Fig. 5) must be removed during the PDI. With the vehicle on a hoist, rotate the wheel while at the same time pulling the torn end of the cover away from the disc brake rotor and wheel. Ensure that all material is removed and repeat for the other side.

Weather Conditions’ Effect on High-Performance Brake Components

Some 2012–2015 Camaro SS, Camaro ZL1; 2013–2016 ATS; 2014–2016 CTS (VIN A); 2014–2015 Camaro Z/28, Caprice PPV, Corvette, and SS models may be hard to move after the vehicle has been parked for a period of time. A crunch sound right before the vehicle starts to move may be heard.

Depending on how long the vehicle has been parked, the weather conditions in which the vehicle was parked, and how recently the vehicle has been washed, the condition may be a simple noise when the vehicle first moves or, at the extreme, the vehicle cannot be moved out of the parking space.

This condition may be due to the brake pads freezing to the vehicle’s rotors. Do not replace any brake components for this condition.

High performance brake components (Fig. 11) have a tendency to lightly bind, often noted as resistance, and then lightly clunk when attempting to move the vehicle forward or rearward after a cold soak. This is usually noticed after parking, when the brakes have been wet, such as when driving in the rain or just after a car wash. This is expected of high performance brakes with high friction pads and does not affect the operation or performance of the brakes.

2015 Chevrolet Camaro Z/28

Fig 11

If a residual roughness is felt when braking, it can be easily cleaned by applying the brakes several times until the roughness is gone. If washing the vehicle prior to long-term storage, it is recommended that the vehicle be driven and the brakes applied several times before storing the vehicle.

Front Door Window Jamming

The driver or passenger front door window may become jammed and will not rise above half-way on some 2011-2014 Caprice PPV, SS, and 2008-2009 G8 models. The front edge of the door glass may become dislodged from the front window run channel and seal. This usually occurs when the front door has been slammed closed with the window fully lowered.


TIP: Once the glass has become dislodged from the front window run channel and seal, the metal channel will likely be distorted and need to be replaced. The seal normally does not require replacement.


Add Foam Spacer


When replacing the window front run channel (Fig. 5), it’s necessary to add a foam spacer (part number 92289653) to both front doors.


To add the foam spacer, remove the front window run channel from the door.


F05 window run channel

Fig 5


Fit the foam spacer to the bottom outboard side of the new replacement front window run channel. Ensure the spacer is centered, glue side down, on the channel and positioned 5 mm (0.20 in.) from the bottom end. (Fig. 6)


F06 window spacer 5mm

Fig 6


With the new front window run channel in the door, the foam spacer (Fig. 7, A) should touch against the side intrusion beam. (Fig. 7, B)


F07 window side beam

Fig 7


After properly securing the run channel and window glass on the affected door, add the foam spacer to the other front door between the front window run channel and the door side intrusion beam.


For additional information, refer to Bulletin #12-08-64-004A.

The high feature V6 engine family features a camshaft drive system that consists of a primary timing drive chain driven by the crankshaft sprocket. The primary timing drive chain drives two intermediate drive shaft sprockets. Each intermediate drive shaft sprocket drives separate secondary timing drive chains, which drive the respective cylinder head’s intake and exhaust camshaft position actuators.


When timing the high feature V6, refer to the latest version of #PIP4384 for valuable supplemental information. It contains several pictures and other information that may be helpful when timing the engine. (Fig. 11) Consult the appropriate Service Information for complete timing procedure information.

 F11 2091921

Fig 11


TIP: For additional information, view video 10208.01D, January 2008 Emerging Issues, from the GM training website (U.S. only). In Canada, view Tech Assist video 16038.01W, Timing the High Feature 3.6L V6 Engine, on the training website and a related video in the GM GlobalConnect Service Library under Technician Resources >TAC Talk Video Help.


Before beginning the timing procedure, keep these items in mind:


• In a front-wheel-drive vehicle, it may be easier to remove the engine before beginning.

• When removing the front cover, be sure to remove the belt tensioner and all the bolts. Damage may occur to the block if this procedure is not followed.

• When removing the front cover, do not pry against or strike the cam actuators. This will cause damage to the reluctor or actuator.

• Intake cam actuators have marks on them for the Right Bank (R) and the Left Bank (L). They must be positioned respectively.

• Be sure to note the orientation of the injector wiring harness. The harness with connector should come out on the front side of the engine. If installed backwards it will cause misfires and/or fuel trim DTCs.

• 4-screw Delphi cam actuators and 5-screw Aisin cam actuators are interchangeable, but require the correct shim behind them when applicable. 4-screw Delphi actuators use a 0.043 in. shim and the 5-screw Aisin actuators use a 0.063 in. shim.

The 2014 Chevrolet SS


The Rear-Wheel-Drive Performance Sedan Returns



Fig 1


The 2014 Chevrolet SS, Chevrolet’s first V8 rear-wheel-drive performance sedan since 1996, is designed to deliver performance on the street and on the track.


Sharing its underpinnings with the Camaro, Caprice Police Patrol Vehicle and Holden’s VF Commodore, the SS benefits from a proven, race-tested, global rear-wheel drive architecture.


The SS features a high performance version of the legendary Chevrolet 6.2L V8 small block engine and a 6-speed automatic transmission equipped with TapShift®.


Here’s a closer look at the new SS.




V8 Engine


The all-aluminum small-block 6.2L V8 engine (RPO LS3) produces 415 horsepower (310 kW) @ 5900 rpm and 415 lb.-ft. of torque (563 Nm) @ 4600 rpm, which propels the SS to a 0-60 acceleration time of about five seconds.


dexos 1™ SAE 5W-30 is the recommended viscosity grade for the 6.2L engine. Do not use other viscosity grade oils such as SAE 10W-30, 10W-40, or 20W-50.


Automatic Transmission


The 6-speed automatic transmission includes TapShift controls located on both the shift knob and the steering wheel. It includes a transmission oil cooler. The engine’s torque is channeled to the rear axle, which has a 3.27 ratio for a great feeling of performance.


Sport Shift mode – can be selected for maximum responsiveness. The transmission will delay upshifts and allow earlier downshifts. In addition, the transmission can sense enthusiastic driving, at which point it may delay upshifting and downshift earlier when braking.


Active Select (A/S) mode – allows gears to be selected manually. It can also provide engine braking by selecting the appropriate lower gear on a steep downhill grade.




4-Wheel Independent Suspension


The SS is equipped with 4-wheel independent Sport-Tuned suspension (FE3).


The front suspension is a multi-link MacPherson strut setup with a direct-acting stabilizer bar and progressive-rate coil springs. Camber, caster and toe are fully adjustable. A hydraulically damped bushing is used on the forward end of the tension link for improved ride isolation.


The rear suspension is a multi-link independent system with progressive-rate coil springs over shocks; decoupled stabilizer bar and fully adjustable camber and toe. High lateral stiffness for handling is provided by three lateral ball joints per side with improved longitudinal compliance. A rubber isolated suspension frame isolates the body from road imperfections and drivetrain vibrations.


Electric Power Steering


The Electric Power Steering (EPS) system uses a forward-mounted steering rack. The variable-effort electric power-assisted rack-and-pinion steering is calibrated to detect constant driver steering wheel load due to factors such as road camber and crosswind. The system will compensate to reduce steering effort to a more neutral level and lessen potential driver fatigue.


Brembo Brakes


Standard front Brembo aluminum 4-piston calipers operate on ventilated 14-inch (355-mm) two-piece rotors. (Fig. 3) Solid 12.7-inch (324-mm) rotors are used at the rear. The Brembo aluminum brake calipers provide increased stiffness to reduce fluid displacement and caliper deformation without adding weight, reducing brake wear and providing superior braking performance.


2014 Chevrolet SS

Fig 3


Electronic Brake Force Distribution optimizes control of rear brake pressure on all road surfaces and under all vehicle loading conditions.


Electronic Brake Assist senses how hard and fast a driver depresses the brake pedal and gives extra braking assistance, if required.


High-Performance Tires


The SS uses ultra-high-performance summer-only Bridgestone tires — 245/40ZR19 on the front, mounted on 19 x 8.5-inch polished forged aluminum alloy wheels and 275/35ZR19 on the rear, mounted on 19 x 9-inch polished forged aluminum alloy wheels. The different size front and rear tires should not be rotated front to rear. Rotate the tires in a side-to-side rotation pattern only.


TIP: Summer performance tires should not be used for driving in winter conditions. Doing so will adversely affect safety and performance.


Depending on equipment, the SS may come with a full size 245/40ZR19 spare tire that is the size that comes as original equipment on the front of the vehicle. If a flat tire occurs on the rear of the vehicle and the spare tire is installed, a 275/35ZR19 tire must be installed on the rear of the vehicle as soon as possible.




MyLink Infotainment System


The Chevrolet MyLink infotainment system is standard on the SS and is accessed via an 8-inch (203 mm) diagonal color touch screen housed in the center stack. (Fig. 4) The system features a Bose® 220-watt, 9-speaker premium sound system including subwoofers, a CD player and navigation.



Fig 4


Standard Automatic Parking Assist


SS is the first Chevrolet to offer Automatic Parking Assist, which provides hands-free parking help. The system uses an ultrasonic sensing system to detect the width and depth of either parallel or reverse right-angle parking spaces. While the driver controls the throttle, transmission and brake, Automatic Parking Assist controls the steering input necessary to park the vehicle.


When activated, the system searches for parking spaces to the right of the vehicle. To search for a parking space to the left, turn on the left turn signal.


If the vehicle is in R (Reverse), but does not steer into the expected space, the system may be maneuvering the vehicle into a previously detected space.




Global Diagnostic System 2 (GDS 2)


The 2014 SS uses GM’s Global A electrical architecture, which requires the use of the Global Diagnostic System 2 (GDS 2) software and the Multiple Diagnostic Interface (MDI) module.


Navigation Path to Select the Vehicle When Using SPS to Reprogram a Control Module


Because the Chevrolet SS is built in Australia, the navigation path used to select the vehicle when using SPS to reprogram a control module is slightly different. Follow these steps:


1. In the Service Programming System – Validate/Select Vehicle Data – Salesmake screen, select the drop down menu.

2. Scroll down the menu until Chevrolet Holden appears.

Forward Collision Alert is standard and uses a digital camera to help drivers avoid front-end collisions. It is a warning system only and does not apply the brakes.


The high-resolution digital camera is mounted on the windshield, ahead of the rear view mirror. The system looks for vehicles ahead and uses the vehicle’s Head-Up Display (HUD) to warn drivers if they are following another vehicle too closely. The system detects vehicles within a distance of approximately 197 ft (60 m) and operates at speeds above 25 mph (40 km/h).


Lane Departure Warning is a camera-based lane detection system that uses a camera sensor mounted on the windshield ahead of the rearview mirror to detect the lane markings. It warns the driver of unintentional lane departures if the vehicle is crossing a lane without using a turn signal.


Side Blind Zone Alert uses radar sensors on both sides of the vehicle to look for other vehicles in the side blind zone areas and indicates their presence with LED-lit symbols in the outside mirrors.


Rear Cross Traffic Alert uses the same sensors as the Side Blind Zone Alert system to warn drivers of approaching vehicles when backing out of a parking spot, including angled parking. Visual and audible alerts are triggered if moving vehicles are detected.




The 2014 SS was neither designed nor intended to be towed with any of its wheels on the ground. If the vehicle must be towed, use a flatbed car carrier.


There are two oval-shaped slots under the front of the vehicle that should be used to move a disabled vehicle. To hook to the vehicle, use only these slots. The slots can be accessed through the splash shield. Use an appropriate size T-hook for the slot. Use the proper nylon strap harnesses around the tires to secure the vehicle on the flatbed carrier.




The factory-installed shipping spacers in the front coil springs provide additional clearance during vehicle transportation and MUST be removed when performing the PDI. (Fig. 5) With the vehicle on a hoist, remove the shipping spacer and repeat for the other side.

The factory-installed rear disc brake rotor protection covers also MUST be removed when performing the PDI. With the vehicle on a hoist, rotate the wheel while at the same time pulling the torn end of the cover away from the disc brake rotor and wheel. Ensure that all material is removed and repeat for the other side.


In addition, check the tire air pressure during PDI. The pressures are set higher for shipping. The tires pressure should be set at 36 lbs. Refer to the Tire and Loading Information Label near the driver’s door latch.

Fluid in Spark Plug Tubes

A Check Engine light may be illuminated with misfire DTCs set, or a possible oil or coolant leak may be found, on some 2010-2013 Enclave, LaCrosse, CTS, SRX, Camaro, Equinox, Traverse, Acadia, Terrain; 2012-2013 Caprice PPV, Captiva, Impala; 2013 ATS and XTS models equipped with 3.0L and 3.6L (RPOs LF1, LFW, LLT, LFX) HFV6 engines. (Fig. 10)

On inspection, coolant or oil may be found in a spark plug tube. Determine if the oil or coolant is coming from the spark plug tube and not leaking into it from above. If the spark plug tube is leaking, replace the cylinder head, spark plug and coil.


Porous spots in the head created during manufacturing cause the leak. The spark plug tubes are permanently sealed into the head and are not replaceable.


If a cylinder head is replaced for this condition, mark the faulty spark plug tube before sending the head in for warranty or core so GM Engineering or the re-manufacturing facility can identify it.
