June 2007 Archives

The Techline team appreciates when users take a moment to share with us their feedback regarding our websites. Our goal is to quickly provide GM technicians the information they need to service our vehicles.

The following provides an overview for submitting feedback to Techline regarding these applications.

- Service Information (SI), including the Service Manual, Bulletins/Campaigns, and the GM Labor Time Guide.

- TIS2WEB, including Tech 2 Diagnostics and the Service Programming System (SPS).

Your feedback helps us keep the applications working properly, helps ensure that the applications are user-friendly, and helps ensure that the information provided is accurate.

To get started, you must first select SI or TIS2WEB from the GM DealerWorld home page (GM infoNET in Canada).

TIP: If you wish to provide feedback about the DealerWorld site, use the feedback button located at the top right of the main page.

Service Information (SI)

TIP: SI is now available in both English and Spanish.

There are several ways to access the SI feedback form. Depending on where the form is accessed from, the form will be sent to one of three mailboxes for review and response. The three mailboxes are Service Manual, Labor Time Guide, and Bulletins/Campaigns.

First, on the SI home page, you can click on the Feedback link (fifth icon on the list) (fig. 4). From this page, the form will automatically default to the Service Manual mailbox.

Second, on every service document in SI, there is a Feedback button in the upper right corner (fig. 5). Click on this button to open the Feedback form.

Once the feedback form is open, fill in all of the relevant blanks, including your name, dealer name, dealer code, etc.

TIP: Be sure to include your email address and phone number, because someone from the SI team may want to contact you for further discussion.

To submit a problem, fill in the requested information. Be as thorough as you can be when giving a detailed description of the problem.

TIP: If you have already "built" a vehicle, and are looking at a service document when you click the Feedback button, the feedback form will automatically fill in the vehicle you're working on and the document ID number.

To submit a suggestion, fill in the box provided, using your own words to give a detailed description of your suggestion.

Once you have submitted your feedback, SI will send an automated receipt to let you know it has been received.

TIS2WEB

To open the TIS2WEB feedback form, click on the Feedback icon in the toolbar. It's the second icon from the top right of the page.

You can choose the type of feedback you wish to comment on, using the pulldown menu in the upper left corner of the page.

The Online Questionnaire is the default form, and is the one you'll probably use the most.

Fill in the spaces provided to comment on the content of the website, the timing of the content (is it on time to help your customer?) and your overall satisfaction.

To provide specific comments or to offer specific critiques, use the comment box provided. Type your comments into the box in your own words. Be as thorough as you can, and provide as much detail as possible.

It's recommended, but optional, that you fill in the contact information at the bottom of the form. This is necessary if you want to receive a response. Your response will be sent to you by email. Typically, allow 30 days or less for a response if your issue is "mainstream." Allow more time if your issue will require extensive research.

A recent bulletin 05-08-67-014 update provides general guidelines to noise issues with the panoramic sunroof in the Pontiac G6 (fig. 14). Here are highlights of two of the conditions described in the bulletin.

US dealers, also refer to Tech Assist course 50250.17T1 Multi-Panel Panoramic Roof Adjustments for more information.

Creak/Snap/Pop Noise

This condition occurs while driving over bumps and comes from the sunroof module, and is usually caused by roof interaction with the fasteners.

TIP: The bulletin specifies slightly different repairs depending on whether the vehicle was built before or after January 1, 2006, when mylar washers were added to production.
For vehicles without the washers, the bulletin explains how to install them.

For all vehicles, lubricate the 10 locations of the mylar washers using GM Super Lube
(p/n 12346241) (fig. 15).

TIP: Use Super Lube only. No fastener adjustments are necessary unless noise is still present after lubrication.

TIP: It is necessary to lower the headliner before spraying the lubricant. Follow the bulletin procedure to propely cover all interior trim to avoid damage from the lubrication process.

Wind Noise

It is important to understand where the wind noise is coming from.

Apply masking tape to the outside of the roof in the suspected area, then test drive the vehicle. After identifying the location, refer to the bulletin for the recommended repairs.

From the front -- could be leak from roof to seal or seal to front glass panel.

Roof to seal -- adjust front mounting bolts

Glass to seal -- adjust front glass panel

From sides -- adjust side mounting bolts

From corners -- adjust corner mounting bolts

Refer to the bulletin for additional details on repair procedures and updated module seal and cross car glass panel foam (fig. 16) part information.

TIP: Some leakage is normal at the T-joints by design.

TIP: Do not order an entire module to obtain the updated seal.

TIP: Call Webasto Sunroof at 1.800.995.5911 for persistent issues before replacing the module.

This information applies to the 2007 Saturn Outlook and GMC Acadia. Details will be covered in an upcoming bulletin. Here are highlights.

Towing with Vehicles without Trailer Provisions (RPO V92)

These vehicles can tow a maximum trailer weight of 2,000 lb. (907 kg).

These vehicles must be modified by installing a new underhood bussed electrical center (UBEC) to provide full functionality for 4 circuits: ground, tail lamps, RH and LH stop/turn lamps.

To find the original part number, remove the UBEC and look at the side of the UBEC.

TIP: This UBEC replacement should be performed only for customers who perform trailer towing.

Towing with Vehicles with Trailer Provisions (RPO V92)

These vehicles can tow a maximum trailer weight of 4,500 lb. (2,041 kg) (fig. 17).

It is necessary to modify the wiring harness at the Body Control Module (BCM).

Disconnect the X7 connector from the BCM and remove terminal pin 3 (dark blue wire, 38 circuit). Re-connect the X7 connector.

Splice this wire into the wire at BCM connector X6, pin 2 (light green wire, 24 circuit).

Recreational Vehicle Towing (Dinghy Towing)

Recreational vehicle towing means towing the vehicle behind another vehicle, such as behind a motorhome.

Dinghy towing -- towing the vehicle with all four wheels on the ground

Dolly towing -- towing the vehicle with two wheels on the ground and two wheels on a dolly

TIP: To avoid battery rundown while towing, disconnect the battery before towing. 

TIP: Vehicles with a 6-speed automatic transmission that are dinghy towed must be started and run for a minimum of five minutes at the beginning of each day and at each fuel stop.

* Unlimited miles at 65 mph (105 km/h). To avoid vehicle damage, never exceed 65 mph (105 km/h). The repairs would not be covered by the warranty.

IMPORTANT: The owner must observe all procedural steps in the bulletin when dinghy towing.

Before starting, do the following steps:

- Secure to tow vehicle.

- Ignition OFF.

- Set parking brake.

- Ignition to ACCESSORY.

- Shift transmission to NEUTRAL (N).

- Disconnect negative battery cable. Release parking brake.

At destination, do the following steps

- Set parking brake.

- Reconnect negative battery cable.

- Ignition OFF

- Remove key from ignition.

Some owners of a 2007 Silverado or GMC Sierra may comment on the openings under the bed rails near the stake pockets (fig. 18). While the openings on the new Silverado and Sierra are more visible, the Classic Silverado and Sierra had similar openings around the stake pockets. The openings are required for the unique forming process of the new pickup box side inner stamping. The new design has equivalent performance for dust and moisture intrusion when compared to the previous design.

TIP: The pickup box is not designed to be sealed completely from dust or moisture intrusion.

The owner of a 2003-07 Saab 9-3 may comment on wet carpet on the right side floor. An area under the bulkhead cover on the passenger side may have had sealer improperly installed.

This condition could cause a leak at the A-pillar that could allow water into the front foot well and rear floor. The leak path is down the A-pillar to the front floor and then rearward underneath the carpet and insulation collecting in the rear floor area, which is lower than the front.

Check the right rear corner of the engine compartment under the bulkhead cover for missing sealant (fig. 19). Also check the A-pillar behind the glove box from the passenger foot well side for missing sealant (fig. 20).

Observe this reminder when performing the procedure covered in the March 2007 TechLink article on the Lower Timing Gear Tensioner Holding Tool Tips.

Carefully follow the repair instructions outlined in Bulletin 06-06-01-17C to properly use the Lower Timing Gear Tensioner Holding Tool (EN48464) (fig. 22). Failure to properly insert and secure the holding tool as instructed in the bulletin may result in a ratchet out movement of the timing chain tensioner and the need to perform additional repair steps not covered by the warranty repair time.
