Recently, TIS 2 Web made available two new features:
- The ability to use the Tech 2 as a J2534 service programming device.
- Clear DTC selection at the end of a programming event.
TIP: SAE J2534 is a recommended industry standard for pass-thru programming.
J2534 Tech 2 pass-thru programming is the successor to Legacy pass-thru programming. This new programming method provides a number of benefits such as improved programming speed and reliability. GM Service Operations recommends using this programming method for all SPS procedures.
To utilize the J2534 pass-thru feature, follow the simple installation instructions when prompted.
The Clear All DTC function is available at the end of a programming event at the Final Instructions screen. This function eliminates the need to manually clear DTCs for each controller with the Tech 2. A reminder message is displayed in the Preparing for Communications screen before the programming process is started.
TIP: Because all DTC and Freeze Frame data will be cleared, it is recommended to record any appropriate DTC information before making the selection.
The Clear DTC function is limited to Class 2 and GMLAN vehicle protocols. Vehicles with other protocols or those combined with other protocols still require DTCs to be cleared manually. This will typically be done as part of the module setup procedure. It is good practice to confirm all codes are cleared using the Tech 2 after each programming event or module setup. The function is available only when at least one Class 2 or GMLAN controller is recognized on the vehicle.
