Condition

Some customers may comment that they are unable to use Wi-Fi, access embedded apps and personalization features in the radio.

The Emergency (e-Call) function is still operational.

Upon sale of the vehicle, the module is expected to obtain a “Local” profile and cellular number for use.

The module could lock up during the transition from the factory default “Bootstrap” profile to “Local” profile. In rare instances the module is unable to recover nor revert to the “Bootstrap” profile.

An over the air (OTA) fix is being released through the local cellular network.

If the OTA update is unsuccessful due to the module already being locked up, then this service bulletin will need to be applied to remedy the customer concerns.

 

Cause

This condition may be caused by a software anomaly with the eSIM operating system.

 

Correction:

Replace the Communication Interface Module / Telematic Control Module.

Reprogramming

GM Diagnostic/Programming (TIS2Web)

 

Approved J2534 Device with TIS2WEB can reprogram 1996 and later All GM Modules.

To obtain the latest electronic controller calibration information for your vehicle, go to https://tis2web.service.gm.com/tis2web and enter the vehicle's 17 character Vehicle Identification Number (VIN) and select 'Get CAL ID’.

You can then compare the latest part number with the actual number installed on the vehicle to determine if a reprogram is needed.

The Service Programming System (SPS) application is part of the TIS2Web system. To program an ECU, the SPS application must communicate with the vehicle control modules using the proper J2534 programming interface tool.

The following are the supported interface tools:

The Tech 2 supports model years 1996 and beyond. With the addition of the CAN Diagnostic Interface (CANdi) module, Tech 2 is fully backward compatible with current Tech 2 functionality and operates transparently when diagnosing non-CAN-equipped vehicles.

Servicing the next generation Global A vehicles will require the diagnostic software, GDS2, Global Diagnostic System 2 running on a local PC device while the MDI is connected to the vehicle. The GM MDI is the Global Diagnostic tool for future vehicles starting with Global A vehicles.

The GM MDI was introduced in the fall of 2007 for Pass-Thru programming and offers faster programming speed. It can be used to perform Pass-Thru programming on all vehicles built since 1996 and into the future. Click here to view a list of GDS supported vehicles.
