Tire Pressure Monitor (TPM) Sensors for GM Accessory and Aftermarket Wheels/Tires

Some customers may elect to purchase GM Accessory wheels/tires or aftermarket wheels/tires that require the proper tire pressure sensors to be installed in each wheel and tire assembly.

The 2007 model year full-size trucks require unique tire pressure sensors which are not interchangeable with past model year sensors or with other GM models not listed above.

Installing the wrong tire pressure sensors in any road wheel will cause a "Service Tire Pressure" message and one or more DTCs to set.

All 2007 models listed above were shipped from the assembly plant(s) with the proper tire pressure sensors installed in each wheel/tire assembly and the sensors were properly programmed to the vehicle. Each sensor has its own unique ID code that can be displayed on the J-46079 special tool.

Part numbers of compatible TPM sensors are as follows:

Dealers who experience TPM problems after the installation of GM accessory wheels/tires or aftermarket wheels/tires should verify that the tire pressure sensors are the correct part number sensor for the vehicle and can communicate with the J-46079.

If the J-46079 displays the individual tire pressure sensor IDs, but the vehicle will not learn the sensors, dealers should use the "simulate" feature on the J-46079. In the "simulate" mode, the J-46079 transmits four unique "test" IDs to the vehicle. This allows the user to test the vehicle's ability to learn tire pressure sensors. The "test " IDs sent by the tool are for test purposes only. Valid sensor IDs must be pre-programmed into the vehicle after the "simulate" mode has been used.

Testing the Vehicle's Ability to Learn Using the "Simulate" Feature on the J-46079

1. Turn ON the ignition with the engine OFF.
2. Apply the parking brake.

Important: If the learn module cannot be enabled, ensure that the TPM system is enabled in the RCDLR. Refer to Control Module Setup in SI.

Using the driver information center (DIC), press the vehicle information button until the RELEARN TIRE POSITIONS message displays. If the vehicle does not have the DIC buttons, press the trip odometer reset stem located on the instrument panel cluster until the RELEARN TIRE POSITIONS message displays.
If the vehicle has the DIC buttons, press the set/reset button. The horn will sound twice to indicate the TPMs receiver is ready, and the TIRE LEARNING ACTIVE message will display. If the vehicle does not have the DIC buttons, press and hold the trip odometer reset stem until the horn chirps twice and the TIRE LEARNING ACTIVE message is displayed.
Alternate method: Lower the driver's window and simultaneously press the keyless entry transmitters lock and unlock buttons until a horn chirp sounds. A horn chirp will sound indicating the learn mode has been enabled.
3. Place the J-46079 in the "simulate" mode. Follow the tool prompts and program all four tire positions into the vehicle. A horn single chirp will follow the programming for each position. A double horn chirp will indicate the learning sequence has been successful. When you have successfully used the "simulate" mode, the tool will display the simulated sensor IDs and tire pressure for each tire position.

Tip
The tire pressures displayed by the tool will not agree with the tire pressures displayed by the DIC. This is an anomaly with the tool software and does not indicate a problem. A double horn chirp after the fourth tire is programmed indicates that the vehicle can learn TPM sensors.

Warranty Information

Warranty claims should not be submitted for incorrect tire pressure sensors found in GM Accessory wheel/tire assemblies. Incorrect sensors assembled into GM Accessory wheels/tires or aftermarket wheels/tires by GM dealers or other sources are the responsibility of the installer or vehicle owner.
