Tire Pressure Sensor Learn

TIRE PRESSURE SENSOR LEARN

TOOLS REQUIRED: J 41760 Tire Pressure Sensor Activating Tool

The tire pressure monitor (TPM) system uses the remote control door lock receiver (RCDLR), body control module (BCM), driver information center (DIC), 4 radio frequency transmitting pressure sensors in each wheel/tire assembly, and the serial data circuit to perform the sensor learn mode functions. The sensor learn procedure must be performed after a tire rotation, or after a tire pressure sensor is replaced. Once the learn mode has been enabled, each of the sensors unique identification (Id) codes can be learned into the RCDLR's memory. When a magnet is held close to the sensor, an internal switch is closed forcing the sensor to transmit. After the RCDLR has received a sensor transmission, it sends a serial data message to the BCM to sound a horn chirp indicating the sensor has transmitted it's Id code and the RCDLR has learned it. The RCDLR must learn each sensor's Id code in the proper sequence in order to determine sensor location. The learn mode will cancel if more than 1 minute passes and no sensors have been learned, or if more than 5 minutes pass for the entire procedure. If the learn mode is cancelled before any sensor Id is learned, the RCDLR will remember all previously stored sensor Ids and their locations. As soon as the RCDLR learns the first sensor Id, all previously stored Ids are erased from the RCDLRs memory.

1. Turn "ON" the ignition, with the engine "OFF".
2. Press the "DIC RESET" button in order to clear any warning messages.
3. Press and release the "OPTIONS" button until the display is blank.
4. Press and hold the "RESET" button for 3 seconds.
5. Press and release the "OPTIONS" button until "TIRE TRAINING" is displayed.

IMPORTANT: If a horn chirp does not sound after 15 seconds, remove then reinstall the sensor activating tool.

6. Starting with the left front sensor, hold the J 41760 over the left front valve stem until a horn chirp sounds.
7. After the horn chirp sounds, proceed as in step 6 for the next 3 sensors in the following order:
a. Right front
b. Right rear
c. Left rear
8. Turn the ignition "OFF" to exit the learn mode.
