Reseting the C5

TPM Sensor Programming
The Tire Pressure Monitor (TPM) system interfaces with the
Instrument Panel Cluster (IPC) through the serial data line. Once the program mode is
accessed through the IPC, each sensors unique identification code can be programmed into
the receiver's memory.
Each sensor must transmit the unique code in the proper
sequence. A magnet must be held close to the sensor in order to force the sensor to
transmit the identification code. The IPC will display a message as each sensor is
programmed, and when to proceed to the next sensor for programming. The receiver also
sends a message to the BCM to sound the horn one time, indicating that the sensor properly
transmitted an identification code. If the programming sequence is cancelled before any
sensor is programmed, or if the vehicle's battery is disconnected, the receiver will
remember all current identification codes. As soon as the receiver learns the first sensor
code, all previously stored codes are erased from the receivers memory.

Important: Make sure the vehicle has been stationary for at least 2 minutes
before attempting to program the TPM sensors.
1. Turn the ignition to ON.
2. Press the RESET button in order to clear any IPC display
3. Press and release the OPTIONS button on the DIC to
scroll through the display options until the IPC display is blank.
4. Press and hold the DIC RESET button for 3 seconds.
5. Press the OPTIONS button again until the TIRE TRAINING
Notice: If the TIRE TRAINING message cannot be displayed, and the IPC is
functioning properly, check if the BCM is configured with the correct RPO codes. Refer to
BCM Programming/RPO configuration.
6. Press the RESET button until the IPC LEARN L FRONT TIRE
message appears in order to begin the programming sequence.
7. Install the J 41760 Tire Pressure Monitor (TPM) System
Programming Tool over the left front valve stem.
8. The horn will sound, indicating the left front TPM
sensor is programmed.
Important: If the horn does not sound after 15 seconds, remove then reinstall
the TPM sensor programming tool. This procedure may have to be attempted up to three times
in some instances.
When the horn sounds, proceed to program the next TPM
sensor in the following order as directed by the IPC messages
- LEARN R FRONT TIRE
- LEARN R REAR TIRE
- LEARN L REAR TIRE
1. The programming mode will be cancelled if any of the
following conditions are met
- The program mode is exited through the DIC.
- The ignition is turned to OFF.
- All four sensors have been programmed.
- The TPM system has been in the program mode for longer
than 2 minutes and no sensors have been learned.
2. If the program mode is cancelled with less than four
codes stored, the receiver will only accept the codes programmed up to that point.
