My left rear tire sensor stopped reading. Got a blank screen or XXXX after driving for 10 minutes. Yesterday I had a new GM sensor installed in my tire and attempted to reprogram all the tire sensors. The 3 others work but the left rear still is blank or XXXX after driving. Suggestions please?

 

This makes no sense to me but others here have had luck bleeding some air out of the tire and refilling. This seems to some how "activate" the sensor.

Take a look here at post #4:

Tried it but unfortunately, it did not work. Any other suggestions please?

 

You said you attempted to reprogram the sensors. Did the car accept all 4?

 

Three tire programmed with horn. The left rear that is not working DID cause the horn to sound but still does not work. The right rear did not cause the horn to sound but it does show accurate tire pressure. Is there a receiving unit that might be bad on the left rear?

 

Are you starting at the correct corner and using a LARGE magnet? They have to be programmed in sequence.

XXXX shows a dead sensor battery. Doesn't sound like you had a successful reprogram after the old one failed.

The TPS sends an RF signal to the receiver and on to the computer. All you do when you reprogram is tell the computer which corner of the car that particular sensor is located. The beep tells you its been successfully detected and programmed.

Tire Pressure Monitoring 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 sensor's 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 identification code, all previously stored codes are erased from the receiver's memory.
J 41760 Tire Pressure Monitor (TPM) Programming Tool.
Tool required (any medium strength magnet, U or Disk type
1. Turn the ignition to ON.
2. Press the RESET button in order to clear any IPC display warning messages.
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.
Notice: Refer to Body Control Module (BCM) Programming/RPO Configuration in Cautions and Notices.
5. Press the OPTIONS button again until the TIRE TRAINING message appears.
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 Programming Tool over the left front valve stem.
8. The horn will sound, indicating the left front TPM sensor is programmed.
9. 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
Programming Cancellation
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
