just had a new set of Michelin Pilots A/S runflats installed all around to replace original Goodyears FS1's. Anyway, with a sharpie, I marked the valve stems LF, RF, LR and RR thinking that the front and rear rims needed to stay on the same side due to the LTPWS sensors. I noticed that they got the Rear rims oriented correctly, but switched the front(right rim ended up on left side and left rim ended up on right). I know that older tire pressure sensors('90's) were designed so that one was designed for the left and the other was designed for the right. My question is this, on my 2000 C5, does it matter if the LTPWS sensors are swapped from Right to Left? They did of course get the tire rotation correct, so this is not a problem here.

Thanks in advance.....

 

I am not that familiar with the system, but I believe a relearn on the sensors will straighten it out again. Its not like the older C4 system.

 

Programming info below. A strong magnet will do for the programming tool.




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 canceled 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.

PROGRAMMING TPM SENSORS



Tools Required
J 41760 Tire Pressure Monitor (TPM) System Programming Tool.
IMPORTANT: Make sure the vehicle has been stationary for at least 2 minutes before attempting to program the TPM sensors.







Turn the ignition to ON.
Press the RESET button in order to clear any IPC display warning messages.
Press and release the OPTIONS button on the DIC to scroll through the display options until the IPC display is blank.
Press and hold the DIC RESET button for 3 seconds.
Press the OPTIONS button again until the TIRE TRAINING message appears. 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 in Body Control Systems.
Press the RESET button until the IPC LEARN L FRONT TIRE message appears in order to begin the programming sequence.
Install the J 41760 Tire Pressure Monitor (TPM) System Programming Tool over the left front valve stem.
The horn will sound, indicating the left front TPM sensor is programmed. NOTICE: 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
PROGRAMMING CANCELLATION


The programming mode will be canceled 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.
If the program mode is canceled with less than four codes stored, the receiver will only accept the codes programmed up to that point.
