Just had MRR wheels with Hankook tires put on. The shop said tire pressure monitors were installed. I watched them test a tire with their reader to show they were there. But my C5 can not read them during the “Learn” mode. They told me I’m supposed to hear a beep once the car reads the tire and be prompted to the next tire. Anyone have experienced this? Frustrating as wheels and tires are brand new and shop is telling me monitors were definitely installed.

Possibly the Shop did not know how to properly learn the sensors. Here is a method you can do yourself.

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.

Programming TPM Sensors

Tool Required

Tire Pressure Monitor (TPM) System Programming Tool Tire Pressure Monitor (TPM) System Programmer
(TPM System Programming Tool means "magnet" to ordinary C5 owners! Suggest having a strong magnet that circles the tire air valve)

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 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.

5. 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.

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

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.



The horn MUST beeped on all four sensors. If so you have to drive it for awhile to get correct reading.

Tony, many newer cars will automatically learn new sensors when installed. Some will even relearn the correct location of a sensor if you rotate the tires, my wife's 2016 Acura for example does that. Unfortunately the C5 will not. It requires a specific procedure as outlined by Ron above. The good news is that the procedure requires no more specific tools than a strong magnet - and some patience.

Also the C5 can be particular about which sensors will work in it. There have been a lot of posts here in the past about which ones work and some that don't (even new otherwise functioning sensors) in the C5.

Your dealer may have assumed that because his scanner could communicate with the sensors the car automatically would. Try the procedure Ron posted and let us know how it worked out. Don't be surprised if you may have to try it a few times to get it to take. Just be sure to use a strong magnet.

Good luck... GUSTO

"J 41760 Tire Pressure Monitor (TPM) System Programming Tool " This is nothing more than a very strong magnet, I used a big round one off a large speaker using the above procedure

Thank you. Yes we had tried a big magnet and since the learn sequence was not responsive, we took it back to the shop to double check they actually put in the pressure monitors when we picked up the new wheels and their sensor they said identified them. Still the car could not recognize them.

They need to be the right sensors for the year of your car for this to work, there was two systems on the C5

I bought these https://www.tpms.com/Schrader_28006_p/s8006.htm
Also bought the magnet and relearned each tire sensor as per instructions above.
