How to fix TPMs and Keyless remotes not working?
Open the door to wake up the serial data bus, then verify the RCDLR functions normally. The correction at this time is to remove the fuse that powers the RCDLR and then reinstall the fuse. A software revision will be implemented and available in the near future.
What does the tire pressure monitor ( TPM ) do?
The RKE and Tire Pressure Monitor (TPM) are functions of the Remote Control Door Lock Receiver (RCDLR) with the exception of the 2006 Lucerne which uses the EBCM since there are no tire pressure sensors mounted inside the wheels. Open the door to wake up the serial data bus, then verify the RCDLR functions normally.
Why does my door lock and unlock remote not work?
The RKE transmitter rolling codes may become out of synchronization with the RCDLR and cause an intermittent operation of the door lock/unlock feature or remote start.
What to do if your TPMS won’t work?
Do not replace the RCDLR. Remove and replace the fuse that powers the RCDLR to restore communications. Press Lock, Unlock and Panic together and hold for 3-5 seconds. Perform transmitter learn procedure. Verify all functions. This can be done using the scan tool and monitoring the transmitter commands.
How to troubleshoot a tire pressure monitoring system?
1 Place the ignition switch in the “ACC” position. 2 Simultaneously press the keyless entry transmitter’s lock and unlock buttons until a horn chirp sounds. This will put the system in “learn mode.” 3 Starting with the left front tire, increase/decrease the tire pressure for 5 to 8 seconds, then wait for a horn chirp.
Open the door to wake up the serial data bus, then verify the RCDLR functions normally. The correction at this time is to remove the fuse that powers the RCDLR and then reinstall the fuse. A software revision will be implemented and available in the near future.
Why does my tire pressure sensor keep failing?
If this still doesn’t do the trick and the light is constantly on, it could be a sign that you have a faulty tire pressure sensor. It’s not uncommon for the sensor itself to fail. Why Do Tire Pressure Sensors Fail?
Do not replace the RCDLR. Remove and replace the fuse that powers the RCDLR to restore communications. Press Lock, Unlock and Panic together and hold for 3-5 seconds. Perform transmitter learn procedure. Verify all functions. This can be done using the scan tool and monitoring the transmitter commands.
