The BCM will cease processing any remote control door lock transmitter digital RF messages (good or bad) for 20 seconds.

CONDITIONS FOR SETTING THE DTC
The remote control door lock transmitter has been in the program mode out of range of the BCM. This malfunction could also occur if the remote control door lock transmitter itself is defective.

ACTION TAKEN WHEN THE DTC SETS
No remote function capability.

CONDITIONS FOR CLEARING THE MIL/DTC
Fault is corrected and DTC memory clearing procedure is completed.

DIAGNOSTIC AIDS
A possible cause is the remote control door lock transmitter is out of sync with BCM. To synchronize the transmitter to the BCM, press the lock and unlock buttons on the transmitter at the same time for 5 seconds. This malfunction could be induced prior to the BCM entering the diagnostic mode.
