Programming
NOTE:
^ All keyless entry remote transmitters must be programmed at the same time.
^ To program (or reprogram) the keyless entry remote transmitter into the RAP module, perform the following steps:
1. Turn the ignition switch from OFF to RUN 8 times within 10 seconds, ending in RUN. If the RAP module has successfully entered program mode, it will lock and then unlock all doors.
2. Within 20 seconds, press any button on a keyless entry remote transmitter, and the doors will lock and then unlock to confirm that each keyless entry remote transmitter has been programmed. Repeat this step for each transmitter.
3. If the door locks do not respond for any keyless entry remote transmitter, wait several seconds and press the button again. If the door locks still fail to respond, refer to Inspection and Verification. Initial Inspection and Diagnostic Overview
4. Turn the ignition switch to the OFF position, or wait up 20 seconds after step 2, to exit program mode. If a keyless entry remote transmitter has been programmed (or reprogrammed), the RAP module will lock and unlock all doors one last time to confirm.
