  13. All transmitters that are to be recognized by the Body Control Module (BCM) must be programmed in a single programming sequence. If system is placed in programming mode, it will erase all previously programmed transmitters upon receiving programming signal from the first transmitter. Perform programming procedure using ALL transmitters. See TRANSMITTER PROGRAMMING  under PROGRAMMING. Check RKE system operation. If RKE system operates properly, go to step  15 . If RKE system does not operate properly, go to next step.
