Test C: Transmitters Will Not Synchronize Or Program

  1. Perform Remote Keyless Entry (RKE) system check. See SYSTEM CHECK  under TROUBLE SHOOTING. Using scan tool, make sure Body Control Module (BCM) is in programming mode. Attempt to program transmitters, making sure to press buttons firmly. See PROGRAMMING  . If transmitters can be programmed, system is okay. If transmitters cannot be programmed, go to next step.
  2. If both driver and passenger door switches operate correctly, go to next step. If both driver and passenger door switches do not operate correctly, remove inspect BODY fuse from instrument panel fuse block. If fuse is bad, replace fuse. Check Orange wire between instrument panel fuse block and power window switches for short to ground. If wire is okay, see WIRING DIAGRAMS in POWER DISTRIBUTION for other possible short circuits. Repeat SYSTEM CHECK  under TROUBLE SHOOTING. If fuse is good, check for an open circuit or short to ground in Orange wire between instrument panel fuse block and BCM. Check BODY COMP fuse and replace as necessary. Install BODY fuse. Repeat SYSTEM CHECK  under TROUBLE SHOOTING.
  3. Using scan tool, monitor receipt of transmitter message. If scan tool shows receipt of scan tool message, problem is intermittent. Repeat SYSTEM CHECK  under TROUBLE SHOOTING. If scan tool does not show receipt of message, check battery in transmitter. Check for signal interference from anonymous radio transmissions. If problem was not found, replace BCM. See appropriate BODY CONTROL MODULES article.
