If transmitters cannot be programmed, go to next step.
- 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 BODY/CHIME fuse from instrument panel junction block. If fuse is bad, replace fuse. Repair short to ground in Orange wire between RKE module Black 16-pin connector terminal "E" and instrument panel junction block Gray 68-pin connector terminal B8. Repeat RKE SYSTEM CHECK under SYSTEM TESTS. If fuse is good, check for an open circuit or short to ground in Red wire between instrument panel junction block Black 68-pin connector terminal F5 and underhood junction block Black 2-pin connector terminal "B".
