Normal Operation
The driver door module (DDM) monitors the RKE keypad through circuits 78 (LB/YE), 79 (LG/RD) and 121 (YE/BK). The RKE keypad is grounded through circuit 57 (BK). As each button is pressed a connection to ground through individual resistors occurs. The DDM receives the ground signals from the RKE keypad and operates the locks accordingly.

Possible Causes
- circuit 57 (BK)
- circuit 78 (LB/YE) open or short to ground
- circuit 79 (LG/RD) open or short to ground
- circuit 121 (YE/BK) open or short to ground
- RKE keypad
- DDM
