Test F: The Door Lock Switches Operate Only One Way - Without Memory

PINPOINT TEST F: THE DOOR LOCK SWITCHES OPERATE ONLY ONE WAY - WITHOUT MEMORY

Normal Operation
The smart junction box (SJB) sends voltage signals to the door lock control switches through circuits CPL42 (GY/YE) and CPL43 (VT/GY) for the lock and unlock requests, respectively. When the lock or unlock switch is pressed, the voltage signal is routed to ground. The driver door lock control switch is grounded through circuit GD126 (BK/WH) and the passenger switch is grounded through circuit GD139 (BK/YE).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Door lock control switch
- SJB
