    • Is the resistance less than 5 ohms? 
    • Yes  : GO to B4.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  4. B4 CHECK THE LOCK/UNLOCK CIRCUITS BETWEEN THE DOOR LOCK CONTROL SWITCHES 
    • Disconnect: Driver Door Lock Control Switch C505.
    • Measure the resistance between the driver door lock control switch C505 pin 7, circuit 119 (PK/YE), harness side and the passenger door lock control switch C605 pin 8, circuit 119 (PK/YE), harness side.
