Component Testing

Door Lock Switch Test 

1. Ignition OFF, disconnect the harness connector at the appropriate door lock switch.
2. Test for infinite resistance between the signal terminals 2 and 1 and the ground terminal 3 with the switch in the open position.
   • If not the specified value, replace the door lock switch.
3. Test for less than 2 ohms between the signal terminal 1 and the ground terminal 3 with the switch in the LOCK position.
   • If greater than the specified range, replace the door lock switch.
4. Test for less than 2 ohms between the signal terminal 2 and the ground terminal 3 with the switch in the UNLOCK position.
   • If greater than the specified range, replace the door lock switch.

Door Latch 

1. Ignition OFF, disconnect the harness connector at the appropriate door latch
2. Install a 15A fused jumper wire between one of the control terminals and 12 V. Momentarily install a jumper wire between the other control terminal and ground. Reverse the jumper wires at least two times, the door latch should perform the LOCK/ UNLOCK functions.
   • If it does not perform as specified, replace the door latch
