Possible Causes

Circuit (GY/BR) open or short to ground
Circuit (GY/V) open or short to ground
Circuit (W/V) open or short to ground
Circuit (L/G) open or short to ground
Door lock actuator
SJB

CAUTION:

Use the correct probe adaptor(s) when making measurements. Failure to use the correct probe adaptor(s) may damage the connector.

A SINGLE DOOR LOCK IS INOPERATIVE - PINPOINT TEST REFERENCE

PINPOINT TEST 3		A SINGLE DOOR LOCK IS INOPERATIVE
STEP	INSPECTION		ACTION
1	CHECK CIRCUIT (GY/BR) OR CIRCUIT (W/V) FOR AN OPEN OR SHORT TO GROUND Disconnect: SJB J-2280b. Disconnect: Suspect door lock actuator connector. If the driver-side door lock actuator is inoperative, measure the resistance between the driver door lock actuator 0914-102 pin 1, circuit (GY/BR), harness side and ground; and between the driver door lock actuator 0914-102 pin 1, circuit (GY/BR), harness side and the SJB J-2280b pin 13, circuit (GY/BR), harness side. If the passenger-side door lock actuator is inoperative, measure the resistance between the passenger door lock actuator 0914-103 pin 1, circuit (W/V), harness side and ground; and between the passenger door lock actuator 0914-103 pin 1, circuit (W/V), harness side and the SJB J-2280b pin 9, circuit (W/V), harness side. Is the resistance greater than 10,000 ohms between the door lock actuator connector and ground, and less than 5 ohms between the door lock actuator and the SJB connector?	Yes	Go to next step.
1		No	Repair the circuit in question. Clear the DTCs. Repeat the self-test.
2	CHECK CIRCUIT (GY/V) OR CIRCUIT (L/G) FOR AN OPEN OR SHORT TO GROUND Disconnect: SJB J-2280c. If the driver-side door lock actuator is inoperative, measure the resistance between the driver door lock actuator 0914-102 pin 2, circuit (L/G), harness side and ground; and between the driver door lock actuator 0914-102 pin 2, circuit (L/G), harness side and the SJB J-2280c pin 12, circuit (L/G), harness side. If the passenger-side door lock actuator is inoperative, measure the resistance between the passenger door lock actuator 0914-103 pin 2, circuit (GY/V), harness side and ground; and between the passenger door lock actuator 0914-103 pin 2, circuit (GY/V), harness side and the J-2280b pin 10, circuit (GY/V), harness side. Is the resistance greater than 10,000 ohms between the door lock actuator connector and ground, and less than 5 ohms between the door lock actuator and the SJB connector?	Yes	Go to next step.
2		No	Repair the circuit in question. Clear the DTCs. Repeat the self-test.
3	CHECK THE SUSPECT DOOR LOCK ACTUATOR OPERATION Connect a fused (5A) jumper wire between the suspect door lock actuator connector pin 1, component side and the battery positive terminal; and between the suspect door lock actuator connector pin 2, component side and ground. Connect a fused (5A) jumper wire between the suspect door lock actuator connector pin 2, component side and the battery positive terminal; and between the suspect door lock actuator connector pin 1, component side and ground. Does the door lock actuator operate correctly?	Yes	Go to next step.
3		No	Install a new door lock. see DOOR LOCK ACTUATOR . Clear the DTCs. Repeat the self-test.
4	CHECK FOR CORRECT SJB OPERATION Disconnect all the SJB connectors. Check for: corrosion damaged pins pushed-out pins Connect all the SJB connectors and make sure they seat correctly. Operate the system and verify the concern is still present. Is the concern still present?	Yes	Install a new SJB. See SMART JUNCTION BOX (SJB) , . Clear the DTCs. Repeat the self-test.
4		No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. Clear the DTCs. Repeat the self-test.
