DOOR AJAR WARNING INDICATOR IS INOPERATIVE - PINPOINT TEST REFERENCE

PINPOINT TEST 17		DOOR AJAR WARNING INDICATOR IS INOPERATIVE
STEP	INSPECTION		ACTION
1	CHECK THE INTERIOR LAMPS FOR CORRECT OPERATION Open and close each door while monitoring the interior lamps. Do the interior lamps operate correctly?	Yes	Go to next step.
1		No	See INTERIOR LIGHTING , to continue diagnosis on the interior lamps.
2	CHECK THE DRIVER DOOR INPUT TO THE CLUSTER Key ON. Enter the following diagnostic mode on the scan tool: Instrument Cluster PID Select the instrument cluster external access ajar input switch status. Select and monitor the driver door ajar switch PID D_DR_SW while opening and closing the driver door. Does the PID match the door position with the door open and closed?	Yes	Go to next step.
2		No	Go to step 5.
3	RETRIEVE THE RECORDED DTCs FROM BOTH THE CONTINUOUS AND ON-DEMAND SJB SELF-TESTS Retrieve the recorded DTCs from the SJB continuous and on-demand self-tests. Are any DTCs retrieved?	Yes	If DTC U0140 is retrieved, CLEAR the DTCs. REPEAT the self-tests. If DTC U0140 is retrieved again, INSTALL a new SJB. See SMART JUNCTION BOX (SJB) , . For all other DTCs, see DIAGNOSTIC TROUBLE CODE (DTC) INDEX - B, C AND U CODES , .
3		No	Go to next step.
4	CARRY OUT THE INSTRUMENT CLUSTER WARNING LAMP AND CHIME ACTIVE COMMAND USING THE SCAN TOOL Key ON. Enter the following diagnostic mode on the scan tool: Instrument Cluster Active Command Select the instrument cluster warning lamp and chime active command. Select the door ajar warning lamp active command on then off again. Observe the door ajar indicator. Does the door ajar warning indicator illuminate when commanded on and turn off when commanded off?	Yes	Go to step 7.
4		No	Go to step 8.
5	CHECK THE SJB FOR AN OPEN Key OFF. Disconnect: SJB J-2280c. Connect a fused (5A) jumper between the SJB J-2280C pin 2, circuit (V/O), harness side and ground. Key ON. Enter the following diagnostic mode on the scan tool: Instrument Cluster PID Select the instrument cluster external access ajar input switch status. Select and monitor the driver door ajar switch PID D_DR_SW while opening and closing the driver door. Does the PID indicate the door closed with the jumper wire disconnected and open with the jumper wire connected?	Yes	Go to step 7.
5		No	Go to next step.
6	CHECK CIRCUIT (V/O) FOR AN OPEN Key OFF. Disconnect: Instrument cluster 0922-102. Measure the resistance between the instrument cluster 0922-102 pin 2, circuit (V/O), harness side and the SJB J-2280c pin 2, circuit (V/O) harness side. Is the resistance less than 5 ohms?	Yes	Go to step 8.
6		No	Repair the circuit. Test the system for normal operation.
7	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) , . Test the system for normal operation.
7		No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
8	CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION Disconnect all the instrument cluster connectors. Check for: corrosion damaged pins pushed-out pins Connect all the instrument cluster 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 instrument cluster. see INSTRUMENT CLUSTER . Test the system for normal operation.
8		No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
