WIPERS STAY ON CONTINUOUSLY - PINPOINT TEST REFERENCE

PINPOINT TEST 2		THE WIPERS STAY ON CONTINUOUSLY
STEP	INSPECTION		ACTION
1	RETRIEVE THE DIAGNOSTIC TROUBLE CODES (DTCs) Retrieve and document continuous DTCs. Enter the following diagnostic mode on the scan tool: Clear continuous DTCs Enter the following diagnostic mode on the scan tool: SJB wiper/washer self-test Are DTCs present?	Yes	If DTC B1431, go to next step. If DTC B1446, go to step 3. If DTC B2179, B2180, B2181 or B2183, go to step 6.
1		No	Carry out the run/park relay component test. If the relay tests OK, go to step 7.
2	CHECK CIRCUIT (G/V) FOR A SHORT TO GROUND Key in OFF position. Disconnect: Wiper run/park relay. Disconnect: SJB J-2280a. Measure the resistance between ground and wiper run/park relay pin 2, circuit (G/V). Is the resistance greater than 10,000 ohms?	Yes	Go to step 8.
2		No	Repair circuit (G/V) for a short to ground. Test the system for normal operation.
3	CHECK CIRCUIT (BR/L) FOR A SHORT TO VOLTAGE Key in OFF position. Disconnect: SJB J-2280a. Disconnect: Wiper motor 0919-101. Key in ON position. Measure the voltage between ground and wiper motor 0919-101 pin 5, circuit (BR/L). Is voltage present?	Yes	Repair circuit (BR/L) for a short to voltage. Test Die system for normal operation.
3		No	Go to next step.
4	CHECK CIRCUIT (L/GY) FOR VOLTAGE Key in OFF position. Disconnect: Wiper run/park relay. Key in ON position. Measure the voltage between ground and wiper run/park relay pin 3, circuit (L/GY). Is voltage present?	Yes	Go to next step.
4		No	Go to step 8.
5	CHECK CIRCUIT (L/GY) FOR A SHORT TO VOLTAGE Key in OFF position. Disconnect: Wiper high/low relay. Key in ON position. Measure the voltage between ground and wiper run/park relay pin 3, circuit (L/GY). Is voltage present?	Yes	Repair circuit (L/GY) for a short to voltage. Test the system for normal operation.
5		No	Repair circuit (L/G) for a short to voltage. Test the system for normal operation.
6	CHECK CIRCUITS (G/V), (V/W), (L/O) AND (BR/W) FOR A SHORT TO GROUND Key in OFF position. Disconnect: SJB J-2280d. Disconnect: Multifunction switch 0918-104. Measure the resistance between ground and multi-function switch: (DTC B2179) 0918-104 pin 1, circuit (G/V). (DTC B2180) 0918-104 pin 2, circuit (L/O). (DTC B2181) 0918-104 pin 3, circuit (V/W). (DTC B2183) 0918-104 pin 4, circuit (BR/W). Is the resistance greater than 10,000 ohms?	Yes	Carry out the multi-function switch component test. See table at the end of test. If the switch tests OK, go to step 8.
6		No	Repair circuit (G/V), (L/O), (V/W) or (BR/W) for a short to ground. Test the system for normal operation.
7	CHECK CIRCUIT (V/O) FOR A SHORT TO VOLTAGE Key in OFF position. Disconnect: Wiper high/low relay. Disconnect: Wiper motor 0919-101. Key in ON position. Measure the voltage between ground and wiper high/low relay pin 5, circuit (V/O). Is voltage present?	Yes	Repair circuit (V/O) for a short to voltage. Test the system for normal operation.
7		No	Go to next step.
8	CHECK FOR CORRECT SJB OPERATION Disconnect all 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.
8		No	The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector. Clear the DTCs. Repeat the self-test.
