Diagnostic procedure

STEP	INSPECTION		ACTION
1	INSPECT REAR WIPER AND WASHER SWITCH CONNECTOR • Disconnect the rear wiper and washer switch connector. • Inspect the rear wiper and washer switch connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 5.
1		No	Go to the next step.
2	INSPECT BCM CONNECTOR • Disconnect the BCM connector. • Inspect the BCM connector terminals for poor connection (such as damaged/pulled-out pins, and corrosion). • Is there any malfunction?	Yes	Repair or replace the terminal, then go to Step 5.
2		No	Go to the next step.
3	INSPECT REAR WIPER AND WASHER SWITCH SIGNAL CIRCUIT FOR SHORT TO GND • Inspect for continuity between BCM terminal 3Q (wiring harness-side) and body GND. • Is there continuity?	Yes	Repair or replace the wiring harness for a possible short to GND, then go to Step 5.
3		No	Go to the next step.
4	INSPECT REAR WIPER AND WASHER SWITCH • Inspect the rear wiper and washer switch. (See REAR WIPER AND WASHER SWITCH INSPECTION.) • Is there any malfunction?	Yes	Replace the rear wiper and washer switch, then go to the next step. (See WIPER AND WASHER SWITCH REMOVAL/INSTALLATION.)
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the BCM memory using the M-MDS. • Perform the BCM DTC inspection. (See DTC INSPECTION [BCM].) • Is the same DTC present?	Yes	Replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)
5		No	DTC troubleshooting completed.
