Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | INSPECT WINDSHIELD WIPER AND WASHER SWITCH CONNECTOR • Disconnect the windshield wiper and washer switch connector. • Inspect the windshield 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.
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.
No | Go to the next step.
3 | INSPECT WINDSHIELD WIPER AND WASHER SWITCH SIGNAL CIRCUIT FOR SHORT TO GND • Inspect for continuity between BCM terminal 4I (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.
No | Go to the next step.
4 | INSPECT WINDSHIELD WIPER AND WASHER SWITCH • Inspect the windshield wiper and washer switch. (See WIPER AND WASHER SWITCH INSPECTION.) • Is there any malfunction? | Yes | Replace the windshield wiper and washer switch, then go to the next step. (See WIPER AND WASHER SWITCH REMOVAL/INSTALLATION.)
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 WDS or equivalent. • Is the same DTC present? | Yes | Replace the BCM. (See BODY CONTROL MODULE (BCM) REMOVAL/INSTALLATION.)
No | DTC troubleshooting completed.
