Yes

- Go To 2

No

- The condition that caused this symptom is currently not present. Check for an intermittent condition by inspecting the related wiring harness for chafed, pierced, pinched, and partially broken wires. Also, inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals. Repair as necessary.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

2. CHECK HEADLAMP WASHER RELAY
1. Turn the ignition off.
2. Remove the Headlamp Washer relay.
3. Turn the ignition on.
4. Turn the Headlamp Washers on.
5. With the scan tool, read DTCs.
