With the scan tool, read DTC's.
Does the scan tool display active: B2324–HEADLAMP WASHER MOTOR CONTROL CIRCUIT HIGH?
Yes
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 - VER 1.
(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - STANDARD PROCEDURE)
2. CHECK HEADLAMP WASHER RELAY
Turn the ignition off.
Remove the Headlamp Washer relay.
Turn the ignition on.
Turn the Headlamp Washers on.
With the scan tool, read DTC's.
Does the scan tool display active: B2324–HEADLAMP WASHER MOTOR CONTROL CIRCUIT HIGH?
Yes
No
3.
(W24) HEADLAMP WASHER RELAY CONTROL CIRCUIT OPEN
Turn the ignition off.
Disconnect the TIPM C3 harness connector.
Measure the resistance of the (W24) Headlamp Washer Relay Control circuit between the Headlamp Washer Relay connector and the TIPM C3 harness connector.
Is the resistance below 10.0 ohms?
Yes
No
4.
(W24) HEADLAMP WASHER RELAY CONTROL CIRCUIT SHORTED TO VOLTAGE
Turn the ignition on.
Measure for voltage on the (W24) Headlamp Washer Relay Control circuit.
Is the voltage above 10.0 volts?
Yes
No
5. HEADLAMP WASHER RELAY
Turn the ignition off.
Replace the Headlamp Washer relay with a known good relay.
Turn the ignition on.
Turn the Headlamp Washers on.
With the scan tool, read DTC's.
Does the scan tool display active: B2324–HEADLAMP WASHER MOTOR CONTROL CIRCUIT HIGH?
Yes
No
6.
(W23) HEADLAMP WASHER MOTOR CONTROL CIRCUIT OPEN
Turn the ignition off.
Remove the Headlamp Washer relay.
Disconnect the Headlamp Washer Motor harness connector.
Measure the resistance of the (W23) Headlamp Washer Motor Control circuit at the Headlamp Washer Motor harness connector and the Headlamp Washer Relay connector.
Is the resistance below 10.0 ohms?
Yes
No
7.
(W23) HEADLAMP WASHER MOTOR CONTROL CIRCUIT SHORTED TO VOLTAGE
Turn the ignition on.
Measure for voltage on the (W23) Headlamp Washer Motor Control circuit.
Is the voltage above 10.0 volts?
Yes
No
