B231F
B231F-FRONT/REAR WASHER MOTOR CONTROL CIRCUIT LOW
For a complete wiring diagram, refer to the Wiring Information.
- When Monitored:
With the ignition on.
- Set Condition:
When the Front Control Module (FCM) detects a short/low condition on the washer Pump Motor Control circuit.
1. INTERMITTENT CONDITION
1. Turn the ignition on.
2. Using the scan tool, clear all FCM DTCs.
3. Turn the Washers on.
4. Using the scan tool, read the Wiper/Washers DTCs.
Does the scan tool read: B231F-FRONT/REAR WASHER MOTOR CONTROL CIRCUIT LOW?
Yes
- Go To 2
No
- The condition that caused the symptom is currently not present. Inspect the related wiring for a possible intermittent condition. Look for any chafed, pierced, pinched, or partially broken wires.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
2. WASHER PUMP MOTOR
1. Turn the ignition off.
2. Disconnect the Washer Pump Motor connector.
3. Turn the ignition on.
4. Using the scan tool, read the DTCs.
Does the scan tool read:B231F-FRONT/REAR WASHER MOTOR CONTROL CIRCUIT LOW?
Yes
- Go To 3
No
- Replace the Washer Pump Motor.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
3. (W10)/(W20) WASHER PUMP MOTOR CONTROL CIRCUITS SHORT TOGETHER
1. Turn the ignition off.
2. Disconnect the Washer Pump Motor harness connector.
3. Disconnect the IPM C1 harness connector.
4. Measure the resistance between the (W10) and (W20) Washer Pump Motor Control circuits.

Yes
- Repair the (W10) and (W20) Washer Pump Motor Control circuits for a short together.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 4
4. (W10) WASHER PUMP MOTOR CONTROL CIRCUIT SHORT TO GROUND
1. Measure the resistance between ground and the (W10) Washer Pump Motor Control circuit.
Is the resistance below 5.0 Ohms?
Yes
- Repair the (W10) Washer Pump Motor Control circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Go To 5
5. (W20) WASHER PUMP MOTOR CONTROL CIRCUIT SHORT TO GROUND
1. Measure the resistance between ground and the (W20) Washer Pump Motor Control circuit.
Is the resistance below 5.0 Ohms?
Yes
- Repair the (W20) Washer Pump Motor Control circuit for a short to ground.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
No
- Replace the Front Control Module.
- Perform the BODY VERIFICATION TEST. Body Verification Test.
