B231F
B231F-FRONT/REAR WASHER MOTOR CONTROL CIRCUIT LOWB231F - Front/rear Washer Motor Control Circuit Low:
WHEN MONITORED
With the ignition on.
SET CONDITION
When the TIPM detects a short/low condition on the washer Pump Motor Control circuit.
POSSIBLE CAUSES
- (W10)/(W20) Washer pump motor control circuit short together
- (W10) Washer pump motor control circuit short to ground
- (W20) Washer pump motor control circuit short to ground
- Wiper washer pump
- Totally integrated power module
Diagnostic Test
1. INTERMITTENT CONDITION
Turn the ignition on.
With the Scan Tool, clear all TIPM DTC's.
Turn the Washers on.
With the Scan Tool, read the Wiper/Washers DTC's.
Q: 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 - VER 1. Body Verification Test
2. WASHER PUMP MOTOR
Turn the ignition off.
Disconnect the Washer Pump Motor connector.
Turn the ignition on.
With the Scan Tool, read the DTC's.
Q: 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 - VER 1. Body Verification Test
3. (W10)/(W20) WASHER PUMP MOTOR CONTROL CIRCUITS SHORT TOGETHER
Turn the ignition off.
Disconnect the Washer Pump Motor harness connector.
Disconnect the TIPM C1 harness connector.
Measure the resistance between the (W10) and (W20) Washer Pump Motor Control circuits.
Q: Is the resistance below 5.0 ohms?
YES: Repair the (W10) and (W20) Washer Pump Motor Control circuits for a short together. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 4
4. (W10) WASHER PUMP MOTOR CONTROL CIRCUIT SHORT TO GROUND
Measure the resistance between ground and the (W10) Washer Pump Motor Control circuit.
Q: 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 - VER 1. Body Verification Test
NO: Go To 5
5. (W20) WASHER PUMP MOTOR CONTROL CIRCUIT SHORT TO GROUND
Measure the resistance between ground and the (W20) Washer Pump Motor Control circuit.
Q: 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 - VER 1. Body Verification Test
NO: Replace the Totally Integrated Power Module. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
