B2318-WIPER HIGH/LOW CONTROL CIRCUIT HIGH





For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the Windshield Wipers on.

- Set Condition:
When the Totally Integrated Power Module (TIPM) detects a high condition in the wiper motor high speed control circuit.





1. INTERMITTENT CONDITION
1. Turn the ignition on.
2. With the scan tool, clear all TIPM DTCs.
3. Turn the Windshield Wipers on.
4. With the scan tool read the DTC information.

Does the scan tool read: B2318-WIPER HIGH/LOW CONTROL CIRCUIT HIGH?

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. (W4) WIPER MOTOR HIGH SPEED CONTROL OUTPUT CIRCUIT OPEN




1. Turn the ignition off.
2. Disconnect the TIPM C6 harness connector.
3. Disconnect the Wiper Motor harness connector.
4. Measure the resistance of the (W4) Wiper Motor High Speed Control Output circuit.

Is the resistance above 5.0 Ohms?

Yes

- Repair the (W4) Wiper Motor High Speed Control Output circuit for an open condition.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Go To 3

3. (W4) WIPER MOTOR HIGH SPEED CONTROL OUTPUT CIRCUIT SHORTED TO VOLTAGE




1. Turn the ignition off.
2. Disconnect the TIPM C6 harness connector.
3. Disconnect the Wiper Motor harness connector.
4. Turn the ignition on.
5. Measure for voltage on the (W4) Wiper Motor High Speed Control Output circuit.

Is the voltage above 10.0 volts?

Yes

- Repair the (W4) Wiper Motor High Speed Control Output circuit for a short to voltage condition.
- Perform the BODY VERIFICATION TEST. Body Verification Test.

No

- Replace the Totally Integrated Power Module (TIPM).
- Perform the BODY VERIFICATION TEST. Body Verification Test.
