B2301-WIPER MODE SWITCH INPUT CIRCUIT LOW






For a complete wiring diagram refer to Diagrams/Electrical.

- When Monitored:
- With the ignition on.
- Set Condition:
- When the Instrument Cluster detects a short to ground condition.






Diagnostic Test

1. INTERMITTENT CONDITION

Turn the ignition on.

With the scan tool, clear all CCN DTC's.

Turn the Wipers ON then OFF.

With the Scan Tool, read the Wiper DTC's.

Does the scan tool read: B2301-WIPER MODE SWITCH INPUT 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. MULTIFUNCTION SWITCH





Turn the ignition off.

Disconnect the Multifunction Switch harness connector.

Ensure the Multifunction Switch is in the OFF position.

Measure the internal resistance of the Multifunction Switch between the (L900) and (W52) circuits.

Does the Switch measure more than 5.0 ohms?

Yes

- Replace the Multifunction Switch.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Go To 3
-

3. INSTRUMENT CLUSTER





Turn the ignition off.

Disconnect the Multifunction Switch connector.

Disconnect the Instrument Cluster C4 harness connector.

Measure the resistance of the (W52) Intermittent Wiper Switch Signal circuit to ground.

Is the resistance below 5.0 ohms?

Yes

- Repair the (W52) Intermittent Wiper Switch Signal circuit for a short to ground condition.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

- Replace the Instrument Cluster.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
