MIC-Wash-Beam Input Circuit Shorted

MIC-WASH-BEAM INPUT CIRCUIT SHORTED

MIC - Wash-Beam Input Circuit Shorted:

WHEN MONITORED
With the ignition on.

SET CONDITION
The Instrument Cluster detects less than 0.05 volts on the Wash/Beam Select Switch Feed circuit.

POSSIBLE CAUSES
- Multi-function switch
- Instrument cluster
- (G194) Wash/beam select switch feed circuit short to ground

1. INTERMITTENT CONDITION




Turn the ignition on.
With the DRBIII(R), clear all MIC DTC's.
Turn the Wipers on.
With the DRBIII(R), read the DTC information.

Q: Does the DRBIII(R) read: Wash-Beam Input Circuit Shorted?

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 BODY VERIFICATION TEST - VER 1. Body Verification Test

2. MULTI-FUNCTION SWITCH
Turn the ignition off.
Disconnect the Multi-Function Switch harness connector.
Turn the ignition on.
With the DRBIII(R) in Sensors, read the Wash - Beam SW Volts.

Q: Does the DRBIII(R) display more than 4.5 volts?

YES: Replace the Multi- Function Switch. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 3

3. WASH/BEAM SELECT SWITCH FEED CIRCUIT SHORT TO GROUND




Turn the ignition off.
Disconnect the Instrument Cluster C4 harness connector.
Disconnect the Multi- Function Switch harness connector.
Measure the resistance between ground and the(G194) Wash/beam Select Switch Feed circuit.

Q: Is the resistance below 5.0 ohms?

YES: Repair the (G194) Wash/Beam Select Switch Feed circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace and configure the Instrument Cluster. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
