WHEN MONITORED
With the Ignition on
SET CONDITION
The CCN detects an open condition
POSSIBLE CAUSES
- Multifunction switch
- Wiper/turn/beam select switch sense
- Turn lamps switch
- Feed circuit
- Instrument cluster
1. INTERMITTENT CONDITION
Turn the ignition on.
With the DRBIII(R), clear all MIC DTC's.
Actuate the Hazard Lamps.
With the DRBIII(R), read the DTC information.
Q: Does the DRBIII(R) read: Turn Hazard Switch Input Circuit Open?
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. MULTIFUNCTION SWITCH
Disconnect the Multifunction Switch connector.
Turn the ignition on.
Measure the voltage of the Multifunction Switch between the Sense circuit and the Feed circuit.
Q: Does the voltage read 0.0 volts?
YES: Replace the Multifunction Switch. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Go To 3
3. WIPER/TURN/BEAM SELECT SWITCH SENSE
Turn the ignition off.
Disconnect the Multifunction Switch connector.
Disconnect the Instrument Cluster C4 connector.
Measure the resistance of the Wipe/Turn/Beam select sense circuit.
Q: Is the resistance below 5.0 ohms?
YES: Go To 4
NO: Repair the Wiper/Turn/Beam Select Switch Sense circuit. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
4. INSTRUMENT CLUSTER
Turn the ignition off
Disconnect the Multifunction Switch connector.
Disconnect the Instrument Cluster C4 connector.
Measure the resistance of the Turn Lamps Switch Feed circuit.
Q: Is the resistance below 5.0 ohms?
YES: Replace the Instrument Cluster. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Repair the Turn Lamps Switch Feed circuit. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
