TEST ACTION APPLICABILITY
3 Turn the ignition off.
Disconnect the Instrument Cluster harness connector.
Disconnect the Multi-Function Switch harness connector.
Check connectors - Clean/repair as necessary.
Measure the resistance of the Panel Lamps Dimmer Signal circuit.
Is the resistance below 5.0 ohms?
All
Yes → Go To 4
No → Repair the open in the Panel Lamps Dimmer Signal circuit.
Perform BODY VERIFICATION TEST - VER 1.
NOTE: Reconnect the Multi-Function Switch harness connector before
proceeding.
4 Turn the ignition off.
Disconnect the Multi-Function Switch harness connector.
Check connectors - Clean/repair as necessary.
Measure the resistance of the Multi-Function Switch Ground circuitto a known good
ground.
Does the resistance measure less than 5.0 ohms?
All
Yes → Go To 5
No → Repair the open in the Multi- Function Switch Ground circuit.
Perform BODY VERIFICATION TEST - VER 1.
5 Turn the ignition off.
Disconnect the Instrument Cluster harness connector.
Ensure the Multi-Function Switch is connected before proceeding.
Measure the resistance of the Panel Lamps Dimmer Signal circuit from the
Instrument Cluster harness connector to ground.
Move the Instrument Panel Dimmer Switch through the entire range of adjustment
while observing the ohmmeter.
Did the resistance increment smoothly between approximately 0.0 ohms to approx-
imately 3,500 ohms?
All
Yes → Replace the Instrument Cluster in accordance with the Service
Information.
Perform BODY VERIFICATION TEST - VER 1.
No → Replace theMulti-Function Switch inaccordance with theService
Information.
Perform BODY VERIFICATION TEST - VER 1.
