Driver Cylinder Lock Switch Input Circuit Shorted (With VTSS Only):

WHEN MONITORED
At all times when battery power is supplied to the Instrument Cluster.

SET CONDITION
When the Instrument Cluster senses voltage to the driver cylinder lock switch below 0.25 volts for over 10 seconds.

POSSIBLE CAUSES
- (G163) Driver cylinder lock switch mux circuit short to ground
- Cylinder lock switch shorted
- Instrument cluster

Diagnostic Test

1. DTC PRESENT




Turn the ignition on.
With the DRBIII(R), record and erase DTC's.
With the DRBIII(R), read DTC's.
Operate the door locks several times from the Driver Cylinder Lock Switch by cycling the key clockwise while monitoring the DRBIII(R).

Q: Does the DRBIII(R) display DRIVER CYL LOCK SW INPUT CIRCUIT SHORTED?

YES: Go To 2
NO: Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. CYLINDER LOCK SWITCH SHORTED




Disconnect the Driver Cylinder Lock Switch connector.
With the DRBIII(R) in Sensors, read the DRV CYL LOCK SW MUX circuit

Q: Is the voltage above 4.8 volts?

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

3. (G163) DRIVER CYLINDER LOCK SWITCH MUX SHORTED




Disconnect the Driver Cylinder Lock Switch connector.
Disconnect the Instrument Cluster C2. connector.
Measure the resistance between (G163) Driver Cylinder Lock Switch Mux circuit and ground.

Q: Is the resistance below 1000.0 ohms?

YES: Repair the (G163) Driver Cylinder Lock Switch Mux circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Replace the Instrument Cluster. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test
