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 Passenger Door Lock Switch while monitoring the DRBIII(R).

Q: Does the DRBIII(R) display PASSENGER DOOR LOCK SWITCH INPUT CIRCUIT STUCK?

YES: Go To 2
NO: Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Operate the switch several times and check for an occasional sticking problem. Perform BODY VERIFICATION TEST - VER 1. Body Verification Test

2. DOOR LOCK SWITCH STUCK




Disconnect the Passenger Door Lock Switch connector.
With the DRBIII(R) in sensors, read the PASS DOOR LOCK SW MUX circuit.

Q: Is the voltage above 4.6 volts?

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

3. (G160) PASSENGER DOOR LOCK SWITCH MUX CIRCUIT SHORTED




Turn the ignition off.
Disconnect the Instrument Cluster C4 connector.
Measure the resistance between the (G160) Passenger Door Lock Switch Mux circuit and ground.

Q: Is the resistance below 10000.0 ohms?

YES: Repair the (G160) Passenger Door Lock Switch Mux circuit for a partial 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
