1 Turn the ignition on.
With the DRBIII(R), erase DTCs.
Operate the door locks from both cylinder lock switches several times.
With the DRBIII(R), read DTCs.
Does the DRBIII(R) display CYLINDER LOCK SWITCH FAILURE?
  1. Yes --> Go To 2
  2. No --> Problem is intermittent and not present at this time. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors and repair as necessary.

    Perform BODY VERIFICATION TEST - VER 1  .
2 With the DRBIII(R) in Sensors, read the CYLINDER LOCK SWITCH Voltage.
Select the Voltage that is present:
  1. Below. 3 volts.
    1. Go To 3
  2. Above 5.5 volts.
    1. Go To 5
  3. 3.1 to 5.4 volts.
    1. No trouble found. The voltage is correct at this time. Retry the system and recheck the trouble code.
    2. Perform BODY VERIFICATION TEST - VER 1  .
3 Turn the ignition off.
Disconnect the Central Timer Module C2 connector.
Measure the resistance between ground and the Cylinder Lock Switch Mux circuit.
Is the resistance below 500.0 ohms?
  1. Yes --> Go To 4
  2. No --> Replace the Central Timer Module.

    Perform BODY VERIFICATION TEST - VER 1  .
4 Turn the ignition off.
Disconnect the Central Timer Module C2 connector.
Measure the resistance between ground and the Cylinder Lock Switch Mux circuit in the CTM C2 connector.
Disconnect the Driver Cylinder Lock Switch and then the Passenger Cylinder Lock Switch while monitoring the Ohmmeter
Did the resistance rise well above 500.0 ohms when one or both of the switches was disconnected?
  1. Yes --> Replace the necessary Cylinder Lock Switch.

    Perform BODY VERIFICATION TEST - VER 1  .

  2. No --> Repair the Cylinder Lock Switch Mux wire for a short to ground.

    Perform BODY VERIFICATION TEST - VER 1  .
5 Turn the ignition off.
Disconnect the Central Timer Module C2 connector.
Measure the resistance between ground and the Cylinder Lock Switch Mux circuit in the CTM C2 connector.
Is the resistance below 12000.0 ohms?
  1. No --> Repair the Cylinder Lock Switch Mux circuit for an open from the CTM to the Cylinder Lock Switches.

    Perform BODY VERIFICATION TEST - VER 1  .

  2. Yes --> Go To 6
6 Turn the ignition off.
Disconnect the Central Timer Module C2 connector.
Turn the ignition on.
Measure the voltage of the Cylinder Lock Switch Mux circuit in the CTM C2 connector.
Is there any voltage present?
  1. Yes --> Repair the Cylinder Lock Switch Mux circuit for a short to voltage.

    Perform BODY VERIFICATION TEST - VER 1  .

  2. No --> Go To 7
7 With the DRBIII(R), check the Vehicle Theft Security System (VTSS) status.
Is the VTSS enabled?
  1. Yes --> Go To 8
  2. No --> With the DRBIII(R), enable the Vehicle Theft Security System. Erase DTC's and recheck for trouble codes. If this DTC reappears, replace the Central Timer Module.

    Perform BODY VERIFICATION TEST - VER 1  .
8 If there are no possible causes remaining, view repair.
  1. Repair
    1. Replace the Central Timer Module.
    2. Perform BODY VERIFICATION TEST - VER 1  .
