- Is the voltage greater than 10 volts?
- Yes : GO to G2.
- No : GO to G3.
G2 CHECK CIRCUIT 343 (DB/LG) FOR A SHORT TO VOLTAGE
- Disconnect: Instrument Cluster C220b.
- Key in ON position.
- Measure the voltage between the vehicle security module C203a-10, circuit 343 (DB/LG), harness side and ground.

- Is any voltage indicated?
- Yes : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
- No : GO to G5.
G3 CHECK CIRCUIT 343 (DB/LG) FOR AN OPEN
- Disconnect: Instrument Cluster C220b.
- Measure the resistance between the vehicle security module C203a-10, circuit 343 (DB/LG), harness side and the instrument cluster C220b-10, circuit 343 (DB/LG), harness side.

- Is the resistance less than 5 ohms?
- Yes : GO to G4.
- No : REPAIR the circuit. CLEAR the DTCs. REPEAT the self-test.
G4 CHECK FOR CORRECT INSTRUMENT CLUSTER OPERATION
- Key in OFF position.
- Disconnect all instrument cluster connectors.
- Check for:
  - corrosion
  - pushed-out pins
- Connect all instrument cluster connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new instrument cluster. REFER to INSTRUMENT CLUSTER . TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
G5 CHECK FOR CORRECT VEHICLE SECURITY MODULE OPERATION
- Key in OFF position.
- Disconnect all vehicle security module connectors.
- Check for:
  - corrosion
  - pushed-out pins
- Connect all vehicle security module connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new vehicle security module. REFER to MULTIFUNCTION ELECTRONIC MODULES . TEST the system for normal operation.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
