Diagnostic Test




1. MEASURE THE VOLTAGE OF THE CLP/SSM POWER CIRCUIT

Turn the ignition off.
Disconnect the CLP/SSM harness connector.
Measure the voltage of the Fused B(+) circuit (cavity 2) at the CLP/SSM C2 harness connector.

Q: Is the voltage between 12 and 16 volts?

YES: Go to 2
NO: System voltage must be between 12 and 16 volts. Repair the voltage concern as necessary. Perform BODY VERIFICATION TEST.




2. MEASURE THE VOLTAGE OF THE CLP/SSM POWER CIRCUIT

Measure the voltage of the Fused B(+) circuit (cavity 4) at the CLP/SSM C2 harness connector.

Q: Is the voltage between 12 and 16 volts?

YES: Replace the Central Locking Pump/Security System Module. Perform BODY VERIFICATION TEST. Body Verification Test
NO: System voltage must be between 12 and 16 volts. Repair the voltage concern as necessary. Perform BODY VERIFICATION TEST. Body Verification Test
