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 VTSS VERIFICATION TEST. VTSS 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 VTSS VERIFICATION TEST. VTSS Verification Test
NO: System voltage must be between 12 and 16 volts. Repair the voltage concern as necessary. Perform VTSS VERIFICATION TEST. VTSS Verification Test
