1729-00 CENTRAL LOCKING PUMP/SECURITY SYSTEM MODULE SYSTEM INTERNAL FAILURE:

WHEN MONITORED
Continuous.

SET CONDITION
If the Central Locking Pump/Security System Module (CLP/SSM) detects an internal malfunction, the DTC is set.

- No power to central locking pump/security system module
- Central locking pump/security system module

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.
