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

POSSIBLE CAUSES
- Open fused B(+) circuits
- Central locking pump/security system module internal failure

DIAGNOSTIC TEST

1. MEASURE THE VOLTAGE OF THE CLP/SSM B(+) CIRCUIT




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

Q: Is the voltage above 10 volts?

YES: Go to 2
NO: Repair the Fused B(+) circuit for an open. Perform BODY VERIFICATION TEST. Body Verification Test

2. MEASURE THE VOLTAGE OF THE CLP/SSM B(+) CIRCUIT




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

Q: Is the voltage above 10 volts?

YES: Replace the Central Locking Pump/Security System Module. Perform BODY VERIFICATION TEST. Body Verification Test
NO: Repair the Fused B(+) circuit for an open.Perform BODY VERIFICATION TEST. Body Verification Test
