1709-00
1709-00 SIREN NOT CONNECTED OR OPEN CIRCUIT
- When Monitored: Continuous.
- Set Condition: The Central Locking Pump/Security System Module (CLP/SSM) reports a short to power, ground, or an open circuit failure on the Siren Signal Output circuit.
Diagnostic Test
1. MEASURE THE RESISTANCE OF THE SIREN SIGNAL OUTPUT CIRCUIT
Turn the ignition off.
Disconnect the CLP/SSM harness connector.
Disconnect the Siren harness connector.
NOTE: Check connectors - Clean/repair as necessary.
Measure the resistance of the Siren Signal Output circuit from the CLP/SSM harness connector to the Siren harness connector.
Is the resistance below 5.0 ohms?
Yes
- Go to 2
No
- Repair the Siren Signal Output circuit for an open.
- Perform VTSS VERIFICATION TEST. VTSS Verification Test
2. MEASURE THE VOLTAGE OF THE SIREN SIGNAL OUTPUT CIRCUIT
Turn the ignition on.
Measure the voltage of the Siren Signal Output circuit at the Siren harness connector.
Is voltage present?
Yes
- Repair the Siren Signal Output circuit for a short to voltage.
- Perform VTSS VERIFICATION TEST. VTSS Verification Test
No
- Go to 3
3. MEASURE THE RESISTANCE OF THE SIREN SIGNAL OUTPUT CIRCUIT
Turn the ignition off.
Measure the resistance between ground and the Siren Signal Output circuit at the Siren harness connector.
Is the resistance below 10K ohms?
Yes
- Repair the Siren Signal Output circuit for a short to ground.
- Perform VTSS VERIFICATION TEST. VTSS Verification Test
No
- Replace the Siren.
- Perform VTSS VERIFICATION TEST. VTSS Verification Test
