C15B5-12

C15B5-12-LEFT FRONT DAMPING VALVE LOW SIDE 2 - CIRCUIT SHORT TO BATTERY

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
Ignition on. Battery voltage between 9 and 16 volts.

- Set Condition:
When the Adaptive Damping Control Module (ADCM) detects when the Left Front Damping Valve circuit is shorted to battery voltage while ignition is in the Run position.





1. VERIFY THE DTC IS ACTIVE
1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. With the scan tool, read the DTCs in the ADCM.

Is the DTC active at this time?

Yes

- Go To 2

No

- Go To 5

2. DAMPING VALVE SHOCK ASSEMBLY HARNESS CONNECTOR

NOTE: Make sure the Damping Valve Shock Assembly harness connector is connected correctly.

1. Turn the ignition off.
2. Inspect the Damping Valve Shock Assembly harness connector for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.

Were any problems found?

Yes

- Repair as necessary.
- Perform the ADCM VERIFICATION TEST. Active Damping Control Module (ADCM) Verification Test.

No

- Go To 3

3. CHECK THE (S131) LEFT FRONT DAMPER VALVE (-) CIRCUIT FOR A SHORT TO BATTERY
1. Turn the ignition off.
2. Disconnect the Damping Valve Shock Assembly harness connector.
3. Disconnect the ADCM C2 harness connector.
4. Turn the ignition on.
5. Measure the voltage between ground and the (S131) Left Front Damper Valve (-) circuit.

Is there any voltage present?

Yes

- Repair the (S131) Left Front Damper Valve (-) circuit for a short battery.
- Perform the ADCM VERIFICATION TEST. Active Damping Control Module (ADCM) Verification Test.

No

- Go To 4

4. ACTIVE DAMPING CONTROL MODULE (ADCM)
1. Replace the Active Damping Control Module (ADCM). Active Damping Control Module - Removal.
2. Perform the ADCM VERIFICATION TEST. Active Damping Control Module (ADCM) Verification Test.
3. Turn the ignition on.
4. With the scan tool, erase the DTCs.
5. Start the vehicle.
6. With the scan tool, read the DTCs in the ADCM.

Does the DTC remain active?

Yes

- Replace the Damping Valve Shock Assembly. Front Shock Absorber - Removal.
- Perform the ADCM VERIFICATION TEST. Active Damping Control Module (ADCM) Verification Test.

No

- Test complete.

5. INTERMITTENT WIRING AND CONNECTORS
1. Using the wiring diagram/schematic as a guide, inspect the wiring harness and connectors.
2. Wiggle test the wiring harness and connectors while monitoring the scan tool data relative to this circuit.
3. Look for the data to change or for the DTC to reset during the wiggle test.
4. While monitoring the scan tool data relative to this circuit, move the selector switch to each position several times.
5. Look for the data to change other than as expected or for the DTC to reset.

Were any problems found?

Yes

- Repair as necessary.
- Perform the ADCM VERIFICATION TEST. Active Damping Control Module (ADCM) Verification Test.

No

- Test complete, the condition or conditions that originally set this DTC are not present at this time.
