C15BF-2A-DAMPING MODE BUTTON - STUCK

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

Theory of Operation
The Active Damping Control Module (ADCM) detects the Damping Mode button switch information by receiving messages from the CAN communications bus. Specifically the UP button is wired to the cluster, the cluster sends this information via CAN I to the TIPM, and TIPM sends it onto the ADCM via CAN C.
- When Monitored:
Ignition on. Battery voltage between 9 and 16 volts.

- Set Condition:
Damping suspension button has been pressed continuously for more than 17 seconds while the 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 SUSPENSION SWITCH IN THE PRESSED POSITION
1. Turn the ignition off.
2. Inspect the Damping Mode switch for foreign material which could keep it from returning back to the not pushed state.
3. Turn the ignition on.
4. Using the scan tool, monitor the Damping Mode Switch status in the ADCM while pressing and releasing the switch.

Does the Damping Mode Switch function correctly?

Yes

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

No

- Go To 3

3. DAMPING MODE SWITCH
1. Turn the ignition off.
2. Replace the Damping Mode Switch.Perform the ADCM VERIFICATION TEST. Active Damping Control Module (ADCM) Verification Test.
3. Turn the ignition on.
4. With the scan tool, record and erase DTCs.
5. With the scan tool, read the DTCs in the ADCM.

Does the DTC remain active?

Yes

- Go To 4

No

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

4. INSTRUMENT CLUSTER
1. Turn the ignition off.
2. Replace the Instrument Cluster. Instrument Cluster - Removal.
3. Turn the ignition on.
4. With the scan tool, record and erase DTCs.
5. With the scan tool, read the DTCs in the ADCM.

Does the DTC remain active?

Yes

- Replace the Active Damping Control Module (ADCM). Active Damping Control Module - Removal.
- 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.

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.
