CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read ADCM DTCs and record on the repair order.
3. With the scan tool, erase DTCs.
4. Start the Engine.
5. With the scan tool, read ADCM DTCs.
  Is the DTC active?
  
  Yes
  - Go To 2
  No
  - Go To 6
LEFT FRONT ACCELERATION SENSOR HARNESS CONNECTOR
NOTE:
Make sure the Acceleration Sensor harness connector is connected correctly.
1. Turn the ignition off.
2. Inspect the Acceleration Sensor harness connector for signs of water intrusion, corrosion, pushed out or bent terminals, and correct pin tension.
3. Wiggle test the wiring harness and connectors while monitoring the scan tool data relative to this circuit.
  Were any problems found?
  
  Yes
  - Repair as necessary.
  - Perform the ADCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 3
CHECK THE (S162) LEFT FRONT ACCELERATION SENSOR SIGNAL CIRCUIT FOR A SHORT TO BATTERY
1. Turn the ignition off.
2. Disconnect the Left Front Acceleration Sensor harness connector.
3. Disconnect the ADCM C1 harness connector.
4. Turn the ignition on.
5. Measure the voltage between ground and the (S162) Left Front Acceleration Sensor Signal circuit.
  Is the voltage above 5.25 volts?
  
  Yes
  - Repair the (S162) Left Front Acceleration Sensor Power circuit for a short battery.
  - Perform the ADCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 4
CHECK THE (S161) LEFT FRONT ACCELERATION SENSOR RETURN CIRCUIT FOR AN OPEN OR HIGH RESISTANCE
1. Turn the ignition off.
2. Measure the resistance of the (S161) Right Front Acceleration Sensor Return circuit between the Left Front Acceleration Sensor harness connector and the ADCM C1 harness connector.
  Is the resistance above 5.0 Ohms?
  
  Yes
  - Repair the (S161) Right Front Acceleration Sensor Return circuit for an open or high resistance.
  - Perform the ADCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Go To 5
ACCELERATION SENSOR
1. Replace the Acceleration Sensor in accordance with the Service Information. Refer to SENSOR, ACTIVE DAMPING, REMOVAL .
2. Perform the ADCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
3. Turn the ignition on.
4. With the scan tool, erase the DTCs.
5. Start the Engine.
6. With the scan tool, read ADCM DTCs.
  Does the DTC remain active?
  
  Yes
  - Replace the Active Damping Control Module (ADCM) in accordance with the Service Information. Refer to MODULE, ACTIVE DAMPING CONTROL (ADCM), REMOVAL .
  - Perform the ADCM VERIFICATION TEST. Refer to STANDARD PROCEDURE .
  No
  - Test complete.
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. Refer to STANDARD PROCEDURE .
  No
  - Test complete, the condition or conditions that originally set this DTC are not present at this time.
