Are they OK?
YES -
Go to step 3.
NO -
Reinstall or replace the appropriate suspension stroke sensor, or linkage See: Sensors and Switches/Sensors and Switches - Steering and
Suspension/Sensors and Switches - Suspension/Ride Height Sensor/Service and Repair.?
3. Remove the right-rear and left-rear suspension stroke sensors See: Sensors and Switches/Sensors and Switches - Steering and
Suspension/Sensors and Switches - Suspension/Ride Height Sensor/Service and Repair. Do not disconnect the sensor connector.
NOTE: After troubleshooting for the left side suspension stroke sensor, do the headlight initial position learning procedure See: Lighting and
Horns/Testing and Inspection/Programming and Relearning.
4. Start the engine, and wait 5 seconds.
5. Check the SUS STROKE_S VOLTAGE (RR), or (LR) in the ACTIVE DAMPER SYSTEM DATA LIST with the HDS while moving the
suspension stroke sensor arm through a complete stroke. Compare the voltage/rotation angle between the chart and the measurements.
NOTE: The voltage should increase (decrease) within 90 degrees of the sensor arm rotation from the first voltage change point.
Is the voltage as specified?
YES -
Replace the active damper control unit See: Relays and Modules/Relays and Modules - Steering and Suspension/Relays and Modules -
Suspension/Suspension Control Module/Service and Repair.?
NO -
Replace the appropriate suspension stroke sensor See: Sensors and Switches/Sensors and Switches - Steering and Suspension/Sensors and
Switches - Suspension/Ride Height Sensor/Service and Repair.?
2-1
Active Damper System DTC Troubleshooting: 2-1, 2-3
DTC 2-1:
Right-front Suspension Stroke Sensor Circuit High Voltage
DTC 2-3:
Right-rear Suspension Stroke Sensor Circuit High Voltage
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Turn the ignition switch to LOCK (0).
4. Start the engine, and wait 5 seconds.
