Symptoms

  • The adaptive suspension or Ride Control lamp is on
  • The right front strut is fixed in one stiffness mode
  • Inability to switch suspension modes
  • Changes in handling, especially during maneuvers
  • The actuator circuit fuse may have tripped.

Causes

  • Short circuit of the actuator control wire to +12V
  • Damage to cable insulation near suspension elements (friction, kinks)
  • Internal short circuit in the shock absorber actuator winding
  • Moisture or foreign objects entering the connector
  • Malfunction of the adaptive suspension control unit

How to Fix

  1. Read the codes and check if there are related codes from other racks
  2. Check the suspension actuator circuit fuse
  3. Disconnect the actuator connector and check the voltage on the control wire (at normal - 0V without a signal)
  4. Inspect the cable from the actuator connector along its entire length for chafing.
  5. Measure the resistance of the actuator winding (infinity or very small - a sign of a short circuit)
  6. Replace the damaged cable or actuator and check the operation of the system
