Air Lumbar Support Switch

  1. The air lumbar support switch sends/receives signals via CAN communication, so it is not possible to check the electrical current of the switching components.
  2. Inspect the pneumatic lumbar support system using GDS.
    Check normal operation of the air lumbar support by selecting "Actuation Test" or "Current Data".
  3. Replace the faulty switch.
