  6. Check absorber control actuator operation.
    Starting from the above mentioned position, as the brake pedal is depressed, the absorber control actuator position will increase by 2 steps (1 (SOFT) → 3 → 5 → 7 → 9 → 11 → 15 → 17 (HARD)).
    At this time, bounce the vehicle and check that the shock absorber is becoming harder.

    HINT:
    1. To hold the absorber control actuator at a specific position, adjust it using the above mentioned procedure, then increase the vehicle speed to 5 km/h (3 mph).
      After that, the absorber control actuator position does not change until the engine switch is turned off.
    2. If the absorber control actuator does not operate, inspect the absorber control actuator circuit and absorber control actuator installation condition.

  7. Turn the engine switch off.

  8. Remove the SST from terminal TS and CG of the DLC3.

  9. Turn the engine switch on (IG).

    HINT:
    If the engine switch remains on (IG) after the SST is removed from DLC3, the vehicle will remain in the previously initialized Test Mode.
