Check Damping Force Controlling Condition (Using SST Check Wire)

1. Checking the damping force controlling condition using the SST check wire.

SST 09843-18040

1. Using SST, connect terminals TS and CG of DLC3 with the ignition switch at OFF (Test Mode).
2. Start the engine.

   Under this condition, the absorber control actuator position is 1 (Soft).

3. Starting from the above mentioned position, as the brake pedal is depressed, the absorber control actuator position increases (1--> 2--> 3-->... 15--> 16). At this time, bounce the vehicle and check that the shock absorber becomes harder.

HINT:

• To hold the absorber control actuator at a specific position, adjust it to the position using the above mentioned procedure, and then increase the vehicle speed to over 5 km/h.

  After that speed is reached, the absorber control actuator position does not change until the ignition switch is turned to OFF.

• If the absorber control actuator does not operate, inspect the absorber control actuator circuit and the suspension control ECU.
