Test Mode Procedure

SUSPENSION CONTROL: ADAPTIVE VARIABLE SUSPENSION SYSTEM: TEST MODE PROCEDURE

1. INDICATOR LIGHT CHECK

(a) When the engine switch is turned on (IG), check that the absorber control indicator light will come on for approximately 2 seconds. (Absorber control switch is in the "NORMAL" position.)





HINT
If the absorber control ECU stores any DTCs, the absorber control indicator light will come on.

If the absorber control indicator light remains on or does not come on, proceed to troubleshooting for the indicator light circuit below.





2. SENSOR SIGNAL CHECK BY TEST MODE (SIGNAL CHECK)

HINT
* If the engine switch is turned from on (IG) to on (ACC) or off during Test Mode (SIGNAL CHECK), all Test Mode DTCs will be erased.
* During Test Mode (SIGNAL CHECK), the absorber control ECU records all Test Mode DTCs. By performing the Test Mode (SIGNAL CHECK), the codes will be erased if normality is confirmed. The remaining codes will be the codes where an abnormality was found.

(a) Procedure for Test Mode.

(1) Turn the engine switch off.

(2) Connect Techstream to the DLC3.

(3) Turn the engine switch on (IG).

(4) Set Techstream to Test Mode (select "SIGNAL CHECK").

HINT
Refer to Techstream operator's manual for further details.

(5) Start the engine without depressing the brake pedal.

(6) Check that the absorber control indicator light is blinking in Test Mode.





HINT
If the absorber control indicator light does not blink, inspect the absorber control indicator light circuit.





3. PERFORM SIGNAL CHECK BY TEST MODE (SIGNAL CHECK)

HINT
The "SPORT" indicator (absorber control indicator light) comes on for 1 second when inputting each diagnostic signal.

(a) Keep the absorber control switch in the "NORMAL" position.

(b) Keep the vehicle stationary on a level surface for 1 second or more (Acceleration sensor check).

(c) Turn the absorber control switch from the "NORMAL" to "SPORT" position and return to the "NORMAL" position. (An absorber control switch signal will be input.)

4. READ DTC

(a) Read the DTC(s) by following the tester screen.

HINT
See the list of Test Mode DTCs.

5. RESULT

Result:





6. END OF SENSOR CHECK

(a) Clear the DTCs Adaptive Variable Suspension System.





(b) Check that absorber control indicator light blinks (Test Mode).

(c) Turn both the engine switch off and Techstream switch off.

7. TEST MODE DTC (DTC of SIGNAL CHECK)





HINT
The codes in this table are output only in the test mode (SIGNAL CHECK).
