ADAPTIVE VARIABLE SUSPENSION SYSTEM TEST MODE PROCEDURE


  1. Note

    After replacing the absorber control ECU, it is necessary to perform registration of vehicle identification information. Vehicle identification information is automatically acquired when the system enters test mode.

    TEST MODE PROCEDURE


    1. Turn the power switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the power switch on (IG).

    4. Turn the GTS on.

    5. Enter the following menus: Chassis / Adaptive Variable Suspension System / Utility / Signal Check.


      Chassis > Adaptive Variable Suspension System > Utility
      Tester Display
      Signal Check

    6. Confirm that the system is in test mode by checking that the "SPORT S+" indicator in the combination meter assembly is blinking at 0.125-second intervals (0.125 seconds on and 0.125 seconds off).

      Tech Tips

      When vehicle identification information has not been acquired, the "Sport S+" indicator in the combination meter assembly blinks at 1-second intervals (1 second on and 1 second off). After vehicle identification information is acquired, the "Sport S+" indicator in the combination meter assembly blinks at 0.125-second intervals (0.125 seconds on and 0.125 seconds off).

    7. With the vehicle stationary on a level surface, wait for 1 second or more.

    8. Read the test mode DTCs by following the prompts on the GTS screen.

    9. End test mode by following the prompts on the GTS screen.

    10. Enter the following menus: Chassis / Adaptive Variable Suspension System / Data List.

    11. Check the value displayed on the GTS.

    12. Turn the power switch off and disconnect the GTS from the DLC3.

    13. TEST MODE DTC CHART

      If a trouble code is output during the test mode DTC check, check the circuit listed for that code. For details of each code, refer to Link for the respective DTC in the chart.
