Test Mode Procedure [04/2013 - ]

WARNING: This page does not describe the selected car, but rather 27 other vehicles, including the 2024 Lexus IS 500, 2024 Lexus IS 350, 2024 Lexus IS 300, 2023 Lexus IS 500, and 2023 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
  1. TEST MODE PROCEDURE 
    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.
    • When vehicle identification information has not been acquired, the "SPORT S+" indicator in the multi-information display blinks at 1-second intervals (1 second on and 1 second off). After vehicle identification information is acquired, the "SPORT S+" indicator in the multi-information display blinks at 0.125-second intervals (0.125 seconds on and 0.125 seconds off).

    HINT: 

    • When entering test mode, the absorber control ECU stores all the test mode DTCs first.

      After completing the check for each test mode item, the test mode DTCs whose deletion conditions are met are cleared.

      The test mode DTCs for some items may not be cleared when only a certain signal is inspected.

    • When the system returns to normal mode, all the test mode DTCs will be cleared.
    1. Turn the engine switch off.
    2. Connect the Techstream to the DLC3.
    3. Turn the engine switch on (IG).
    4. Turn the Techstream on.
    5. Enter the following menus: Chassis / Air suspension / Utility / Signal Check.

    6. Confirm that the system is in test mode by checking that the "SPORT S+" indicator in the multi-information display 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 a second or more.
    8. Read the test mode DTCs by following the prompts on the Techstream screen.
    9. After completing test mode, disconnect the Techstream and turn the engine switch off.
  2. TEST MODE DTC CHART 

    HINT: 

    When entering test mode, the absorber control ECU stores all the test mode DTCs. If the deletion conditions for a test mode DTC are met, it is cleared.

    1. 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.
