Test Mode Procedure [10/2017 - 10/2023]
- 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.
- Turn the power switch off.
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- Enter the following menus: Chassis / Adaptive Variable Suspension System / Utility / Signal Check.
Chassis > Adaptive Variable Suspension System > Utility
Tester Display Signal Check - 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).
HINT:
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).
- With the vehicle stationary on a level surface, wait for 1 second or more.
- Read the test mode DTCs by following the prompts on the Techstream screen.
- End test mode by following the prompts on the Techstream screen.
- Turn the power switch off and disconnect the Techstream from the DLC3.
