Active Height Control Suspension -- Test Mode Procedure



TEST MODE PROCEDURE
HINT:
  1. When entering the test mode, the suspension control ECU stores all the test mode DTCs first. After completing the test mode for each check item, the test mode DTCs that are determined to be normal by the suspension control ECU will be cleared. The test mode DTCs for other check items may not be cleared when only a certain signal is inspected.
  2. When the test mode returns back to the normal mode, all the test mode DTCs will be cleared.

  1. Turn the engine switch off.

  2. Connect the GTS to the DLC3.

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

  4. Enter the following menus: Chassis / AHC / Utility / Signal Check.

  5. Read the test mode DTCs by following the prompts on the tester screen.

  6. After completing the test mode, disconnect the GTS and turn the engine switch off.
