SUSPENSION CONTROL: ACTIVE HEIGHT CONTROL SUSPENSION: TEST MODE PROCEDURE

1. TEST MODE PROCEDURE

* 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.
