Test Mode Procedure

SUSPENSION CONTROL: AIR SUSPENSION SYSTEM: TEST MODE PROCEDURE

1. TEST MODE PROCEDURE

HINT
* When entering the test mode, the suspension control ECU sets 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 erased. The test mode DTCs for other check items may not be erased when only a certain signal is inspected.
* When the test mode returns back to the normal mode, all the test mode DTCs will be erased.
(a) Turn the power switch OFF.

(b) Connect the Techstream to the DLC3.

(c) Turn the power switch ON (IG) and the Techstream ON.

(d) Enter the following menus: Chassis / Air suspension / Utility / Signal Check.

(e) Confirm that the system is in test mode by checking that the "SPORT" indicator light in the combination meter blinks at 0.125 second intervals (0.125 seconds on and 0.125 seconds off).

HINT
If the suspension control ECU does not store the vehicle identification information, the light blinks at 1 second intervals (1 second on and 1 second off). If the vehicle identification information is not stored, perform registration of the vehicle identification information Programming and Relearning.

(f) Read the test mode DTCs by following the prompts on the tester screen.

(g) After completing the test mode, disconnect the tester and turn the power switch OFF.

2. TEST MODE DTC CHART

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

(a) If a malfunction code is displayed during the test mode DTC check, check the circuit listed for that code. For details of each code, refer to "See page" for the respective "DTC Code" in the chart.
