Test Mode Procedure

SUSPENSION CONTROL: AIR SUSPENSION SYSTEM: TEST MODE PROCEDURE

1. TEST MODE PROCEDURE

HINT
* When entering test mode, the suspension control ECU sets all the test mode DTCs first.
After completing 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.
* When the test mode returns back to the normal mode, all the test mode DTCs will be cleared.

(a) Turn the power switch off.

(b) Connect the Techstream to the DLC3.

(c) Turn the power switch on (IG).

(d) Turn the Techstream on.

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

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