DIAGNOSIS FUNCTION

ASC-ECU has the following functions for easier system checks. The following items can be diagnosed using M.U.T-III.

Diagnosis code set (Refer to ).
Service data output (Refer to ).
Actuator test (Refer to ).

FAIL-SAFE FUNCTION

If any malfunction is detected by the self-diagnostic function, ASC-ECU illuminates the ABS warning lamp, ASC warning lamp and brake warning lamp^*, and it disables ABS and EBD control.

note

*: The brake warning lamp is used as EBD control warning lamp.
