Fail-Safe Functions

When a malfunction is determined by the diagnostic function, ASC-ECU illuminates the ABS warning light, ABS warning display, brake warning display, brake warning light *, ASC warning display, and ASC OFF display. At the same time, ASC-ECU prohibits the ABS, EBD, stability control, and TCL control.

NOTE: *: The brake warning light and brake warning display are used as the EBD control warning light.

Illumination condition of warning light and display in case of failure
