Fail-Safe Functions (ASC-Ecu)
- When a malfunction is determined by the diagnostic function, ASC-ECU illuminates the brake warning light, brake warning display, ABS warning light, ABS warning display, ASC warning light, ASC warning display, and ASC OFF light. At the same time, ASC-ECU prohibits the EBD, ABS, ASC, TCL, brake assist, HSA, ESS and ACC/FCM.NOTE: The brake warning light and brake warning display are used as the EBD control warning light.
- When the brake pad temperature (assumed) exceeds the specified value, the ASC OFF light flashes (2 Hz).
