ACTIVE STABILITY CONTROL SYSTEM (ASC)

35C-10

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.
