Fail-Safe Chart

FAIL-SAFE CHART
1. FAIL SAFE OPERATION
^ When trouble occurs in the brake control system, the skid control ECU comes on the warning light on, displays a DTC corresponding to the malfunctioning systems on the multi information display, and prohibits ABS, BA, and VSC operations.
^ The skid control ECU prevents operation of a malfunctioning hydraulic pressure system and continues brake control with the normal hydraulic pressure system.

HINT:
^ If control of the ECB for any of the 4 wheels is prohibited, that wheel loses brake booster function or braking ability.
^ If one of the 4 wheels loses brake booster function, the feeling when depressing the brake pedal changes as the stroke simulator (pedal reactive force generating solenoid) operation will be prohibited.
^ If control of the ECB for all wheels is prohibited, the 2 front wheels will lose brake booster function.

ABS, EBD and BA System:

HINT: A malfunction in either the ABS or BA system will result in an identical operation, with ABS, BA, TRAC and VSC system control prohibited.





HINT: As for the TRAC and VSC systems, different systems prohibit different controls depending on a malfunctioning part.
