FAIL-SAFE CHART
1. FAIL-SAFE OPERATION
The brake actuator assembly turns off each solenoid and the ECM shuts off VSC control (traction control signal) from the skid control ECU accordingly, which turns out to be as if the ABS, TRAC and VSC systems were not installed.
The ABS control will be prohibited, but EBD control will continue as
much as possible. If EBD control is impossible, the brake warning light
will come on to warn the driver (See page
).
If it is impossible to control the systems, the warning light comes on
to inform the driver of termination of the systems (See page
).
Malfunction Area |
Control Method |
---|---|
ABS system |
ABS, BA, TRAC and VSC control prohibited |
BA system |
ABS, BA, TRAC and VSC control prohibited |
EBD system |
ABS, EBD, BA, TRAC and VSC control prohibited |
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.
TRAC and VSC System
Malfunction Area |
Control Method |
---|---|
Engine control system (TRAC and VSC systems) |
Before control: Disables control During control: Uses only the brakes to effect control |
Brake control system (VSC system) |
Before control: Disables control During control: Uses only the engine to effect control |
Brake control system (TRAC system) |
Before control: Disables control During control: Disables control (by gradually ending control) |
HINT:
As for the TRAC and VSC systems, different systems prohibit different controls depending on a malfunctioning part.
