FAIL-SAFE CHART
The brake actuator assembly turns off the solenoids and the ECM stops its VSC control according to signals from the skid control ECU. The vehicle will operate in a manner similar to a vehicle that is not equipped with ABS, TRAC and VSC systems.
ABS control will be prohibited, but EBD control will continue to the
extent that EBD control is possible. If EBD control is impossible, the brake
warning light will come on to warn the driver (See page
).
If a system component malfunctions during VSC control, the system will gradually stop performing control so as not to trigger a sudden change in vehicle operation.
If it is impossible for control to continue, the warning light comes
on to inform the driver of system control termination (See page
).

Freeze Frame DataHigh Power Supply Voltage Malfunction (C1417)
DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU
(brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS
operation.
This DTC is stored when the +BS terminal voltage deviates from the DTC detection
condition due to a malfunc ...
