FAIL-SAFE CHART
FAIL-SAFE OPERATION
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, VSC and brake hold 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 system warning light (red indicator) will come on to warn the driver.
