FAIL SAFE OPERATION
Anti-Lock Brake System -- Fail-Safe Chart |
- If there is a problem with any sensor signals or actuator systems, the skid control ECU prohibits the power supply to the brake actuator.
ABS control is prohibited, but EBD control continues as long as possible. If EBD control is impossible, the brake warning light comes on to warn the driver (RAV4_ACA30 RM000000ONI01MX.html).
- If system components have any malfunctions before starting control, the operation stops immediately. If system components have any malfunctions during control, the control stops gradually so as not to trigger a sudden change in vehicle conditions.
If it is impossible to control the systems, the warning light comes on to inform the driver of malfunctions in the systems (RAV4_ACA30 RM000000ONI01MX.html).
- HINT:
- If the anti-lock brake system malfunctions, the brake system operates normally without the anti-lock brake system.
- If the brake actuator malfunctions, a gradual loss of brake performance is expected, and anti-lock brake system control is prohibited.
