Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Fail-Safe Chart
- FAIL SAFE OPERATION
- If there is a problem with sensor signals or actuator systems, the skid control ECU prohibits power supply to the brake actuator assembly and terminate ABS control.
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 DIAGNOSIS SYSTEM ).
- If system components have any malfunction before starting control, immediately stop the operation. If system components have any malfunction during control, gradually stop the control 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 termination of the systems (See DIAGNOSIS SYSTEM ).
HINT:
- If the ABS system malfunctions, the brake system operates normally without the ABS system.
- If the brake booster encounters a malfunction, brake performance is gradually lost and ABS control is prohibited.
