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.
System Description
- SYSTEM DESCRIPTION
- ABS (Anti-lock Brake System)
The ABS helps prevent the wheels from locking when the brakes are applied firmly or when braking on a slippery surface.
- EBD (Electronic Brake Force Distribution) The EBD control utilizes the ABS, realizing the proper brake force distribution between the front and rear wheels in accordance with the driving conditions.
In addition, during cornering and braking, it also controls the brake forces of the right and left wheels, helping to maintain the vehicle balance.
- BA (Brake Assist)
The primary purpose of the brake assist system is to provide an auxiliary brake force to assist a driver who cannot generate a large brake force during emergency braking, thus helping improve the vehicle's brake performance.
- TRAC (Traction Control)
The TRAC system helps prevent the drive wheels from slipping if the driver depresses the accelerator pedal excessively when starting off or accelerating on a slippery surface.
- VSC (Vehicle Stability Control)
The VSC system helps prevent the vehicle from slipping sideways as a result of strong front wheel skid or strong rear wheel skid during cornering.
- ABS (Anti-lock Brake System)
- ABS WITH EBD & BA & TRAC & VSC OPERATION
- The skid control ECU calculates vehicle stability tendency based on the signal of the speed sensor, yaw rate sensor and steering angle sensor. The ECU judges whether the control of engine output torque by the electronic control throttle and wheel brake pressure by the brake actuator can start based on the calculation results.
- The SLIP indicator light blinks and the skid control buzzer sounds to inform the driver that the VSC system is operating. The SLIP indicator light also blinks when TRAC is operating, and the operation being performed is displayed.
- FAIL-SAFE FUNCTION
- When a failure occurs in the ABS & BA & TRAC & VSC systems, the ABS warning light turns on and the ABS & BA & TRAC & VSC operations are prohibited. In addition to this, when there is a failure that disables the EBD operation, the brake warning light also turns on and the EBD operation is prohibited. If a control is prohibited due to a malfunction during its operation, the control will be cut off gradually so that vehicle stability will not change suddenly.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
