HINT:

• The yaw rate sensor and deceleration sensor are combined and in a single unit. This unit communicates with the skid control ECU through the CAN communication system.

• No changes have been made to the communication method between the VSC system and ECM. However, the communication method between the Translate ECU and ECM has been changed from serial to CAN communication.

a. ABS (Anti-lock Brake System)

2007 BRAKES Brake Control - Sequoia

The ABS helps prevent the wheels from locking when the brakes are applied firmly or when braking on a slippery surface.

b. EBD (Electronic Brake force Distribution)

The EBD control utilizes ABS, realizing proper brake force distribution between front and rear wheels in accordance with driving conditions.

In addition, during braking while cornering, it also controls the brake forces of the right and left wheels, helping to maintain vehicle behavior.

c. BA (Brake Assist)

The primary purpose of the brake assist system is to provide an auxiliary brake force to assist the driver who cannot generate a large enough brake force during emergency braking, thus helping to maximize the vehicle's braking performance.

d. TRAC (Traction Control)

The TRAC system helps prevent the drive wheels from slipping if the driver presses down on the accelerator pedal excessively when starting off or accelerating on a slippery surface.

e. 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.
