Antilock General Description

WARNING: ABS VI cannot increase brake pressure above master cylinder pressure applied by the driver and cannot apply the brakes by itself.

NOTE: ABS operation is available from approximately 5 km/h (3 mph) to the maximum vehicle speed.

PURPOSE
ABS VI has been designed to improve the controllability and steerability of a vehicle during braking that would cause one or more wheels to lock.

OPERATION
ABS VI accomplishes this objective by controlling the hydraulic pressure applied to each wheel brake. Antilock braking occurs only when the stoplamp switch is closed and the Electronic Brake Control Module (EBCM) determines one or more wheels is about to lose traction during braking. The EBCM will then control the hydraulic modulator to change the brake pressures several times each second to keep the wheel(s) from locking and provide the driver with maximum vehicle controllability. The result is greatly improved braking, enabling the driver to more easily maintain steerability and to bring the vehicle to a controlled stop. ABS VI provides effective braking and directional control over a wide range of road surfaces and driving conditions.

The ABS power distribution system consists of fuses and the ignition switch. The fuses are ABS (5OA) located in fuse box 1; TAIL DOME (15A), STOP HORN (15A), IG-COIL METER (15A) and REAR DEFG (15A) are located in fuse block 2. Fuse box 1 is located on the RH side of the engine compartment, in front of the battery. Fuse block 2 is located under the LH side of the I/P.
