HOW TO PROCEED TROUBLE SHOOTING
The trouble or malfunction of the brake system mainly originates in the mechanical systems, such as the
brake pedal, brake booster, brake master cylinder, P valve, wheel cylinders and brake fluid line, or electri-
cal systems, such as the ABS actuator, wheel speed sensors, gravity sensor, ABS ECU and ABS related
wiring harness.
This manual describes mainly trouble shooting of the electrical system of the ABS control systems on the
premise that the brake mechanical systems are functioning normally.
Hence, when the brake system is encountered with any trouble, make sure that the trouble does not origi-
nate in the mechanical systems of the brake systems.
To proceed the trouble shooting, first perform the diagnosis check. Then, if any of the diagnosis codes
other than the normal codes is outputted, perform the trouble shooting according to the diagnosis codes.
When no diagnosis code is outputted even if malfunction phenomena exists, perform the trouble shooting
according to the malfunction phenomena.
The following diagram shows the basic procedure for the trouble shooting.
Actual approach may differ if you have much experience on this system. However, it is recommended to
perform the trouble shooting according to this procedure.
