ABS TROUBLESHOOTING INFORMATION

SYSTEM DESCRIPTION

SUMMARY OF ABS PRE-START SELF-DIAGNOSIS SYSTEM
The ABS pre-start self-diagnosis system diagnoses the electrical system as well as the operating status
of the modulator. When there is any abnormality, the problem and the problematic part can be detected
by outputting the problem code.
When the vehicle is running, pulse signals generated at the front wheel speed sensor and rear wheel
speed sensor/VS sensor are sent to the ABS control unit. When the ABS control unit detects that vehicle
speed goes to 5 km/h (3 mph), the pump motor is temporarily operated to check if the ABS system func-
tions normally. If the system is normal, pre-start self-diagnosis is complete by when the vehicle speed
goes to 5 km/h (3 mph) approximately.
If the ABS indicator blinks, because problem is detected during the pre-start self-diagnosis (page 16-7).
If the ABS indicator does not come on when the ignition switch is turned ON, or the ABS indicator stays
on after the pre-start self-diagnosis procedure is complete, the ABS indicator may be faulty. Follow the
troubleshooting (page 16-11).
