ANTI-LOCK BRAKE SYSTEM {ABS)
BEFORE STARTING TROUBLESHOOTING
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 approximately 10 km/h (6 mph) or more, the wheel speed sensor signal is sent to the ABS control unit
(ECU), then the ABS pre-start self-diagnosis system operates the control motor on the modulator, checks the crank angle
condition with the ABS control unit and this detects whether the modulator operation is normal, and it completes the pre-
start self-diagnosis.
When the ABS is normal, the ABS indicator goes off just after a road speed of 10 km/h (6 mph) indicating that the diagnosis
is completed.
If a problem is detected, the ABS indicator blinks or comes on and stays on to notify the rider of the problem. The self-diag-
nosis is also made while the motorcycle is run ning, and the indicator blinks when a problem is detected.
When the indicator blinks, the cause of the problem can be identified by retrieving the problem code following the speci-
fied retrieval procedure (page 16-5).
