ABS (ANTI-LOCK BRAKE SYSTEM)
8-96
TIP
The ABS performs a self-diagnosis test for a few seconds each time the vehicle first starts off after the
main switch was set to “ON”. During this test, a “clicking” noise can be heard from under the rider seat,
and if the brake lever or brake pedal are even slightly applied, a vibration can be felt at the lever and
pedal, but these do not indicate a malfunction.
Special precautions for handling and servicing a vehicle equipped with ABS
NOTICE
ECA23P1050
Care should be taken not to damage components by subjecting them to shocks or pulling on
them with too much force since the ABS components are precisely adjusted.
• The ABS ECU and hydraulic unit are a united assembly and cannot be disassembled.
• The malfunction history is stored in the memory of the ABS ECU. Delete the fault codes when the ser-
vice is finished. (This is because the past fault codes will be indicated again if another malfunction
occurs.)

[A] Malfunction check using the ABS warning light
[B] Detailed check of the malfunction
The results of the self-diagnosis by the ABS ECU can be indicated using the ABS warning light flash
pattern.
[C] Determining the cause and location of the malfunction
Determine the cause of the malfunction from the condition and place where the malfunction occurred.
[D] Servicing the ABS
Execute the final check after disassembly and assembly.
Self-diagnosis using the ABS ECU
The ABS ECU performs a static check of the entire system when the main switch is set to “ON”. It
also checks for malfunctions while the vehicle is ridden. Since all malfunctions are recorded after
they are detected, it is possible to check the recorded malfunction data using the ABS warning
light flash pattern when the ABS ECU has entered the self-diagnosis mode.
