ANTI-LOCK BRAKE SYSTEM (ABS)

SERVICE INFORMATION

GENERAL
The ABS control module may be damaged if dropped. Also, if the connector is disconnected when current is flowing, the
excessive voltage may damage the control module. Always turn the ignition switch OFF before servicing.
• This section covers service of the Anti-lock Brake System (ABS). For conventional brake service (page 15-4).
• When the motorcycle is running and the front wheel leaves the ground for a long time (wheelies), the ABS control unit
(ECU) detects difference of the front and rear wheel speeds and then the indicator blinks.
• When the ABS control unit (ECU) detects a problem, it stops the ABS function and switches back to the conventional
brake operation, and the ABS indicator blinks or stays on. Take care during the test ride.
• Troubles not resulting from a faulty ABS (e.g. brake disc squeak, unevenly worn brake pad) cannot be recognized by the
ABS diagnosis system.
• Read "ABS Troubleshooting information" carefully, inspect and troubleshoot the ABS according to the Diagnostic Trou-
bleshooting. Observe each step of the procedures one by one. Write down the problem code and probable faulty part
before starting diagnosis and troubleshooting.
• After troubleshooting, erase the problem code and perform the pre-start self-diagnosis to be sure that the ABS indicator
is operating normally.
• When the wheel speed sensor and/or pulser ring is replaced, check the clearance (air gap) between both components.
• The ABS control unit (ECU) is mounted on the modulator (the modulator with the built-in ECU). Do not disassemble the
ABS modulator. Replace the ABS modulator as an assembly when it is faulty.
• The ABS modulator may be damaged if dropped. Also if a connector is disconnected when current is flowing, the exces-
sive voltage may damage the control unit. Always turn off the ignition switch before servicing.
• Be careful not to damage the wheel speed sensor and pulser ring when removing and installing the wheel.
• The VS sensor is used for the PGM-FI system and also used as rear wheel speed sensor for the ABS.
• The following color codes are used throughout this section.
Bu = Blue G = Green
