BRAKES 12-37
Anti-Lock Brake System
Pre-Diagnosis Inspection 2

Self-diagnosis Outline
  When the yellow ABS indicator light (LED) has blinked or come on, the ABS hydraulic unit memorizes
and stores the service code (19 codes including “Normal Code”) for the service person to troubleshoot
easily. The service code memory is powered directly by the battery and cannot be canceled by the
ignition switch.
  The ABS hydraulic unit can memorize up to 6 service codes. Further service codes are memorized
after erasing the preceding 6 service codes. If there is no fault, only the start code 12 is shown,
indicating that “The ABS is normal”.

Self-diagnosis Procedures
○When a problem occurs with the ABS system, the yellow
 ABS indicator light (LED) [A] lights.
                           NOTE
 ○Use a fully charged battery when conducting
  self-diagnosis. Otherwise, the light blinks very slowly
  or doesn’t blink.
 ○The motorcycle is stopped.
 ○Keep the self-diagnosis terminal grounded during self
  -diagnosis, with an auxiliary lead.
