ABS Service Codes
Power Supply Voltage Inspection (Over-Voltage)
(Service Code B53)
• Check  the charging voltage (see Charging Voltage In-
  spection(16-36)).
    If the charging voltage is good, perform the Pre-Diagnosis
    Inspection 1 and 2 (see Inquiries to Rider(12-40)).
    If this service code appears even if all checks are ended,
    replace the ABS hydraulic unit.
    If the service code does not appear, the ABS system nor-
    mal (temporary failure).
ECU Inspection (Service Code B55)
○This ECU is built in the ABS hydraulic unit. Therefore the
    ECU cannot be checked directly.
•   Perform the Pre-Diagnosis Inspection 1 and 2 (see In-
    quiries to Rider(12-40)).
    If this service code appears even if all checks are ended,
