locking tendency even though the sig-
nal is continuously transmitted from
the ECU (ABS) to release the hydrau-
lic state (when the battery voltage is
41
normal).
Rear wheel will not recover from the
locking tendency even though the sig-
nal is continuously transmitted from
the ECU (ABS) to release the hydrau-
lic state (when the battery voltage is
42
normal).
Front wheel will not recover from the
locking tendency even though the sig-
nal is continuously transmitted from
the ECU (ABS) to release the hydrau-
lic state (when the battery voltage is
51
low).
Rear wheel will not recover from the
locking tendency even though the sig-
nal is continuously transmitted from
the ECU (ABS) to release the hydrau-
52
lic state (when the battery voltage is
low).
Present ECU (ABS) may be malfunctioning
