41
mal).
Rear wheel will not recover from the locking
tendency even though the signal is continuously
transmitted from the ECU (ABS) to release the
hydraulic state (when the battery voltage is nor-
42
mal).
Front wheel will not recover from the locking
tendency even though the signal is continuously
transmitted from the ECU (ABS) to release the
hydraulic state (when the battery voltage is
51
low).
Rear wheel will not recover from the locking
tendency even though the signal is continuously
transmitted from the ECU (ABS) to release the
