tion code
ABS ECU circuit is broken or short-cir-
cuited.
32
ABS motor is defective (ABS motor
stops and will not rotate).
33
ABS motor is defective (ABS motor
keeps rotating and will not stop).
34
Disconnection is detected in the ABS
ECU and hydraulic unit solenoid circuit.
35
Front wheel will not recover from the
locking tendency even though the sig-
nal is continuously transmitted from the
ABS ECU to release the hydraulic
51 pressure (when the battery voltage is
low).
Rear wheel will not recover from the
locking tendency even though the sig-
nal is continuously transmitted from the
ABS ECU to release the hydraulic
pressure (when the battery voltage is
52
low).
