SELF-DIAGNOSTIC FUNCTION AND DIAGNOSTIC CODE TABLE
41 Front wheel ABS (intermit-
tent wheel speed pulses or
incorrect depressuriza-
tion)
• Pulses from the front
wheel sensor are re-
ceived intermittently
while the vehicle is trav-
eling.
• Front wheel will not re-
cover from the locking
tendency even though
the signal is transmitted
from the ABS ECU to re-
duce the hydraulic pres-
sure.
• Incorrect installation of
the front wheel sensor
• Incorrect rotation of the
front wheel
• Front brake dragging
• Defective hydraulic unit
assembly

Rear wheel ABS (intermit-
tent wheel speed pulses or
incorrect depressuriza-
tion)
• Pulses from the rear
wheel sensor are re-
ceived intermittently
while the vehicle is trav-
eling. (for DTC No. 42)
• Rear wheel will not re-
cover from the locking
tendency even though
the signal is transmitted
from the ABS ECU to re-
duce the hydraulic pres-
sure.
• Incorrect installation of
the rear wheel sensor
(for DTC No. 42)
• Incorrect rotation of the
rear wheel
• Rear brake dragging
• Defective hydraulic unit
assembly

incorrect installation of
the rotor
• Defective front wheel
sensor or incorrect in-
stallation of the sensor
