DTC TABLE OF ABS
*1 It goes off after running at more than 5 km/h (3.1 mile/h).
*2 The wheel speed sensor lead wire is connected to the ABS control unit, but a short-circuit or faulty conti-
nuity inside the ABS control unit caused this DTC to appear, therefore, the ABS control unit/HU assembly
must be replaced. An insufficient wheel speed sensor output voltage is the cause of a malfunction in
which the ABS is activated even if the brakes are not suddenly applied. If this occurs frequently even
though the wheel speed sensor is operating correctly, the ABS control unit/HU assembly should be
replaced.
*3 When the voltage resumes the normal level, the ABS indicator light will go off.
*4 There are times that the ABS indicator light does not light up.

When disconnecting couplers and turning the ignition switch to ON, disconnect the ABS con-
trol unit coupler in order to prevent a DTC from being stored. Each time a resistance is mea-
sured, the ignition switch should be set to OFF.
