ABS: 4E-34
*
1
: It goes off after running at more than 10 km/h (6.2 mile/h).
*
2
: The wheel speed sensor lead wire is connected to the ABS control unit, but a short-circuit or faulty continuity 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.
CAUTION
!
When disconnecting couplers and turning the ignition switch ON, disconnect the ABS control unit
coupler in order to prevent a DTC from being stored. Each time a resistance is measured, the ignition
switch should be set to OFF.
