DTC CONFIRMATION PROCEDURE
1.CHECK SELF DIAGNOSTIC RESULT
With CONSULT.
- Start engine and drive vehicle at approximately 21 km/h (13 MPH)
or more for approximately 5 minutes.
- Perform self diagnostic result.
Diagnosis Procedure
CAUTION:
Do not check between wheel sensor terminals.
1.CONFIRM DTC
With CONSULT
- Perform self-diagnostic result of ABS and record all active DTCs.
- Clear all DTCs.
- Perform DTC confirmation procedure.
2.INSPECT WHEEL SENSOR
Inspect the suspect wheel sensor for damage or deformation.
3.HARNESS AND CONNECTOR INSPECTION
- Disconnect ABS actuator and electric unit (control unit) connector
E26 and wheel sensor connector of
suspect wheel.
- Check harness, connectors and terminals for corrosion,
deformation, disconnection, looseness or damage.
4.CHECK WHEEL SENSOR OUTPUT SIGNAL
- Connect ABS active wheel sensor tester (J-45741) to wheel sensor
using appropriate adapter.
- Turn on the ABS active wheel sensor tester power switch.
NOTE:
The green POWER indicator should illuminate. If the POWER indicator does not
illuminate, replace the
battery in the ABS active wheel sensor tester before proceeding.
- Spin the wheel of the vehicle by hand and observe the red SENSOR
indicator on the ABS active wheel
sensor tester. The red SENSOR indicator should flash on and off to indicate
an output signal.
NOTE:
If the red SENSOR indicator illuminates but does not flash, reverse the
polarity of the tester leads and
retest.
5.CHECK WIRING HARNESS FOR SHORT TO VOLTAGE
- Turn ignition switch ON.
- Check voltage between wheel sensor harness connector terminals of
suspect wheel and ground.

6.CHECK WIRING HARNESS FOR SHORT TO GROUND
- Turn ignition switch OFF.
- Check continuity between wheel sensor harness connector terminals
of suspect wheel and ground.


7.CHECK WIRING HARNESS FOR SHORT BETWEEN CIRCUITS
Check continuity between wheel sensor harness connector terminals of suspect
wheel.

8.CHECK WIRING HARNESS FOR OPEN CIRCUIT
Check continuity between ABS actuator and electric unit (control unit)
connector E26 and wheel sensor connector
of wheel with DTC.

9.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) POWER SUPPLY CIRCUIT
- Turn ignition switch ON.
- Check voltage between ABS actuator and electric unit (control
unit) harness connector E26 terminal and
ground.

10.CHECK ABS ACTUATOR AND ELECTRIC UNIT (CONTROL UNIT) GROUND CIRCUIT
- Turn ignition switch OFF.
- Check continuity between ABS actuator and electric unit (control
unit) connector E26 terminals and
ground.

11.CHECK WHEEL SENSOR INPUT VOLTAGE
- Connect ABS actuator and electric unit (control unit) connector
E26.
- Turn ignition switch ON.
- Check voltage between suspect wheel sensor harness connector
terminals.

12.CONFIRM REPAIR
With CONSULT
- Clear all DTCs.
- Perform DTC confirmation procedure.
