REMOVAL

Be careful with the following when removing sensor.

CAUTION:

• Never twist sensor harness as much as possible, when removing it. Pull sensors out without pulling

sensor harness.

• Be careful to avoid damaging sensor edges or rotor teeth. Remove wheel sensor first before remov-

ing front or rear wheel hub. This is to avoid damage to sensor wiring and loss of sensor function.

• When you see the harness of the wheel sensor from the front side of the vehicle ensure that the

white lines (B) are not twisted.

INSTALLATION

Be careful with the following when installing wheel sensor. Tighten installation bolts to the specified torques.
• When installing, make sure there is no foreign material such as iron chips on and in the mounting hole of the

wheel sensor. Make sure no foreign material has been caught in the sensor rotor. Remove any foreign mate-
rial and clean the mount.

DIAGNOSIS AND REPAIR WORKFLOW

NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and alternator test segments must be done
as a set from start to finish.

1.

PRELIMINARY INSPECTION

Perform the preliminary inspection. Refer to 

CHG-24, "Inspection Procedure"

.

>> GO TO 2.

2.

STOP POWER GENERATION VOLTAGE VARIABLE CONTROL SYSTEM

Stop the operation of the power generation voltage variable control in either of the following procedures.
• After selecting “ENGINE” of “SELECT SYSTEM” using CONSULT-III, set the DUTY value of “ALTERNATOR

DUTY” to 0 % by selecting “ALTERNATOR DUTY” of “Active Test”. Continue “Active Test” until the end of
inspection. (When the DUTY value is 0 or 100 %, the normal power generation is performed according to the
characteristic of the IC voltage regulator of the alternator.)

• Turn the ignition switch OFF, and disconnect the battery current sensor connector. [However, DTC (P1550 -

P1554) of the engine might remain. After finishing the inspection, connect the battery current sensor connec-
tor and erase the self-diagnostic results history of the engine using CONSULT-III.]

>> GO TO 3.

3.

DIAGNOSIS WITH STARTING/CHARGING SYSTEM TESTER

Perform the charging system test using Starting/Charging System Tester (SST: J-44373). For details and oper-
ating instructions, refer to Technical Service Bulletin.

Test result

CHARGING SYSTEM NORMAL>>Charging system is normal and will also show “DIODE RIPPLE” test

result.

NO CHARGING VOLTAGE>>GO TO 4.
LOW CHARGING VOLTAGE>>GO TO 12.
HIGH CHARGING VOLTAGE>>GO TO 14.
DIODE RIPPLE NORMAL>>Diode ripple is OK and will also show “CHARGING VOLTAGE” test result.
EXCESS RIPPLE DETECTED>>Replace the alternator. Perform “DIODE RIPPLE” test again using Starting/

Charging System Tester (SST: J-44373) to confirm repair.

DIODE RIPPLE NOT DETECTED>>GO TO 4.

4.

INSPECTION WITH CHARGE WARNING LAMP (IGNITION SWITCH IS ON)

Turn the ignition switch ON.

Does the charge warning lamp illuminate?

YES

>> GO TO 6.

NO

>> GO TO 5.

5.

“L” TERMINAL CIRCUIT (OPEN) INSPECTION

Check “L” terminal circuit (open). Refer to 

CHG-11, "Diagnosis Procedure"

.

Is the “L” terminal circuit normal?

YES

>> Replace alternator.

NO

>> Repair as needed.

6.

INSPECTION WITH CHARGE WARNING LAMP (IDLING)

Start the engine and run it at idle.

Does the charge warning lamp turn OFF?

YES

>> GO TO 9.

NO

>> GO TO 7.

7.

“L” TERMINAL CIRCUIT (SHORT) INSPECTION

Check “L” terminal circuit (short). Refer to 

CHG-13, "Diagnosis Procedure"

.

Is the “L” terminal circuit normal?

YES

>> GO TO 8.

NO

>> Repair as needed.
