TROUBLE DIAGNOSIS FOR SELF-DIAGNOSTIC ITEMSPFP:00000
Wheel Sensor System EFS006LQ
INSPECTION PROCEDURE
1. CONNECTOR INSPECTION
Disconnect the ABS actuator and electric unit (control unit) connector E33 and wheel sensor of malfunctioning
code.
Check the terminals for deformation, disconnection, looseness or damage.
OK or NG
OK >> GO TO 2.
NG >> Repair or replace as necessary.
2. CHECK WHEEL SENSOR OUTPUT SIGNAL
1. Connect ABS active wheel sensor tester (J-45741) to wheel sensor using appropriate adapter.
2. 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.
3. 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.
Does the ABS active wheel sensor tester detect a signal?
YES >> GO TO 3.
NO >> Replace the wheel sensor. Refer to BRC-33, "
Removal and Installation" .
3. CHECK TIRES
Check for inflation pressure, wear and size of each tire. Refer to WT-29, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)" .
Are tire pressure and size correct and is tire wear within specifications?
YES >> GO TO 4.
NO >> Adjust tire pressure or replace tire(s).
4. CHECK WHEEL BEARINGS
Check wheel bearing axial end play. Refer to FAX-5, "
FRONT WHEEL BEARING INSPECTION" or RAX-4,
"REAR WHEEL BEARING INSPECTION" .
OK or NG
OK >> GO TO 5.
NG >> Repair or replace as necessary. Refer to FAX-5, "
Removal and Installation" or RAX-4, "Removal
and Installation" .

Preliminary CheckEES002F4
BASIC INSPECTION
1. CHECK ALL TIRE PRESSURES
Check all tire pressures. Refer to WT-29, "
Tire" .
OK or NG
OK >> GO TO 2.
NG >> Adjust tire pressure to specified value.
2. CHECK LOW TIRE PRESSURE WARNING LAMP ACTIVATION
Check low tire pressure warning lamp activation.
Does warning lamp activate for 1 second when ignition switch is turned ON?
YES >> GO TO 3.
NO >> GO TO WT-23, "
Low Tire Pressure Warning Lamp Does Not Come On When Ignition Switch Is
Tu rne d On." .
3. CHECK BCM CONNECTOR
1. Disconnect BCM harness connector.
2. Check terminals for damage or loose connection.
3. Reconnect harness connector.
OK or NG
OK >> GO TO 4.
NG >> Repair or replace damaged parts.
4. CHECK TRANSMITTER ACTIVATION TOOL
Check transmitter activation tool battery.
OK or NG
OK >> Carry out self-diagnosis.
NG >> Replace battery in transmitter activation tool.
Self-DiagnosisEES002F1
DESCRIPTION
During driving, the low tire pressure warning system receives the signal transmitted from the transmitter
installed in each wheel, and turns on the low tire pressure warning lamp when the tire pressure becomes low.
The control unit (BCM) for this system has pressure judgement and self-diagnosis functions.
FUNCTION
When the low tire pressure warning system detects low inflation pressure or an internal malfunction, the low
tire pressure warning lamp in the combination meter comes on. The malfunction location is indicated by the
low tire pressure warning lamp flashing and the buzzer sounding.
