LEFT REAR WHEEL SPEED SENSOR SIGNAL
RIGHT FRONT WHEEL SPEED SENSOR SIGNAL
RIGHT REAR WHEEL SPEED SENSOR SIGNAL
WHEEL SPEED SENSOR SIGNAL ERROR

Test Note:

All symptoms listed above are diagnosed using the same tests.

The title for the tests will be LEFT FRONT WHEEL SPEED
SENSOR SIGNAL.

When Monitored and Set Condition:

LEFT FRONT WHEEL SPEED SENSOR SIGNAL

When Monitored:

Ignition On - Continuously

Set Condition:

When the value of the wheel speed sensor signal is missing at vehicle

speeds over 40 km/h (25 mph) OR during a start-up test with vehicle speeds over 12km/h
(8 mph) OR the vehicle is accelerated by 18 km/h (12 mph) after a wheel speed sensor
signal has been lost.

POSSIBLE CAUSES

INTERMITTENT WHEEL SPEED SENSOR SIGNAL DTC

DAMAGED SENSOR/CAB HARNESS CONNECTOR

DAMAGED WHEEL SPEED SENSOR TONE WHEEL

EXCESSIVE WHEEL SPEED SENSOR AIR GAP

DAMAGED WHEEL BEARING

DAMAGED BRAKE LININGS/COMPONENTS

WHEEL SPEED SENSOR FAILURE

ANTI-LOCK BRAKE CONTROLLER

TEST

ACTION

APPLICABILITY

NOTE: Refer to the symptom list and repair any WHEEL SPEED SENSOR
CIRCUIT DTCs before continuing.
Turn the ignition on.
With the DRBIII

t in Sensors, monitor ALL the Wheel Speed Sensor signals while an

assistant drives the vehicle.
Slowly accelerate from a stop to 65 km/h (40 mph).
NOTE: Wheel Speed should not vary by more than 10% from wheel to wheel
when driving in a straight line.
Do any of the Wheel Speed Sensor signals vary by greater than 10% while driving in
a straight line?

All

Yes

→ Go To 2

→ Go To 8
