DIAGNOSTIC TROUBLE CODE (DTC) 0356

LEFT FRONT WHEEL SPEED SENSOR CIRCUIT

INTERMITTENT SHORTED

Circuit Description

As a toothed ring passes by the wheel speed sensor,
changes in the electromagnetic field cause the wheel
speed sensor to produce a sinusoidal (AC) voltage sig-
nal whose frequency is proportional to the wheel speed.
The magnitude of this signal is directly related to wheel
speed and the proximity of the wheel speed sensor to
the toothed ring often referred to as the air gap.

Diagnosis

This test intermittent the left front wheel speed sensor
circuit.

Cause(s)

The wheel speed sensor is intermittent shorted to the
battery or ground.

There is a loose connection in the wheel speed sen-
sor circuit.

There is a loose connection in the EBCM.

The EBCM is malfunctioning.

Fail Action

This is a critical operational fault. The ABS is disabled
and the ABS warning lamp repeat intermittent turned on,
and off. The proportioning is operation.

Diagnostic Aids

An ‘‘intermittent’’ malfunction may be caused by a poor
connection, rubbed through wire insulation, or a wire
that is broken inside the insulation.

Thoroughly check any circuitry suspected of causing the
intermittent complaint. Look for backed out terminals,
improper mating, broken locks, improperly formed or
damaged terminals, poor terminal to wiring connections,
or physical damage to the wiring harness.

Wheel speed sensor resistance will increase as the sen-
sor temperature increases.

When replacing a wheel speed sensor, inspect the sen-
sor terminals and harness connector for corrosion and/
or water intrusion. If evidence of corrosion or water

ANTILOCK BRAKE SYSTEM 4F – 23

intrusion exists, replace the wheel speed sensor har-
ness. If replacing a wheel speed sensor harness, in-
spect the sensor terminals. If you find evidence of
corrosion or water intrusion, replace the wheel speed
sensor. Refer to “Front Wheel Speed Sensor” in this
section.

tions may be difficult to locate. Take care not to disturb
