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 “Rear Wheel Speed Sensor” in this sec-
tion.

Important: Wheel speed sensor intermittent malfunc-
tions may be difficult to locate. Take care not to disturb
any electrical connections before performing an indi-
cated step of this table. That will ensure that an intermit-
tent connection will not be corrected before the source
of the malfunction is found.

DIAGNOSTIC TROUBLE CODE (DTC) 0601

LEFT FRONT DUMP SHORTED OR DRIVER OPEN

Circuit Description

EBCM proceeds the self–test about the dump valve or
the motor driver, if the EBCM senses the brake signal.

Diagnosis

If the EBCM proceeds the self–test about the dump
valve or the motor driver and senses the fault, the
EBCM may make the fault code.

Cause(s)

EBCM internal fault (Left front dump voltage shorted
or ground open).

Warning Lamp Operation

ABS warning lamp ON.

ABS warning lamp OFF if the ignition switch ON/OFF.

Fail Action

This is a critical operational fault. The ABS is disabled
and the ABS warning lamp is turned on. The proportion-
ing is operation.
