4F – 54 ANTILOCK BRAKE SYSTEM

D17E305B

DIAGNOSTIC TROUBLE CODE (DTC) 0602

LEFT FRONT DUMP OPEN OR DRIVER SHORTED

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 open or
ground shorted).

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.
