4F–52 ANTILOCK BRAKE SYSTEM
DAEWOO M-150 BL2
D17E305B
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.
