POWER SUPPLY TO CONTROL MODULE, NO DTCS STORED
KAA4F110
Circuit Description
Battery voltage is supplied to the electronic brake con-
trol module (EBCM) through fuse F19 and F29 in the
I/P fuse block, to terminal 50 and 1 of the EBCM
connector. The voltage is present when the ignition
switch is in ON or START.
Diagnosis
This test checks for battery output, proper grounding,
blown fuses, a faulty ignition switch, and problems in
the circuitry.
Cause(s)
The battery is defective.
There is a defective ground connection.
A connector is damaged.
A wire is broken or shorted.
A fuse is blown.
The ignition switch is malfunctioning.Fail Action
ABS action is disabled during the period of low voltage,
and the ABS warning lamp is ON for the remainder of
the ignition cycle.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. This step determines whether there is voltage at
the battery and the high current source.
7. This step checks for voltage at the ignition 1
source.
Diagnostic Aids
It is very important to perform a thorough inspection of
the wiring and the connectors. Failure to do so may re-
sult in misdiagnosis, causing part replacement with a
re-appearance of the malfunction.

4F-34 ABS AND TCS
ABS INDICATOR LAMP ILLUMINATED CONTINUOUSLY,
NO DTCS STORED
KAA4F120
Circuit Description
Battery voltage is supplied to the ABS warning lamp
with the ignition in ON or START. The warning lamp
should be activated only by the ABS control module
internally supplying ground to terminal 31.
Diagnosis
This procedure checks for a short to ground in the
wiring or a defective electronic brake control module
(EBCM).Cause(s)
There is a short to ground in the circuit between the
cluster terminal D7 and the EBCM terminal 31.
The EBCM is faulty.

SSANGYONG MY2002
4F-36 ABS AND TCS
SELF-DIAGNOSTICS
Important: The electronic brake control module (EBCM)
turns the valve relay off when a diagnostic trouble code
(DTC) is set. The scan tool will indicate that the valve
relay is off when it is used to monitor the data list. This
is normal and should not be considered a mal-function.
The EBCM performs system self-diagnostics and can
detect and often isolate system malfunctions. When it
detects a malfunction, the EBCM sets a DTC that repre
sents the malfunction, turns on the ABS and/or the
TCS indicators in most instances, and may disable the
ABS and/or the TCS functions, as necessary, for the
duration of the ignition cycle.
Once each ignition cycle, the EBCM performs an auto-
matic test when the vehicle reaches 2.75 km/h (1.7
mph). In the course of this test, the system cycles
each valve solenoid and the pump motor, along with
the necessary relays, to check component operation.
If the EBCM detects any malfunctions, it will set a
DTC as described above.
DISPLAYING DTCs
Tools Required
Scan Tool
DTCs can be read through the use of the scan tool.
CLEARING DTCs
Tools Required
Scan Tool
The diagnostic trouble codes (DTCs) in the electronic
brake control module (EBCM) memory are erased in
one of two ways:
Use the scan tool “Clear DTCs” selection.
 After 249 DTC-free ignition cycles.
These two methods are detailed below. Be sure to verify
the proper system operation and, the absence of DTCs
when the clearing procedure is completed.The EBCM will not permit DTC clearing until all DTCs
have been displayed. Also, DTCs cannot be cleared
by disconnecting the EBCM, disconnecting the battery
cables, or turning the ignition switch to LOCK.
Scan Tool Method
The scan tool can clear ABS/TCS system DTCs using
the mass storage cartridge.
1. Install the scan tool and the mass storage
cartridge.
2. Select “Fault Memory”.
3. Select “Clear Fault Memory”.
Clearing the fault memory cannot reset a valve relay
which was shut down when the fault was recognized.
Changes are possible only after the fault has been elimi-
nated and the next ignition cycle has begun.
Ignition Cycle Default
A DTC is erased from memory after 249 ignition cycles
without any reappearance of that malfunction.
INTERMITTENTS AND POOR
CONNECTIONS
As with most electronic systems, intermittent malfunc
tions may be difficult to diagnose accurately. The follow-
ing is a method to try to isolate an intermittent
malfunction, especially in wheel speed circuitry.
If an ABS malfunction occurs, the ABS indicator will
illuminate during the ignition cycle in which the
malfunction was detected. If it is an intermittent problem
which seems to have corrected itself (ABS indicator
OFF), a history DTC will be stored. Also stored will be
the history data of the DTC at the time the malfunction
occurred. Use the scan tool modular diagnostic system
to read ABS history data.
Most intermittents are caused by faulty electrical con
nections or wiring, although a sticking relay or solenoid
can occasionally be at fault.

DIAGNOSTIC TROUBLE CODE (DTC) 13/14
LEFT FRONT INLET AND OUTLET VALVE SOLENOID FAULT
KAA4F200
Circuit Description
The solenoid valve coil circuits are supplied with power
from the battery when the valve relay is energized.
Switched ground is provided by the electronic brake
control module (EBCM) to each coil.
Diagnosis
This procedure checks whether the left front inlet and
outlet valves are functioning.
Cause(s)
A valve has failed.
A solenoid coil is open or shorted.Fail Action
ABS is disabled, and the ABS warning lamp is turned
ON for the remainder of the ignition cycle. If the failure
is intermittent, the EBCM will enable the system at the
next ignition cycle and set a history DTC.
Test Description
The number(s) below refer to step(s) on the diagnostic
table.
1. This step begins the test of the inlet valve.
3. This step tests the outlet valve.
