ABS AND TCS 4F-5
SSANGYONG MY2002
EBD (ELECTRONIC BRAKE
FORCE DISTRIBUTION) SYSTEM
System Description
As an add-on logic to the ABS base algorithm, EBD
works in a range in which the intervention thresholds
for ABS control are not reached yet.
EBD ensures that the rear wheels are sensitively
monitored for slip with respect to the front axle. If slip
is detected, the inlet valves for the rear wheels are
switched to pressure hold to prevent a further increase
in pressure at the rear-wheel breaks, thus electronically
reproducing a pressure-reduction function at the rear-
wheel brakes.
ABS features an enhanced algorithm which includes
control of the brake force distribution between the front
and rear axles. This is called Electronic Brake
Distribution. In an unloading car condition the brake
efficiency is comparable to the conventional system
but for a fully loaden vehicle the efficiency of the EBD
system is higher due to the better use of rear axle
braking capability.
The Benefits of EBD
Elimination of conventional proportioning valve EBD
utilizes the existing rear axle wheel speed sensor
to monitor rear wheel slip.
Based on many variables in algorithm a pressure
hold, increase and/or decrease pulsetrain may be
triggered at the rear wheels insuring vehicle
stability.
Vehicle approaches the ideal brake force
distribution (front to rear).
Constant brake force distribution during vehicle
lifetime.
EBD function is monitored via ABS safety logic
(conventional proportioning valves are not
monitorable).
“Keep alive” function.Service Precautions
Observe the following general precautions during any
ABS/TCS service. Failure to adhere to these
precautions may result in ABS/TCS system damage.
1. Disconnect the EBCM harness connector before
performing the electric welding procedures.
2. Carefully note the routing of the ABS/TCS wiring
and wring components during removal. The ABS/
TCS components are extremely sensitive to EMI
(eletromagnetic interference). Proper mounting is
critical during component service.
3. Disconnect the EBCM connector with the ignition
OFF.
4. Do not hang the suspension components from the
wheel speed sensor cables. The cables may be
damaged.
5. Do not use petroleum based fluids in the master
cylinder. Do not use any containers previously used
for petroleum based fluids. Petroleum causes
swelling and distortion of the rubber components
in the hydraulic brake system, resulting in water
entering the system and lowering the fluid boiling
point.

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.

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-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.
