GENERAL DESCRIPTION AND SYSTEM OPERATION
BASIC KNOWLEDGE REQUIRED
Before using this section, it is important that you have
a basic knowledge of the following items. Without this
knowledge, it will be difficult to use the diagnostic
procedures contained in this section.
•Basic Electrical Circuits - You should understand
the basic theory of electricity and know the meaning
of voltage, current (amps), and resistance (ohms).
You should understand what happens in a circuit
with an open or shorted wire. You should be able to
read and understand a wiring diagram.
Use of Circuit Testing Tools - You should know
how to use a test light and how to bypass
components to test circuits using fused jumper
wires. You should be familiar with a digital
multimeter. You should be able to measure voltage,
resistance, and current, and be familiar with the
controls and how to use them correctly.
ABS SYSTEM COMPONENTS
The ABS 5.3 Antilock Braking System (ABS) consists
of a conventional hydraulic brake system plus antilock
components. The conventional brake system includes
a vacuum booster, master cylinder, front disc brakes,
rear disc brakes, interconnecting hydraulic brake pipes
and hoses, brake fluid level switch and the BRAKE
indicator.
The ABS components include a hydraulic unit, an elec-
tronic brake control module (EBCM), two system fuses,
four wheel speed sensors (one at each wheel), intercon-
necting wiring, the ABS indicator, the EBD indicator
and the TCS indicator. See “ABS Component Locator”
in this section for the general layout of this system.
The hydraulic unit with the attached EBCM is located
between the surge tank and the bulkhead on the left
side of the vehicle.
The basic hydraulic unit configuration consists of hy-
draulic check valves, two solenoid valves for each
wheel, a hydraulic pump, and two accumulators. The
hydraulic unit controls hydraulic pressure to the front
calipers and rear calipers by modulating hydraulic
pressure to prevent wheel lockup.
Units equipped with TCS add two more valves for each
drive wheel for the purpose of applying the brake to a
wheel that is slipping. This is done with pressure from
the hydraulic pump in the unit. There is also a TCS
indicator lamp on the instrument panel to alert the driver
to the fact that the TCS system is active. The
components identified in the drawing are those added
to the basic ABS 5.3 system to provide traction control.
Nothing in the hydraulic unit or the EBCM is serviceable.
In the event of any failure, the entire ABS unit withattached EBCM must be replaced. For more
information, refer to “Base Braking Mode” and
“Antilock Braking Mode” in this section.
TRACTION CONTROL SYSTEM
(TCS) DESCRIPTION
General Information
The traction control system (TCS) is a traction system
by means of brake intervention only, available in a low
speed range (< 60kph).
It workes on µ - split roads with sidewise different friction
coefficients.
The spinning driven wheel is braked and the drive
torque can be transferred to the wheel on the high-µ
side. During TCS active, the TCS information lamp is
blinking.
The temperature of the brakes is calculated by a mathe-
matical model and TCS is switched passive if the calcu-
lated temperature is greater than a threshold value (500
°C).
TCS is permitted again, when the calculated tempera-
ture is less than 350 °C.
Control Algorithm
The input signals for the control algorithm are the
filtered wheel speed signals from the ABS speed
processing.
With the speed difference of the driven wheels, the
control deviation is calculated.
If the control deviation exceeds a certain threshold
value, the wheel with the greater slip is braked actively.
The threshold value depends on the vehicle speed:
It is reduced with increasing vehicle speed down to a
constant value.

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.
