Section 2 – Getting Started
Introduction
ABS BrakeScan is the first tool designed for Do-It-Yourselfers to access the
ABS diagnostic information. The Tool retrieves codes from the ABS system and
provides the definition of each code to help pinpoint the problem areas within
the Antilock Brake System that may have caused the ABS light to turn on.
The Tool was developed by experts in the automotive service industry to access
the information stored in the ABS module.
All information, illustrations and specifications contained in this manual are
based on the latest information available from industry sources at the time of
publication. No warranty (expressed or implied) can be made for its accuracy
or completeness, nor is any responsibility assumed by the manufacturer or
anyone connected with it for loss or damages suffered through reliance on any
information contained in this manual or misuse of accompanying product. The
manufacturer reserves the right to make changes at any time to this manual or
accompanying product without obligation to notify any person or organization
of such changes.
ABS Overview
Anti-Lock Brake Systems (ABS) began being used on vehicles in the
mid-1980's. The mechanical components of the hydraulic-brake system
(master cylinder, shoes, pads, wheel cylinders, calipers, rotors, drums, and
assorted hardware) work the same as they did before ABS. What has changed,
however, is the addition of an ABS computer module, wheel speed sensors, and
a hydraulic control unit consisting of solenoid valves.
How ABS works
When the brake pedal is pressed with normal force, the vehicle decelerates. If,
during deceleration, the ABS computer detects wheels going at different
speeds (wheels slipping) from data provided by the wheel speed sensors, then
the vehicle enters antilock mode. During antilock mode, the ABS computer will
control brake fluid hydraulic pressure delivered to the wheels. The brake fluid
hydraulic pressure will be equal to or less than the value delivered by the master
cylinder. By controlling pressure to the wheels, the ABS computer can prevent
one wheel from locking up while others keep turning. It can also prevent wheels
from turning at different rates, so the vehicle should stop in a straight line.
ABS Configurations
ABS has had three different configurations for distribution of wheel speed
sensors and hydraulic lines from the hydraulic control unit since its conception:
• The earliest ABS configuration used one wheel speed sensor that monitor
the speed of both rear wheels. If the rear wheels would lock up, the ABS
computer would pulse a solenoid in the hydraulic control unit, which would
then change the brake fluid hydraulic pressure applied to the rear wheels.
• The next evolution in ABS added wheel speed sensors to both front
wheels, while still having a single wheel speed sensor in the rear to monitor
••••••••••••••••••••••••••••••••••••••••••••••••••••••••• 2–1

Getting Started
both rear wheels. Under this system, if the left front, right front, or both rear
wheels rotate at a speed different from each other, the ABS computer could
use up to three separate solenoids to control brake fluid hydraulic pressure.
This allowed the ABS system to control the left front, right front, and both
rear wheels together independently.
• Today, some vehicles have one wheel speed sensor per wheel for a total of
four. On these vehicles, the ABS computer can independently control brake
fluid hydraulic pressure on every wheel.
2
ABS Malfunction Indicator Lamp (MIL)
The dashboard or instrument panel of your vehicle contains a light labeled
something similar to ABS, or Anti-Lock, if the vehicle is ABS equipped. Some
vehicles will also have a light marked BRAKE. This light usually indicates a loss
of brake fluid hydraulic pressure or that the master cylinder is low on brake fluid.
Refer to your owner's manual for a description of the lights in your vehicle. Each
time your vehicle is started, the ABS computer performs a self-test called a
Drive Cycle during the first acceleration to make sure the ABS components are
working correctly. If the ABS computer detects a malfunction at completion of
the Drive Cycle, ABS will turn on the ABS MIL. When the ABS MIL is on, a
Diagnostic Trouble Code (DTC) is stored in the ABS computer. Once a repair
has been successfully made, the ABS computer, on most vehicles,
should turn off the ABS MIL at completion of the next Drive Cycle.
ABS Repair Tips
• Before servicing your ABS, refer to the manufacturer's recommendations.
• Torque the wheel lug nuts properly to avoid bending a rotor or drum, which
can cause inaccurate wheel speed sensor readings.
• Bleed the brake system properly.
• Always add fresh brake fluid to the master cylinder.
• Always replace tires with the manufacturer's recommended size.
• Always rotate tires as recommended by manufacturer.
• When interpreting DTCs retrieved from the vehicle, always follow the manufacturer's recommendations for repair.
! WARNING
The Tool may not detect every malfunction. Do not take
chances with brakes, steering, or other vital functions of
your vehicle, as a serious accident could result. Always
follow vehicle manufacturer’s warnings, cautions, and
service procedures.

❒
current code may have just occurred or may have been present over
time.
History - A DTC with a History designation is one that has been detected
by the anti-lock brake control module over a span of time. It is a current
failure that has been present long enough to be stored in long-term
memory.
CURR/HIST - A CURR/HIST DTC indicates that a failure is both current
and historical as defined above.
Intermittent - An intermittent status indicates that the DTC has appeared
intermittently since the anti-lock brake control module was reset. (Control
modules are reset by mechanics after a repair has been completed.)
MIL Code - Indicates that the ABS Computer is reporting that the ABS
Malfunction Indicator Light is on. If MIL Code is displayed by the Tool, but
the vehicle dashboard does not display the ABS MIL, then you have a
potential problem with the circuit that controls the ABS MIL, the bulb
itself, a fuse, or the electrical system.
This code indicates that you currently
have a problem with the Left Front
Wheel Speed Sensor Circuit and that
the problem is illuminating the ABS
malfunction indicator lamp (MIL) on
the dashboard.

Error Messages
Check the following if an error message displays:
❒ Verify ignition key is in the ON and not in the ACCESSORIES position.
❒ Make sure Vehicle Diagnostics Cable is attached to vehicle’s data link
connector (DLC) and Tool.
❒ Look at DLC and check for cracked or recessed pins, or for any
substance that could prevent a good electrical connection.
❒ Test for continuity between the DLC wiring and the vehicle computers. In
an extreme case, there may be a broken wire.
❒ Check for bent or broken pins.
❒ With the key on engine off (KOEO), check for blown fuses.
❒ Make sure the vehicle’s control module has a good ground. If the
❒
❒
computer case for the vehicle is grounded, then clean the connection
and apply a conductive (dielectric) grease to the mating surfaces.
With the KOEO, verify battery voltage is at least 8.0V.
Verify the control module is not defective. Refer to the service manual to
diagnose the control module.
Tool Does Not Power Up
Review Safety Precautions before troubleshooting. If Tool will not
power up, communicate with vehicle’s control module, pass Tool
self-tests, or functions incorrectly in any other way, do the following:
❒
