About ABS BrakeScan
NOTE
ABS BrakeScan is the rst tool designed for Do-It-Yourselfers to access
the ABS diagnostic information. The Tool retrieves codes from the ABS
system and provides the denition of each code to help pinpoint the
problem areas within the Antilock Brake System that may have caused
the ABS light to turn on.

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
3
(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.
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 uid hydraulic pressure or that
the master cylinder is low on brake uid. 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 rst 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 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 uid 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 This 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.
