ANTI-LOCK BRAKE SYSTEM (ABS) 1 1
TROUBLESHOOTING
Precaution
Conditions that are not malfunctions
1. It may happen that vibration is felt in the steering wheel, body, and/or brake pedal when the ABS
is functioning; such vibration is simply an indication that the system is functioning.
2. Sound of the pump motor operating, accumulator pressure being released, or the relay operating
may be heard from the engine compartment when the engine is started as the system is being auto-
matically checked.
3. The ABS pump motor may be automatically activated even though the ABS is not operating.
4. The ABS warning light may illuminate under any of the following conditions:
• When the vehicle is traveling on snow or ice with the parking brake activated or a brake dragging
at one wheel.
• When different-sized tires are used.
• When tires of different gripping performance are used.
• When (while the vehicle is jacked up or stuck) only the front wheels are spun for 20 seconds or more.
• When there is insufficient battery voltage.
Note
Under the above conditions, the warning light will not illuminate a second time when the
ignition is switched OFF then back ON, and there will be no memory entry to the control
unit of a problem.
Troubleshooting notes
The ABS is composed of electrical components, mechanical components (hydraulic unit), and the com-
ponents of the standard brake system.
Fundamentally, malfunction of the ABS electrical or mechanical components is judged by the self-
diagnosis function within the ABS control unit. And malfunctions are indicated by the warning light
in the instrument panel.
The location
of
a malfunction is indicated by the technician switching the system to the diagnosis-indication
mode.
The self-diagnosis and indication functions must be used when malfunctions of the ABS are being
diagnosed.
