Question and answer for ABS
1. What is ABS?
ABS is abbreviation for Anti-lock Brake System. ABS ensures good brake
stability and steering on various roads to get best brake distance.
2. Why need ABS?
When braking, front wheel will lock up to lose steering ability; while rear
wheel will lock up to run to a side or slide. ABS will help you to control
vehicle and to steer clear of barrier during braking.
3. How to distinguish if your vehicle equipped with ABS?
Firstly, you could observe if the ABS warning light on instrument cluster or
on switchboard is on in short period. Secondly, you may ask your dealer.
4. How does ABS work?
The ECU in ABS will adjust the pressure on each wheel brake through solenoid
according to VSS signal. It just likes a good driver but with much faster
reflection.
5. How to distinguish ABS is working?
When ABS is working, you will feel the vibration of brake pedal, and hear the
noise of hydraulic controller is working. Keep step down on the pedal. At the
most situations, the brake distance for vehicle with ABS is shorter than the
vehicle without ABS, especially on icy road or wet road. Please remember to
turn steering wheel to steer clear of barrier.
6. What should do if ABS is fault?
Once ABS is fault, ABS warning light will be on. ABS will not work, but the
conventional brake system is working. So you could brake vehicle as usual way.
7. When will ABS light be on?
ABS light will be on for about 1.7s after engine starting, then turns off.
Only ABS is fault, ABS light will be on again. So once ABS light is on, go
to service station at once. Don’t try to repair ABS by yourself.
