The ABS warning light appears while driving, indicating that the ABS anti-lock braking system is faulty. There may be a problem with a certain sensor or circuit and the signal cannot be transmitted. The ABS module could not receive the speed signal from a certain wheel. At this time, the car can drive normally, but the ABS system cannot be activated, which can easily cause the rear wheels to quickly lock when braking, causing skidding.
During the annual vehicle inspection, the ABS light will come on after measuring the exhaust gases. Since only the front wheels rotate during the test and the rear wheels stay stationary for a long time, the speed difference between the front and rear wheels cannot be very large in normal driving, so the system will think that the ABS is faulty and the light will come on. If it is this group, just turn offthe flame and wait more than ten seconds to relight it, and the ABS warning light will go out by itself. Some cars don't come out, you can drive them for a while then leave after a few minutes.
When the vehicle has just started and the ignition is on. This situation is normal, because each time you turn it on, the vehicle will have a self-checking program, not only the ABS light, but also many indicator lights on the dashboard. Once the test is completed, there is no problem and the ABS light turns off automatically.
