What is the reason for the ABS light coming on and then turning off after restarting?

[Lawrence]

This phenomenon is normal and may be caused by poor contact of the wheel speed sensor or momentary abnormal data from other driving system sensors. Many similar warning lights may come on for a while and then turn off by themselves, and this situation does not require much attention. Below is more information about the ABS light coming on: 1. ABS refers to the Anti-lock Braking System, and TC refers to the Traction Control System. These two systems are interrelated. When the ABS detects that some wheels are slipping, it applies braking to the slipping wheels to prevent loss of traction on those wheels. This is the Traction Control System, which improves the vehicle's passability. 2. When the system is working, the yellow TC indicator on the dashboard flashes to alert the driver, and you may also hear the sound of the ABS motor running. There are many types of warning lights, including those that stay on continuously, indicating a persistent fault. Sometimes, the warning light may come on momentarily or stay on for a while before turning off by itself, which are usually intermittent or temporary faults. 3. Most of these are caused by poor component contact or road conditions and do not require concern. For example, if the airbag light comes on for a while and then turns off, it is often due to a loose yellow connector under the seat. The ABS light coming on is also mostly caused by poor contact or damage to the ABS wiring harness. Some warning lights may turn off after disconnecting the battery for about 15 minutes and then reconnecting it.
