What is the reason for the ABS warning light to return to normal after restarting?

[DelJosiah]

ABS warning light returning to normal after restarting may be due to the following reasons: 1. Front wheel slippage: When driving on icy or snowy roads, if the front and rear wheels rotate differently while braking simultaneously, the ABS light may illuminate; 2. Sensor interference: If the ABS wheel speed sensor's sensing area on the wheel is covered by contaminants such as mud or dirt, it can affect the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and calculating the wheel slip rate, thereby failing to issue appropriate commands to adjust braking; 3. Brake system malfunction: If both the ABS and parking brake lights illuminate simultaneously, it indicates a potential serious issue with the vehicle's braking system. In such cases, you should not continue driving. Immediately reduce speed, pull over to the roadside, and contact a repair shop for assistance.
