1 Answers
When the warning light displays abc, it indicates a malfunction in the automatic stability and traction control system. The illumination of the ABS warning light can be related to several factors: malfunction of the wheel speed sensor; ECU malfunction. Below are the specific reasons: Wheel speed sensor malfunction: When the ABS light comes on during normal driving, it is because the ABS computer detects a system malfunction. It might be due to a wheel speed sensor of a certain tire not functioning properly. The ABS computer cannot recognize the driving conditions of each wheel and cannot compare the slippage of each wheel, resulting in the ABS not working correctly. ECU malfunction: ECU circuit board malfunction; ABS control unit ECU programming issue.
