abs and brake light on

Hello,

The ABS light gets triggered when the on-board diagnostics detect any fault within the ABS system.
It can be due to a bad sensor, wiring or bad module.
Best course of action would be to scan the vehicle and retrieve the ABS trouble codes.
The codes can help with the diagnostics.

Generally, the codes can tell you what area the issue might be.

Please let me know if you have any questions.
Thank you.
