Acura ABS Light ON Troubleshooting GUIDE

Last Updated on Monday Mar 05, 2018

If the ABS light stays on in your ACURA it means that the Anti-lock Braking System (ABS) is NOT working. A fault code is stored in the ABS module and retrieving the code will help you find out why the light is on. If the ACURA ABS light stays on it may take longer to bring the car to a complete stop especially on slippery roads. Diagnosing ACURA ABS can be performed by the dealer, auto mechanic. You can also read Acura ABS codes yourself, using a Level 2 OBD-II Scanner. In this guide, you are going to learn how to read Diagnostic Trouble Codes (DTC) from the ABS module of your ACURA. Plus common problems that trigger the ABS light.
