How to read ACURA Diagnostic Trouble Code (DTC) Faults

If the Check Engine Light (CEL) or warning lights such as ABS, Airbag, TPMS are staying ON in your ACURA, a Diagnostic Trouble Code (DTC) gets stored in at least one control unit or module.

In this guide, we will take a look at how you can diagnose and retrieve ACURA fault codes using an OBD-II scanner. Knowing which scanner to use to read ACURA fault codes can be tricky. Level 1 OBD2 scanners can only be used to retrieve fault codes from your ACURA Engine Control Unit. Those are faults that trigger the Check Engine warning light on the dashboard.

To diagnose ABS and Airbag/SRS warning lights you will need a Level 2 OBD-2 scanner. The procedure for reading ACURA fault codes is similar regardless of which scanner you are using.
