Basic OBD2 scanners can only be used to retrieve fault codes from the Engine Control Unit (ECU). Those are faults that trigger the Check Engine warning light on the dashboard.

To diagnose ABS and Airbag/SRS warning lights, a multi-system OBD-II scanner is needed. Here are some popular scanners you can use:

  • Launch Creader VII+
  • Autel ABS SRS Transmission Scanner
  • Foxwell Full System Scanner

The procedure for reading Cadillac fault codes is similar, regardless of which scanner you use.

When the Check Engine Light (CEL) or any other warning light such as ABS, Airbag, or TPMS turns on, or you get a warning message on Driver Information Center (DIC), a Diagnostic Trouble Code (DTC) gets stored in the corresponding control module.
