OBD2

OBD (On-board Diagnostics) 2 is a car industry standard for diagnosing issues in cars.

For the Chrysler Crossfire, it is located near the hood opening handle, under a hinged lid that you can pop off.

For common errors, you can use an OBD-2 reader, such as the ELM327, but some components of the Crossfire require the Mercedes STAR Diagnostics to read and reset errors.
