★ Top Answer
The error code A7EA for the GMC Acadia may not actually be an error code, but rather a code indicating that more information is needed for the OBD scanner. This could suggest that the diagnostic tool being used is not compatible with this GM vehicle. If the menu code A7EA and 7E8 appear, it could signal a problem with the catalytic converter. The best course of action would be to bring your vehicle to a dealership or an auto service mechanic for them to run an OBD diagnostic scanner to determine if there is another issue. Alternatively, you could visit an auto parts store where many locations offer scanner rentals or borrowing options for you to verify the codes independently.
