What do codes $7E8 and $7EA mean on a 2005 Cadillac STS?

Question

These codes ($7E8 and $7EA) came from an Autel CAN OBD 2 code reader and the car is a 6 cylinder 2005 Cadillac STS.

Answer 1

The codes 7EA and 7E8 are not OBDII codes. When the OBDII scanner plugs in your vehicle, the OBDII scanner gets the 7EA and 7E8 ($7EA and $7E8) codes from the ECM. The codes are a menu of systems that the OBDII scanner can access. OBDII scanner interprets the codes and displays the menu. Some scanners can't solve these codes and show the codes instead of the interpretation. Clicking on the code menu will read the OBDII codes (e.g. P0420 or P0455), if any, from that system.

Menu Code 7E8 ($7E8): Engine System

Menu Code 7E9 ($7E9): Transmission System

Menu Code 7EA ($7EA): Engine Management
