Question

2011 Chevrolet Aveo 4 Cyl showing 7E8 on obd check engine lite test

Answer 1

The code 7E8 is not an OBDII code. When the OBDII scanner plugs in your vehicle, the OBDII scanner gets the 7E8 ($7E8) code from the ECM. The code is a menu of systems that the OBDII scanner can access. OBDII scanner interprets the code 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

Answer 2

This is not a code but the menu what it means is Engine management data and any stored codes,
