Question

2014 Jeep liberty with OBD2 code 7e8

Answer 1

Code 7E8 is not an OBDII code. When the OBDII scanner plugs in your vehicle, the OBDII scanner gets the 7E8 ($7EA and $7E8) code from the ECM. The code is 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.
