7EA error code - Cars & Trucks

Chevy Mechanic:
Hi my name is ***** ***** I'll be more than happy to assist you. Please allow me a few minutes to review your information. Thank you
They are what they call "generic" codes. Some OBD11 or OBD2, "same thing", generic reades will give a $7E8 and $7EA. together and maybe a $7E9.
These are for a submenu. Click on each one separately and you should or might get a regular "P0" code if your scanner
has the supported module. If not either get a better scanner

Those are typically ECU addresses...... 7EA and 7EB are response addresses HVECU and the Traction Battery

// ECUs
// -- request/response
// -- 7E0/7E8 for ECM (engine control module);
// -- 7E1/7E9 for TCM (transmission control module).
// -- 7E2/7EA for HVECU (Hybrid contol module)
// -- 7E3/7EB for Traction Battery
// -- 7E4/7EC
// -- 7E5/7ED
// -- 7E6/7EE
// -- 7E7/7EF

7EA is not a trouble code. Some OBD scanners display this code when it needs more info, such as which component group to check. Your best bet mite be to take your vehicle to a qualified repair shop.

Those codes mean the reader you are using is the wrong one. Make sure it is CAN OBD 2

Those are not valid fault codes. the would look like this PXXXX "X" being a number.

Honestly, no idea acout Saturn Aura's error codes.
But, looks to me that those two mechanics you called are not really very efficient,
Guess you should look for a GOOD mechanical service and get your car's computer scanned by someone who really knows how to use a scanner,

That is what they call a "generic" code. Some OBD11 or OBD2, "same thing", scanners will give a $7E8 and $7EA. together and maybe a $7E9.
These are for a sub menu. Click on each one separately and you should or might get a regular "P0" code if your scanner
has the supported module. If not either get a better scanner or
go to a "big box" auto parts store and they will scan it for free and
should be able to give you more information.
Please comment or feedback if helpful.

no such codes, if a three number code it will start with po then the number. if a four digit code it will start with a p. good-day! GM codes,

7E8, 7EA. Cat failure.
- Check the health of catalytic converter.
- Check for cracks in muffler.
- Check air leaks.
