I scanned my jeep cherokee and in the control module the codes $7E8: Engine and $7E9: A/T pop up. what does that mean? my abs and traction control lights just randomly came on.


Unfortunately the code reader you used is spitting out garbage.

Proper codes will start with a letter followed by four numbers. P0102 for example.

Dtc u1000 and u1096 on gm 3500 8.1 truck


Check the battery cables, make sure the clean and tight, also check the left body ground.
Those two codes are just for communications. They do not usally mean there is a fault in the system. It means that one modual was unable to talk to another modual for a split second.
Which modual had the codes stored in it?
