Hi there. I am Cam. Both of those codes are for the fuel pump control module. The p2534 is for a low voltage and the P069E is a code saying there is an issue or code set in the module. Given this is right after you boosted a vehicle, I would try resetting the codes and see if they return. IF they do, check battery connections and grounds. If you still find nothing then I am thinking you may have caused a surge that damaged your fuel pump module.
I honestly think a reset will work. A code reader is best, ***** ***** may also. Take the battery cables off the battery, hold the ends together for 10 seconds then attach them to the battery and see what happens. This will reset the whole vehicle.If you have 2 batteries, then remove both and touch only one set.
If it runs fine then you likely can go with it as is. IF it was a problem, it would have stopped your engine.
Check wiring connections at the battery for the cables and if that does not fix it then you will need to replace the module. Its not a plug and play, it does require programming once installed.
Sadly I think that is the next step.
