Code P068a obd 2 code reader.

[Mylerx]

So I went to work for 3 weeks stored my car inside my garage with heat and when I returned home it was dead. No lights and no life from the engine. Starts with a boost and has check engine light. Used my code reader and pulled the p068a (ecm/pcm power relay de-energized too early, battery voltage, lost communication with abs and lost communication with body control module. I have warranty so it looks like a trip to the dealer.

Should I be concerned? The only
Mods I have is a flow master exhaust but they might use any excuse not to cover me.

Thanks

I should add that once it’s shut off after a boost it won’t start again until it’s boosted.

Although the web pages describing this code sound ominous, the fact that the car sat unused for 3 weeks and started when you jumped it tells me that the first thing you should do is put the battery on a charger and give it a proper charge, reset the code, and then see what happens. You probably just had a dead battery.

If it continues not to start after being put on a charger and charging to 100%, then the battery needs to be replaced.

The second possibility is that you have something which causes the battery to be drained (a parasitic loss). If the battery can take a 100% charge but you check it the next morning and it's flat, try charging it while not connected to the car, check it in the morning. If it stays charged, then suspect the car is draining it. If it's still under the 3 year bumper to bumper warranty the battery should be covered. However if you've added electronic equipment (stereo, accessport, stereo, etc.) which could be the cause of the power drain, they may not.

Thanks. Nothing electronic has been added and I do have full warranty so it should be fine! I’m going to call tomorrow.
Thanks for the help!

Got it back from the dealer, it was a radio fuse blown. 100% back to normal now.

Curious. A fuse inside the radio or the fuse in the fusebox for the radio?

Inside the fuse box.
