Help with Check Engine light

[Little Guy]

I have a 2019 Mustang GT A10 with a Roush Supercharger Phase 2 (Phase 1 with 1-2 upgrade). I have had the SC almost 2 years. I just had the battery changed and noticed 1 1/2 weeks later that the engine light was on. I checked the code and it was P0607 which is the ECM. I thought it could be the ECM was receiving low voltage thus causing the error. Dealer check it and that wasn’t the cause (Dealer also installed the SC). The car has now been at the dealer for about a week. Has anyone ever experienced this or know what it can possibly be. The car still is running ok.

Has anyone performed the battery management reset

With that code the reset would be my first step

I‘m not sure but I will definitely ask them. I hope they did because the battery s the first I mentioned to them, at two different dealerships.

Thanks

Lots of times a lubtech will change the battery and not really know what they are doing

Update: I still don’t have my car back. The problem was not the battery management system. They also tried to re-flash the roush tune. The engine light went off but came back on. Now, they will be changing the PCM. This is the holiday season so approvals for these repairs under warranty have been slow. I have a loaner vehicle but it is not a mustang.

I'd ask for the bronco as a loaner for your inconveinece... Dealerships here have them on the lots.
