2018 Focus ST - Pioneer AVH 2440 - Battery Drain

Post by Tx.matt » Thu Jul 11, 2019 8:12 pm

I installed the Pioneer AVH 2440 along with the Maestro RR a few months back and I have been having an issue with battery drain in my 2018 Focus ST. I have been through the wiring multiple times and can't seem to figure it out. I have also gone as far as replacing the battery in the car but the brand new battery was drained within a few days as it is not a daily driver. When it is all powered up everything works as it should. Everything that I flashed on for the steering wheel controls works great and even the factory reverse cam works great. Is there a new firmware flash for this issue? I probably flashed the RR some time in February. I saw in another post that a wire needed to be clipped in one of the harnesses. Any help would be greatly appreciated!

What was the OEM Screen size- 4.3 or 8"? I didn't think the STs came with the 4.3.

I see your flash is for a 4.3" screen back in December, before we supported the 8". If you flashed for the wrong trim, I recommend updating your RR and flashing for the correct trim, and that should fix it.

On the 8" radios, the car needs specific codes sent to it so it can go to sleep properly; the old 4.3" firmware doesn't have these messages. This is why we insist that people wait until officially cover their trims, to save stuff like this from happening.

It is definitely an ST base model that came with a 4.3 inch screen.

We have updated the firmware a few times since your original flash; I definitely recommend updating your RR.
