Sync screen, dead battery, no radio or backup camera problem

FloridaBill · 2025-10-06T16:43:08-0400

So I was driving my 2015 Transit 150 xlt and wanted to listen to the radio. I press the radio power button and it starts playing. But only one channel shows. No matter what channel I choose from the memory, the one that it's stuck on plays. Then I press CD. Nothing happens. Same thing with media. Nothing happens.

I pull over and kill the van to see if I'm doing something wrong. When I fire it back up, the sync display is blank. No matter which buttons I push, the screen is blue blank. (See image below).

I go home and check the fuse for the sync in the passenger fuse box. It's good. Then I check the fuse for the radio in the body control module. It's good.

The radio still doesn't work.

I leave it overnight and when I come back the next morning, the van battery is dead, and the sync window is warm to the touch. Apparently the now blank sync display didn't shut down when I closed and locked the van and it ran the battery down.

I can live without the radio, but I can't have the audio system draining the battery overnight. The van is completely stock. No aftermarket additions. The radio is the mid radio with CD player.

Any suggestions on how to fix or how to unpower the radio and sync? Pulling the radio fuse didn't turn off the sync display.

Thanks for the wiring diagram. Best I could figure out was to pull fuse f16 in the body control module. But it made no difference. Sync display still on after key is off, fob locked, an hour later. I hate to have to take it to the dealer . . .

looks to me like fuse F19 would be worth pulling to test.

I tried pulling F19 like you suggested, and it worked. It kills the power to the mid display, including the back up monitor. That solves the power drain problem. The hardest part was getting my big hand through the small opening and around the thick cables to get to the Body Control Module fuse block. I had to use a pair of small forceps to get the fuse out. I tested by starting the engine, trying out the temp, fan, & ac, and they still work. Thanks for the suggestion.
