Hi I’m looking for any help with our 2008 GeorgeTown Forest River 340. I need a Ford f53 ecu 7c3a-12A650-DSC it threw several codes about control module P0607, throttle actuator P2107, transmission P0707 & P0706. The check engine light came one and it killed 3 times in 1 mile. Mechanic hooked his scanner and got the same codes. The throttle body was changed, it ran for 5 min, killed and won’t start, then ecu stopped communicating…then the ECU was sent off for repair in FL but the computer board inside the ECU is unrepairable. No support from Ford or the RV dealer. I’m looking for a serviceable ECU or any advice where I can get it rebuilt..Broken down in Louisiana Thanks

This company is in NY and they want $150 to diagnose it but we already know the computer board inside is bad. Any one else in this form had this issue or know where I can get one that works>

There are many references to capacitors on the ECU going bad and causing problems. They can be repaired if one has the skills, perhaps this might work in your case.

Finally received my original ECU (PCM) back not repaired. No one has one in stock or repaired so I put it in and the Triton V-10 fired up and ran smoothly for 8 min until the engine clusters went blank and check engine light came on (lost everything but the rpm) I unplugged the battery & cleared the codes. After 4 hrs of cooing off she started and ran for 4 mins, killed and wouldn’t restart with a funny long starter sound. I got some new codes B1317-20 (battery voltage to high) new 13.0 volt battery Fluke tested on the AGM battery and 14.2 with engine is running new alternator ) B1352-60 Ignition in circuit fault U2023-20 fault from external node & U0100-20 CM
Lost communication with the (PCM). Anyone else experience any of these issues ? All fuses are good and I put a new relay on the PCM slot. Frustrated we’ve been stuck at the RV park for 3 weeks and can’t find anyone to trouble shoot the wiring. Any suggestions Flagship one vs Car electronic exchange out of NC for PCM repair ????

Not likely wiring if it starts, warms a bit and fails. The traces on the ecm boards are probably corroded out and that is why no one can repair it. If it's a lower or upper board trace there's guys that bypass the problem with wires. If it's a sandwiched board there's no getting to it. Ford needs to be ran out of business.
