2022/Ford/Edge/46,700 mi/Automatic 8 speed/ 2.0 Ecoboost I4
Hi all
I have a 2022 Ford Edge powered by a 2.0 Ecoboost I4 connected to an 8 speed automatic transmission with 46,700 mi. I recently plugged in my scan tool and I got a bunch of trouble codes. The weird thing is that there was no check engine light. My car runs and drives perfectly normal. Here's what the codes are:
PCM: P0316 Misfire Detected On Startup (First 1000 Revolutions)
ABS: B1111 Electric Park Brake Enable, U0265 Lost Communication with Image Processing Sensor A
IPC (instrument panel control module): U023A Lost Communication with Image Processing Module A
BCM (Body Control Module): U023A Lost Communication with Image Processing Module A
HVAC system: U0401 Invalid Data Received from Electronic Control Module/Powertrain Control Module A
Power Steering Control Module: U023A Lost Communication with Image Processing Module A
Any ideas? My mechanic said to erase them but I am hesitant to do so as I thought Scotty and other posts on the forum said that erasing codes doesn't fix the problem.

There's nothing "weird" about that. Communications issues ("U" codes) usually don't, and others may be pending codes that have not risen to the level of triggering the light yet.

Of course clearings codes won't fix an underlying problem. However communications codes are frequently sporadic and may not come back after clearing.

make sure the CEL actually works. When you first turn the key to start, the car performs a lamp check. The CEL light should illuminate for a second or two. Also realize that not all diagnostic faults will keep the light on. If the problem isn't constant, the warning light can turn off again, but the code will still be stored.

Scotty is 100% correct. Clearing codes does not fix underlying issues. However, your issues may have been temporary, and may never return. There's no reason to keep the codes in the computer. You've noted them down, which is good. You can still address them, but there's no reason to keep them there. If the issues still exists , the code/light will come back.
You have a lot of communications issues. These can happen if your voltage drops. Did you recently run down the battery, disconnect it, replace it, or have any electrical work done?
@imperator I recently ran the car for a while in the run position because I needed to plug in my vacuum into the cigarette lighter when I was detailing my car a few weeks ago.
Communication codes can occur from something as simple as a weak battery. With no CEL and no performance hit of any kind, clear the codes and run the car through several drive cycles, and then scan again. You know the initial codes so when you scan again you'll have a better idea of what you can eliminate. Scotty has often used this same approach.
Check your battery/cable connections before delving to far into other areas. Loose connections will cause this.
