After PCM Replaced
Hello DN techs, I have had a couple of ford PCM on Ford’s, that after finishing with the programming, sets the CEL with a code P0315, and I have not been able to resolve this issue, I have try to reload the PCM by As build, and not been able to correct it.
Has anyone else have run in to this , and what have you done to fixed.
Thanks in advance. Happy New Year!!
this may be way too simple but I have to ask. Are you doing the profile relearn after pcm replacement?
Richar. I normally start sucking the info from the one in the car, then transferring in to the new PCM. At the end it says calibration check and complete. Something like that. then I performed parameter reset for the PCM in order to start vehicle. There was one weird thing that when I try to do the parameter reset, it would not login to Nastf. back out all the way, then start a new section…
Oscar, Are the replacement PCM's new or second hand. Second hand needs to be addressed with cloning. Newer Fords do not like used parts. Another to consider is the TCM strategy. It would need to be addressed as well.
Yes, this is a New PCM from the dealer. This is the third time that is happening to me, and I have tried many different things to resolve the code, but no success. re-flash by PMI Done it by asbuild, and nothing
Mike Christopherson would help you if you contact him. he commented here on your post.
All you have to do is complete the Misfire Monitor Neutral Profile Correction Procedure using a compatible scan tool :) Check your system test or function test section of scan tool :))
Raul, I’m using the Ford IDS with the VCI-2 OEM. I have never done this after a programming a new module. But I will definitely try to do this, and let you know if works
If you're using IDS software it should be similar to FJDS ( I only use FJDS lol ) it should be under the red tool box tab : under powertrain : Service functions : Misfire Monitor Neutral Correction : )
complete the misfire monitor neutral profile correction procedure using scan tools for code P0315
What does service information say for this fault? Have you checked?
From alldata it says that The PCM has not learned the crankshaft pulse wheel tooth spacing. This DTC disables the misfire monitor.
On newer Fords especially gas trucks will require a crank relearn sometimes after replacing the PCM. I have no idea what scan tool your using but on the IDS its a function under powertrain. This is equivalent to a crank relearn on a GM vehicle. If the only code you have is the P0315 perform the crank variation relearn. The engine will have to be at normal operating temperature before the…
I’m using IDS, and yes I’m very familiar with GM, every time that I do a PCM, the Crankshaft sensor must be replaced, never had to do this on a Ford. Would you tell me where on the IDS you can do the function. I have navigated in all the functions services, and I have not found anything for Crank sensor learning
Not true about gm needing new sensor every time pcm is swapped all you need is to relearn I’ve done the relearn on both Gm and ford after pcm swap and or Internal work done like timing kit
Toolbox-powertrain- service functions- misfire profile correction
Mr. SMith is correct , thank you for explaining it with more details lol Happy New years
You need to do the crank cam relearn Gm vehicles need it after pcm replacement too, never done the relearn through IDS only programming but I do the relearns with my snap on solus ultra or versus edge very easy
First I know it references autologic but it uses the same IDS screens and references the IDS. Follow this link which goes through the procedure step by step. Its the best I can give you right now. Hope this helps. us.autologic.com/news/ford-misf…
Oscar As stated do the MMNPC. Are you performing this function after PCM replacement And programming? It’s a separate function that needs to be performed with a PCM replacement. Can be done with IDS or an aftermarket tool. It’s not part of a PMI or As Built Data programming. Hope that helps you Joe
Thanks to all the fellow techs On this DN for the help that was provided. Was supper simple process to do the misfire profile correction, and after that the CEL clear out. By the way I was able to do it wi the Snapon scanner.
And this is the incredible power of this forum. Imagine the number of techs (like mine) that may now be able now be able to just blow thru this process without a hitch. If we stop for the briefest second and imagine the “clock time” saved across the industry using the knowledge from on this one thread alone. What seems so obvious to some can be a huge time waster for others. I can so see…
