sounds like u got it

I’m not sure but the last few posts may have been a bit off topic. I apologize for that.
On the topic of disassembly…. How exactly do I determine how many args a sub is supposed to use, as opposed to how many SAD broke out of the code? I am a bit confused on this part.

Is there an output I could use to run the fusion fan controller?

Also, do you know if there is a function that can be defined to control the fuel pump switch point? I know there isn’t anything in the sct software.

Your DIR, why have you chosen 0068?

Code: Select all

SYM  0068 "SPI_INDEX"                  #UY

RZASA

Code: Select all

0274a: ac,67,52           ldzbw R52,R67          FGTMP5L = SPI_INDEX;

EQE3

Code: Select all

0231d: ac,67,52           ldzbw R52,R67          FGTMP5L = SPI_Index;

Following through various code for TOT and ECT, I agree with what you have done, so it looks like you are on the right path.

Your DIR, what question remains?

Code: Select all

SYM  0328 "PG_DC"                      #UW
#SYM  0328 "F6K_LST_PS"                 #UY# ADDR 889E8_?

SYM  0352 "F6K_LST_PS"                 #UY

You DIR, any reason for PIPCNT to still be in doubt?

Code: Select all

SYM  0355 "PIPCNT_??"                  #UY

You can add this

Code: Select all

SYM  01F8 "N_UNDSP"                     # W #

0186 is N (RPM) so you can change that entry.

Code: Select all

SYM  0186 "N_J1979_01_0C"                 #UY #

Your DIR, any reason for LD_EGO_DLTA to still be in doubt?

Code: Select all

SYM  0438 "LD_EGO_DLTA"                #UW #?

Delete these

Code: Select all

#SYM  06DA "EGR_TCL_CNT?"               # W # Maybe EGR_OFF_TMR? OR DELPR_HOSE?
#SYM  06DC "EPTBAR_HOSE"                # W #

You have pasted in the fault code list without aligning them with the fault code numbers.
Code 113 does not get the name for Code 430, and so on.

Code: Select all

16be8: 13,01              word    113            P0430_CAT2

This is repeated, delete one of them

Code: Select all

RBA    52 00 0230E 02382                    #   # Temp Rbase Sub 0230E

Keep doing what you are doing, except blindly copying and pasting.

It did not even dawn on me that the word was the actual fault code. I pasted those there mainly so I knew it was the location of a fault code when I found it in the code. I will fix this ASAP, Thank You! I was going to fix them as I found them.

Your DIR, any reason for LD_EGO_DLTA to still be in doubt?

No, I guess there is not anymore. I put that when I wasn't positive until I found the other entries in the subroutine. The subroutine starts off a bit different and I wasn't sure at first. Thanks, I will delete the ?

The others I will look into a bit more closely when I get home tonight and report back what I find. Thanks again.

Updated dir file and comparison. I fixed a bunch of things and I think I have the fault code list mostly defined correctly. I have to look up some of the codes still but I feel like I fixed enough to post an update.

eqe3 is reac4, much better off doing eqe4 read0 instead

Thanks for posting the update.
Do Ford have a complete fault code reference for you techs to use?

No, not really. They have a powertrain control and emissions diag reference for each vehicle though. Hopefully they are all in there. Sometimes not all of the codes are in the books for us to reference.

Decipha....Actually I think the bin it pulled from the pcm is FLN0. The PCM has been updated in the past. The tear tag has EQE3 on it though. Before I started learning all of this I couldn't tell exactly what the bin was, now that I have started disassembly of the bin I am pretty sure it is FLN0. I can repost the bin if you are interested in checking it out? I can also post the cmt file that JSA has been helping me with if you are interested?
