please help, i am at ready to quit- code 44

[Shelby_Daytona]

hello,
i posted previously about a code 44 that i am getting. Has anyone else ever gotten a coder 44? I know it is the FJ2 wire, and have already been to MiniMopar, but i dont know which wire it is and i have to clue whatsoever how to find it. I bought a little cucuit tester and the light woudl come on for some wires, but not for others. Does ANYONE at all have any clue how to help me. It wont idle and therfor you have to hit the gas to get it to start and it runs rpetty bad. I also changed the SMEC jsut to see if that would fix it, but it didnt. Same thing. Does anyone have a wiring Diagram? I think i should jsut buy a new SRT....i loved working on cars, but after the 4 years of trouble this thing has given me i am ready to shoot myself (not really, but close enbough)
thanks alot

Check pin 4 on the power module (14 pin connector on the SMEC) with the key in the RUN position.

You should have +12V. Check pin 3 on the same connector. Should be the same +12V.

If you do, check pin 12 on the 60-pin connector on the SMEC for +12V. If you don't have it, check the K14 splice. It will be two dark blue 18 gauge wires splicing over by the diagnostic connector (by the relays). They'll be going to pin 12 and 3 as discussed above.

Also check the dark blue wire on the ASD relay for +12V. If it has it, the splice is your problem. Fix the splice, or just make a new splice between pin 12 (big connector) and 3 (small connector).

If you don't have +12V on pin 4 of the smaller connector, check the J2 splice. You should have it, though, since the car starts. The ASD relay won't work without it. The J2 splice is a little harder to find. It's inside the wire loom right where the wires to the relays split from the main harness.

THANK YOU for replying....i was gettin pretty curious as to why the resource himself hadnt helped yet..hahah by the way, it is much appreciateed. I went to the dodge dealership here adn the guys in the shop let me look at a shop manual, electircal wiring diagrams, but it took me probably like..2 hours to find what i was looking for. Once i found that, i got it photocopied and it has a list of all the connectors and where they go. I checked #4, as it is the J2, and it had 12V or so with the ignition on, and none with the ignition off, which is right. This was all i knew what to check for, so i checked just to make sure that there was current from the 17-20 pin connectors (AIS WIRES) to the AIS, and there was...so i was stumped. I tried using booster cables to make more grounds, but it didnt help. Also, when the car is runnning ( i havent driven it, jsut tried to start it, and had to use the gas a bit) the fan comes on right away. It NEVER did that before, only came on when the temp got up to a certian point. I have no clue why it is doing that. **** car. I will go check the other pins in which you told me to, and let you know. thanks alot again...

okay mr. overland, and all others reading, i tested #4, the J2 wire. It was good, at 12+ V. I tested #3 (both of these on the 14 pin connector) and there was nothing. I tested # 12 on the 60 pin. Nothing. I found the splice, with the wire from the 60 pin connector not connected. it was all green adn corroded. I took the splice apart, and there was one wire that goes to the 14 pin connector, and the other which went to the little box on the finder (not the fan relay or the starter relay, but the other relay box on the actual fender). Into it goes one blue/whie wire (the one that goes to the splice), a larger RED wire, which always has power, a large Green adn black wire, and a smaller blue and yellow wire. I reconnected the splice up, cleaned the wires off good, made a good connection, so one blue and white wire comes out of the relay, and then splits up and one goes to the 14 pin connector one goes to the 60 pin connector. All seems well. Still NO voltage at the #3 or #12. ????? Ignition was on, but still nothing. what else coudl it be? i fixed the broken wire.....i am lost again. Could it be that relay or something?

Well, that relay box thing you found was the ASD relay.

Does that tester you you're using have a continuity test? (ohm or diode test will do). If so, unplug the power module connector (14 pin one) (having the battery disconnected would probably be a good thing too). Measure for continuity between the 3rd and 4th pin on the power module connector (the one in the SMEC, not the one with the wires). There should be continuity (dead short). If they're open, the power module is bad. Since you said you changed the SMEC with same result, there might be a short (pin #4 to ground) causing the pm to fry.

The fan coming on is probably the computer being in limp-on mode. Check codes again. Anything other than 44?

Oh, and the reason I hadn't helped yet.. First time I saw your post I was at work with no wiring diagrams. Now I'm at home with the FSM's in hand!

hey there,
sorry to put you through all of the extra trouble, i jsut disconnected the battery again, plugged everything in (14 and 60 pin connectors) to the SMEC and put the battery back on , and it fired right up fine. Thanks sooo much....you have no idea how much i appreciate it. If you ever need anything i can help you with, let me know. I put the stock SMEC in jsut to see what the difference would be, as when i turned 16, i got the MP SMEC, and my license, and never drove it with the stocker. What a difference i tihnk. That extra 2 psi makes a difference. You also saved my ass from missing the street legal drags tomorrow. thanks soo much again. 3 cheers to PER OVERLAND..haha

Awesome!

Glad it worked out!!!
