I have the following codes on my peterbilt 387 with a C15 ACERT engine. (1)- 128 030 5 SID (2)- 128 031 5 SID (3)- 128 032 5 SID (4)- 128 129 1 PID (5)- 136 231 9 SID (6)- 000 002950 5 SPN (7)- 000 002951 5 SPN (8)- 000 002952 5 SPN (9)- 000 000385 1 SPN If anybody knows any of these please help me out..

Check this place out www.topix.com/forum/com/cat , look up a guy called "Ken Mech" he is a cat mechanic that helps a lot of people out.
Thanks a lot! That's a very helpful place! Haven't had time today but I'm gonna look him up tomorrow...
I have the OEM service manual with me in the truck at all times if you don't get a answer from anyone let me know and I could message you my number and I could look them up for ya. That would be just too much info for me to try to type from my phone.
to the best of my knowledge since im not sure how u got those type of codes here is what i show in my book. 6 iva 1 current low 7 iva 2 current low 8 iva 3 current low and thats all i can help you with i dont see any of the other ones in the book. what year is the truck and what is the engine serial number???
1),2), and 3) are injector codes, 4) is injector metering rail code, 5) is ABS code (I think), 6),7) and 8 are iva codes, can't find anything on 9) but they all are under the valve cover (except 5) sounds like a engine wiring harness to me, its pretty much plug and play, if its got more than 7-800,000 miles on it it probably needs a harness they are notorious for going bad.
The truck year is a 2005 and the serial # is MXS09066. I asked my local dealer and he said these codes were not any codes that he could describe or explain. I got them from a computer scanner I bought for trucks.
Well my injectors seem to be working fine, the truck engine runs smooth and strong. I am however having engine brake issues. Sometimes it works good but sometimes it super weak if not working at all. I have heard about the wiring going bad and I also think that could be at least part of my issues. S I'm going to change it when I get back home and see what changes. I will let you guys know if it solved my problems. Thanks a lot for the help and info!
When you seen multiple low current codes (FMI 5), you most likely have a harness issue. The injector harness's have an very high failure rate, which is most likely 1 of your problems with the IVA codes. However, you have more going on there, the other codes do not rely on either of the injector harness's. That's more likely a main harness. You really need to get it hooked up to Cat ET and do some diagnosing.
