i just bought a 1996 powerstroke, previoulsy had a 2000 7.3 and a duramax so im pretty familiar with them but today i was playing with auto enginuity and it passed the CCT but when i did the buzz test and KOEO test it came back with 2 codes. they diddnt trip the ses light though. the codes are 1219-CID stuck low, and 1298 IDM failure. i dont think i have a bad idm because the truck runs fine but im not sure about the 1219 code. is that an internal idm problem or maybe a bare wire shorting out? what is CID? thanks

 

This website will definately help you, the codes are about halfway down its a pretty long page

Im not sure how to make it a hypertext link. this is the 1219 code off that site

1219 PCM/IDM CID stuck low Cyl. identification line stuck low (historical fault only) CID circuit short to ground, probably intermittent

 

ha hypertexted itself

 

1298 PCED IDM failure Internal IDM failure Internal IDM failure
Probably not good. if its still running thats a weird code tho . i didnt think they would run at all with bad idm but i may be wrong

 

thats what i thought. its a weird code. i would think an idm failure would cause all kinds of problems? im wondering if there is a wire rubbed through somewhere on the cid circuit shorting it out and because that code is thrown the computer thinks the idm is bad also. just wondering if anyone had this problem and if it was an internal idm problem or an external(wiring) issue

 

are you having any problems at all?

 

I had the 1298 and bought a new IDM and sure enough I still get the 1298. I dont worry about it and keep the old IDM under the seat just in case.

 

the 1219 is a chaffed or broken wire, its pin number 96 on your pcm. a yellow with lihgt blue tracer. runs from the pcm to the idm, if that wire is good then the idm is bad.

the 1298 is probably related to the first code.

 

I'm impressed Joe, do you have a photografic memory?

 

Joe you are amazing. The things you know are astonishing. Glad you are on this site.

 

thanks ill have to get out the multi meter. thats kind of what i was thinkng that it said the idm was bad because one circuit in it was bad but wouldnt a cylinder i.d cirucit shorted to ground cause problems? the truck seems to run fine

 

certains things i do remeber photographicly, but with each passing day there are less and less....lol. the tank parts are taking over. i do recall most of the basic circuits but i always double check my pced's before posting when it comes to wire colors and numbers

 

what is the cid
