D.I.C flashing issue

[jg2000gtp]

Alright so a few weeks ago my D.I.C started blinking 0 for everything while i was driving. a few minutes later it reset and went back to normal and since then it keeps doing it. it will be fine the go to 0 then be fine for a few minutes then do it again. i also noticed that when it goes to 0 the digital heating display flashes. does anyone know what this might be? i dont have a clue

Either you have a junk PCM or a bad ground to your motor.

Yeah had this happen to me... Junk PCM

[SDGTP99]

It happened to me as well. I had a bad engine ground. Check your ground before jumping to buy a new PCM.

[matt5112]

Had a mail-order tune and it did it, swapped back to stock PCM and it was fine.

[jg2000gtp]

the pcm is stock could it just go bad like that?

[matt5112]

yes but check for gounding issues first, stock grounds are pretty ****ty.

[jg2000gtp]

not to sound dumb but where are these located at haha im kinda new to this

[jg2000gtp]

just to clarify imtalking about the grounds not the pcm

[SDGTP99]

There's is a ground on one of the bolts connecting the motor & tranny, idk were the others are. Good way to check for this without having to look is to have the car tested for OHMs, if your car has too much resistance you more than likely have a bad ground.

thanks guys ill check the grounds tomorrow. Since my pcm may be junk and i was planning on getting a new one anyway is there any suggestions toward which one i should get. i was leaning toward overkill

[matt5112]

i'd actually suggest overkill, just try to get in contact first before ordering to make sure you'd get it on a somewhat timely basis.
