When I bought the 2001 Dodge Ram 1500 two wheel drive a few months ago, a previous owner had tried to upgrade from the original no-frills ohc to the computerized one. They apparently thought there were two plugs so it would simply plug in. I finally had time to pull the dash to fix the blown heater core, and made a harness for the ohc. I already had the high end body contoller. However, When I first turn the key, I am greeted with "OC" as a compass heading, and 248 degrees as a temp. When I push the Step button to cycle, I get around 300 as a DTE, which is about right because my tank is full, but he next displays show only "CCD". It even displays that when I get back to DTE, and shows no compass heading or temp after cycling through. Any ideas? P.S. I know it plugs in two places, and have wired accordingly. I would love to get it going before I get frustrated and put it back together as-is. Thanks!!

 

bumpity bump-bump bumpity bump-bump... I hate being pushy but I need this truck back the day after tomorrow....

 

I think the computer has to be flashed for the overhead console. If i'm not mistaken!!!

 

Grab the 2001 service manual from the FAQ section here, that should give you at least a starting point.

 

This should help:

Got it, and poured over it. No clues. I read that maybe CCD doesnt mean "Check Crystal Display", like I thought it did, but "Chrysler Crash Detection". Where do I go from here?

 

BUMP BUMP BUMP If it helps, for the two seconds it works, before saying "CCD", it says 248 degrees outside.... my other truck with a working display says -40 degrees with a disconnected temp sensor, so i guess that sensor lead is shorted out?

 

Good bet... and probably also why is goes into failure mode almost immediately. Find the short, or, simply unplug the sensor, and see if it 'works'.

 

I put a compass/temp sensor from a 1998 in my 2001 over the weekend.
The temp gauge works great but the compass only shows east/southeat/south.
I only paid $15 for the wiring harness, overhead console and rear view mirror so I didn't get stung to badly.
I guess I will go find another overhead console or maybe just the display portion.

 

Anyone know where I can buy a computerized one. My truck is already built for it but I had a few subs that shot it to hell. It goes out on me then I have to hit it for it to start working properly then it will come back on. Plus the clips in there where broke near the rearview. I cant find em at any junkyard around where I live.
