great find! hope all is well now.

 

Glad you got it!

 

Junk wires are gone

 

Thanks again every one.

 

I'm glad you cleaned that up. There is the possibility that they may have contributed to the CTM failure.

 

Since this thread isn't that old, I figured I'd just post here instead of starting a new one.

When I bought my 2002 Dakota 2 months ago, the passenger-side high-beam didn't work, but I figured it was just a bulb. I finally got off my lazy *** and replaced the bulb... and that didn't fix it. The driver-side high-beam and both low-beams work, so I was thinking the multifunction and headlight switches were probably fine.

I downloaded the repair and parts manuals off this thread, but I can't find a 2002 Repair Manual. It gets a little confusing because if you look at the Parts Manuals, the '01 and '02 CTMs have a different part #, but the '02 and '03 CTMs are the same. But if you look at the '03 Repair Manual, it doesn't even have a CTM. It uses a completely different system centered around a completely different module (the Front Control Module).

My eyes-on observation of my '02 tells me I should be using the wiring diagrams in the '01 Repair Manual. Doing so, I found my CTM isn't outputting any voltage to the right-side high-beam (connector 3, pin 2).

Does this mean my CTM is bad? I can't find a fuse or relay that could be responsible. If the wiring was bad, I'd still get 12V out of that pin on the CTM, wouldn't I? Anything else I should be checking?

Should I have posted this in a new thread? This is my first post here, so I'm not sure how folks like things done.

 

There is only one input for the high/low beam select so if it works on one side and not the other, the CTM is likely toast.

The feed from the CTM goes to the bulbs, through the bulbs, to ground.

The 2003 manual you see, it's not a Dakota. It's for a full size Ram 1500. You can tell by the body code at the top of the page, DR.

 

Yeah, I was afraid of that. Maybe I'm just used to working on older cars, but it seems like overkill to replace an entire computer just for one busted high-beam. It is what it is, I guess.

I was toying with the idea of jury-rigging a relay off the working high-beam to power the dead one, but then I saw the pictures in this thread and decided against it.

Wow, I wish I had noticed that earlier. Would've saved me an awful lot of confusion. LOL.


Thanks!

 

I had this same problem on my 2001 Dodge Durango. I bought a 12 volt general purpose relay. Powered the coil side of the relay off the passenger headlight when the headlights were on. Ran a fused circuit thru the relay contacts from a battery circuit. Did this so I wouldnt over load the passenger side head light circuit. Been that way for about 10 years. Has worked out fine. Just another option to replacing the CTM. Thank You
