Plug trailer on my truck and trailer had a short took the fuse replaced.now my speedometer dont work ,and my abs and park light stay on also no more 4 by4. model of truck is dodge diesel 2007

Yes. Thus is a short. Check the switch wiring and bulbs. Does the car have a trailer hitch with trailer wiring. Those are a common source of shorts.

If only the speedometer is inop, it will 90% of the time be a speed sensor. 1 10mm bolt and a plug tales 5 minutes to replace
If any other issues occur it is likely In th dash and see earlier suggestions or seek a professional shop, or a salvage yard to replace the cluster . Is your easliest solutions

Perhaps this can give you some ideas and steer you in the right direction. Do a Google search:

I came up with schematic diagrams which may help you trace out the circuits. I hope this helps.

ABS light is on because brake light circuit is down. Did you replace the park lamp fuse? Check trailer light connector if you have one.

Got much the same trouble... Well similar anyways. Started with burned wires in the harness above drivers side fuse box. Headlights stayed on even with switch off and key out. Then melting of the break light fuse ( bypassed that with an inline fuse to the break light switch). Then my park lights done much the same thing, now I turn the truck off and the heater fan stays on but wont turn back on after I move the switch to off. Also it will turn off if I turn on the parklights. Ugh

Well, that sucks, for sure. The only commonality I can see between the engine, abs, brake light and speedometer is possibly a bad vehicle speed sensor. But when you throw in the codes for lost comm and cluster error, that muddied the water a bit. I am sure that there are separate fuses for the trailer wiring harness (my 04 chevy has separate fuses, surely an 09 dodge does) so I doubt trailer wiring could have done all this. A lost comm could be caused by a blown fuse. I would inspect every single fuse I could find in the entire vehicle, also, I have researched your problem a bit and have found a couple possible fixes. One is that the abs sensor on the rear differential is known to be sketchy and needs to be changed. The other is cleaning any ground cables that are connected to the fuse box on the front left fender. I hope this helps!

Not sure which fuse you checked.
The Engine Compartment Fuse Panel ( Battery Junction Box / BJB ) is where the fuse is for the trailer tow adapter parking lamps.
Fuse # 5 is the fuse for the parking lamps, and the reversing lamps.

Next is the trailer tow adapter park lamp relay. This is what BJB Fuse #5 feeds, and the coil is operated by the truck's parking lamps. This is also in the BJB, Relay 201, it is the 1/2 size relay.

Not sure what you took a resistance reading from on the trailer tow adapter.

If you want, you can pull the trailer tow park lamp relay, and jumper the normally open contacts, which should provide power at the trailer tow adapters, regardless of the truck's lights.


This is the wiring diagram for the trailer tow park lamps

Check the ABS sensor on each wheel. Also check all fuses first.

You need to take it to a qualified repair technician like this guy ! Because neither of you have a clue an never will . Lights on check for code's .

You must have a bare wire at the back of your truck that's shorting out where gravel stones have pounded the outside coating off. If you have an after market trailer plug on there, you might want to check that out too. The connections to your main wires from the trailer plug, are never done properly, and always cause problems somewhere.
