Will Exhaust Brake Activate Trailer Brake Controller

Question

Question:

For the Prodigy P3 brake controller for my 2006 Dodge 2500 Diesel - I have an exhaust brake that I use on downhill sections - will the P3 engage the trailer brakes due to the slowing caused by the exhaust brake or does it have to have a signal from the brake pedal in the truck to engage?

Helpful Expert Reply:

If your exhaust brake lights up the brake lights of your truck then the P3 # 90195 will activate the trailer brakes at the same time.

It's my understanding that when you use an exhaust brake the brake lights don't light up in most situations so it wouldn't activate unless you also depressed the brake pedal enough to light up the brake lights.

Your trailer might be possessed! If the trailer has a battery on it with a breakaway system then that is likely where the power was coming from. Even if there wasn't a breakaway system, if there is a battery on the trailer then it is possible…

The first thing to check is the connectors to make sure there is no corrosion present. That can cause a variety of problems. If that checks out you will need to do some other testing. You can sever the blue wire about 4 to 6 inches from the back of…

What you will need to do is test the brake output circuit of the trailer connector on your tow vehicle with a circuit tester like #PTW2993 to see if there is a constant voltage that is getting applied to this circuit. It should only have voltage when…

It could be that your reverse lockout solenoid needs replacement. Part #T4748800 is the replacement part. But I suspect your master cylinder is the cause for the brakes staying locked up until you release the pressure from the bleed valve on one of…

The Prodigy P3 #90195 will fit your 2015 Ram 5500 and will operate your electric over hydraulic brakes MUCH better than your OEM controller. The OEM controllers rarely work well with the EOH setups but the P3 works really well with them. So to…

I have a suspicion about what might be causing the problem you mention. Do your trucks have 6-way trailer connectors? Or, do the trucks have 7-way connectors, but you are using a 6-way to 7-way adapters because the trailers use 6-way connectors?…
