2013 3500 Issues?

[13HD3500]

Hey guys,

Having a couple of problems with my 2013 3500 ST DRW....

1). High Beams - Flash to pass works (pull stick back) but I've got nothing when I push the stick forward...I'm guessing it's the multi-function stick but just wondering if there's anything else I should check first?

2). Trailer wiring...Every-time it's wet out I get the check trailer brake wiring message multiple times (3-4 times a minute) popping up on the dash with no trailer in tow..probably a dirty plug? Also has the plug in box for 5th wheel hookup if that matters.

3). I'm getting Battery Saver Mode a lot as well, it's pretty cold here. Both batteries are in blankets and dash is showing 14 volts running down the road. Was going to clean up the terminals and spray them, anything else I should be doing?

4). Engine Brake - It works at highway speeds and slows the truck down to around 70 km/hr then cuts out and the truck rides neutral until I stop...is this normal? Never had a pickup with one before so unsure. And what's the difference between Full & Auto?


Thanks!

For the trailer wiring, check where the wiring plugs into the back of the 7 pin plug, see if something is loose. The plug for the fiver it t-tap plugged into back of the plug on the bumper, you could unplug the fiver harness to see if your problem goes away.

As for the battery save issue, pull the negative cable off of one battery and check the voltage of both batteries after the truck has been off overnight/several hours. If your close to 12V one of the batteries, it probably getting week. You might want to get them load tested. If they're o we 4-5 years old it may be time for a new set. I have read that some people have had issues with the Intelligent Battery Sensor that is on the negative terminal.

1. If the high beam bulbs are working when you pull back on the arm, that tells us that your wiring and bulbs are good. I would suspect the switch itself.

2. Trailer wiring short - I would check the ground first. Sometimes the trailer wiring relies on just the ball as its ground to your truck. If you have access to another trailer, see if you get the same warnings with it.

3. The battery saver mode is being triggered by the cold weather. Mine came on a few days ago and gave me a message in my EVIC. It went away the next time I started the truck.

4. The Exhaust Brake will take a little time to get use to. There are two modes, Normal and Auto. Neither will work if the engine RPM's are below 1100. In the Normal setting, tap your brakes while going down a hill. The EB should not let your truck go above the last speed you were running. The steeper the hill, the more EB will be applied. The Auto mode EB will kick in without hitting the brakes whenever you let off the fuel.

Now, here is the bad... The EB works off of the Turbo and is controlled by a Turbo Actuator. If your truck is a 2013 and the actuator is the original, plan on replacing it before long. Don't go to the dealership, you can do it yourself with a Cummins Rebuilt one for less than $400.

Thanks for the info! I forgot to add I'm getting the trailer message with nothing in tow lol.
