"Check wire connection" 2015 HD

Just towed for the first time with my new Duramax that arrived 3 weeks ago. About 10 minutes into the drive my truck displayed " check wire connection" and beeped for about 3 seconds. This would happen every 10-15 seconds and at other times every 15 minutes. After beeping it would show "trailer connected". My brother in law had the wire harness plug swapped out on our 2014 27 ft Attitude toyhaler last week since he towed it a few miles while dragging the harness. My thought is that they failed to connect the new plug in correctly. My brother in law is going to hitch up the trailer to his 2011 duramax this weekend and drive it around for about 30 minutes to see if it triggers it on his truck. Has anyone experienced the " check wire connection" on their 2015 Duramax? If it does trigger it on his truck then the trailer supply place screwed up. Any other way to check it?

Hooking up another trailer is the fastest and easiest way. From your description, it sounds like one of two things: either a wire is loose in the plug or at the connection point in the trailer, or a broken wire some where in the cord. Other than that, you'd need to check out the harness on your trailer with an ohm meter.

Did you check the plug connection to make sure it was plugged in far enough for the latch on the lid to engage the plug?

Yes. I pulled over and pulled the plug out and re-inserted it back in the receiver making sure it went all the way in and that the little tab on the latch was holding the plug in place. The alert kept going off during the 3 1/2 drive and the return drive as well. Pretty freakin annoying. Weird thing is it didn't go off until at least 10 minutes into my drive.

Here is some information for you:

Driver Information Indicators and Messages
The following indicators are used to inform the driver of several different factors.

TRAILER CONNECTED
This message will be briefly displayed when a trailer with electric brakes is first
connected to the vehicle. This message will automatically turn off in about ten seconds.
The driver can also acknowledge this message before it automatically turns off.


CHECK TRAILER WIRING and TRAILER NOT CONNECTED
This message will be displayed if:
  • The system detects a trailer with electric brakes is connected to the vehicle, and
    then the trailer harness becomes disconnected from the vehicle. If a trailer connection
    is made initially and the vehicle or trailer wiring connections is not correct the
    TRAILER NOT CONNECTED message will be displayed during the ignition key up as if there
    is no trailer connected.
  • The trailer connection is recognized initially and then a disconnect occurs while
    the vehicle is stationary, this message will automatically turn off in about thirty
    seconds. This message will also turn off if the driver acknowledges this message off
    or if the trailer harness is reconnected.
  • A disconnect of the trailer wiring harness occurs while the vehicle is moving, the
    CHECK TRAILER WIRING message will continue until the ignition is turned off. This
    message will also turn off if the driver acknowledges this message off or if the trailer
    harness is re-connected or repairs are completed.
  • There is an electrical fault in the wiring to the electric trailer brakes. The CHECK
    TRAILER WIRING message will continue as long as there is an electrical fault in the
    trailer wiring. This message will also turn off if the driver acknowledges this message
    off.
  • A poor connection at the 7–way connector may cause the CHECK TRAILER WIRING message.
    Some aftermarket 7-way trailer side connector adapters or plugs may cause deformation
    or excessive wear to the vehicles trailer terminals. It is recommended that you use
    an OEM or Pollak Heavy Duty 7-Way Trailer Side Connector Adapter.

And some more info:

Check Trailer Wiring Message on the DIC
  1. This condition is caused by insufficient grounding between the trailer and vehicle.
    • To correct this condition, perform the following procedure:
    • Inspect and clean the ground wire (white wire) connection on the trailer side of the 7-pin connector.
    • Make sure that the wires inside the trailer side connector are clean and securely fastened.
    • If an electrical junction box exists on the trailer, make sure the wires inside the junction box are clean and securely fastened.
    • Once this procedure is complete, check to see if the condition has been corrected:
    • Remove the original trailer ground wire (white wire) from the trailer side of the 7-pin trailer connector.
    • Install a ring terminal (PN 12103512 or equivalent) to this wire and fasten the ring terminal to the metal or aluminum chassis of the trailer using a M6x1x20 self taping phosphate zinc coated screw (PN 11515925 or equivalent).
    • Pre-drill trailer chassis location with a 3/16" hole. Make sure the trailer chassis location is clean of paint or coating material prior to installation. Galvanic corrosion between dissimilar trailer and screw metals may require that this ground location be periodically cleaned.
    • Obtain a sufficient length of minimum 10 gauge (5.0 mm2) white wire and fasten with ring (PN 12103512 or equivalent) terminal to the trailer chassis at the same location as the original ground wire.
    • Install and fasten the other end of the new ground wire into the trailer side of the 7-pin trailer connector.
    • Install conduit on the original and new trailer ground wires, and secure the conduit to the existing trailer harness.

Using a multimeter, measure the resistance between the bottom two pins on the trailer connector. Should be around 2ohm. Your are measuring the brake magnet resistance.

Thanks for all the info guys. Since the trailer supply shop is only 1 mile from my home we simply took the trailer back to them yesterday morning. We tightened the ground wire and re-checked the 7 connections and all looked good. I towed it back to storage, also about 1 mile away, and right as we were pulling in the chime went off again and showed "check trailer wiring". We took it back to the trailer repair and he said just to leave it there and he would change out the plug later in the day. After that I took my truck to the shop to get lifted. He called us and said he changed the plug and towed it with his 2006 Silverado with intergrated trailer brake with no issues. Since my truck is currently in the shop getting lifted we picked it up this morning with my brother-in law's truck which is a 2011 Duramax also with intergrated trailer brake and had no issues either. Not sure if the intergrated trailer brake on the 2015's is more sensitive than the 2011's or not but once I get my truck back which most likely will be tomorrow night I will hitch it up and tow it for a few miles to see if it trigger the chime. If it does then it must be something with the receiver on my truck.

The "check wire" issue is happening on our new 2015 Sierra Denali. Several times while towing our Airstream trailer, the "check wire" light came out.

We took the truck to the dealer and they could find nothing wrong with the wiring.

magictony, you last posted on this thread in October. Can you give us an update on what is happening with your truck? Are you still getting the "check wire" message? Is anybody else having any problems with this?

We're just trying to figure out our next step. Appreciate any help with this issue/problem.

Thank you.

I ran into this problem last fall with my TT. Previous truck (2012 Sierra 1500 Denali) had no issues at all. New 3500 arrived in September and on the first time towing I got the same "check wire connection" message. We pulled over and I had my wife monitor the dash as I wiggled the wiring at the 7-way and the message would go on and off as I messed with it.

Once we arrived at the campground I spread the pins on the trailer wiring and it didn't make a difference as I received the same message periodically on the way back home. That was the last trip we took before winterizing and I plan on inspecting all of the wiring on the truck and trailer when I prep for the season next weekend. If nothing works correctly after that I plan on replacing the factory 7-way and seeing if that makes the difference.

Some quick google-fu led me to this forum and to some other forums talking about the same problem. I'm wondering if there is an issue with the 2015 7-ways. (?) The other forums talk about ground-wire inspection. I hope that's the issue as it will be the quickest solution.

Unfortunately I keep having the same issue. I went through two new trailer plugs ( the recommended GM plugs) as well as replacing the receiver portion ( truck end) at the dealer. While at the dealer they cleaned all the wires including the ground and said they found nothing wrong. I took my hauler back to the manufacturer since they are about 25 minutes away. They replaced the complete wire harness and also said they found nothing wrong with the harness. Pretty freakin frustrating. I read on another thread that it might be a loose wire on the trailer brakes itself so I will try that next. Any help would be appreciated.
