Question about 2003 GMC Sierra 1500

1 Answer

I have a 07 chevrolet silverado 1500 that came with tow package. I took it to the dealer and had a brake controller installed. The pin on the connector for the brakes shows four volts all the time, even with the truck off. it does not change when the brakes are pressed. I am worried that it will keep the brakes on my travel trailer engaged all the time. Is the constant voltage normal? this was the second controller that I got. I wired the first one and had the same problem, so I took it to the dealer.

Call the dealer and tell them your concerns so that they may troubleshoot and correct the problem. They should have checked it themselves to insure they did a proper job.

Truck won't shut off until I unplug my tent trailer? Just pick up new trailer and had a 7 pin connector added to my truck along with a brake controller

It sounds like someone messed up to me! Apparently, the brake controller got wired into an ignition circuit that it should not have gotten wired to. When accessories are added to a vehicle, it is extremely important that the vehicle wiring diagrams are used so that you know EXACTLY what you are tying into. Some of the Chevy trucks that are sold with trailer towing packages already have the wiring for brake controllers under the dash. This makes installation easy and is already tied into the correct things.

My 1999 Silverado has a dealer towing package installed but not the brake control. The truck wiring recepticle has the blue wire running into the wiring harness going to the front of the truck. Any idea...

Hello af4lb.

Usually you will find this wire taped up to a harness just behind the underhood fuse panel.
Follow the large harness up from where it goes to the rear under body and it should break out of the harness there. You may have to slide some tape back to see it.
I hope your search goes well.
Thank you for using FixYa and have a happy New Year.

It sounds like you lost a ground.
check traier hookup first.
Probably not the controller.
P.S. There are multiple fuses for this setup. check all ! ! !

Constant voltage on brake controller pin at connector.

you should not have voltage unless you apply the brakes on the vehicle or the brake controller. the only constant voltage you should have is the charge line on the 7-way.

Brake contoller showing 4 volts on the connector pin all the time

If the controller uses a SCR to switch the power on to the trailer brakes there can be some low voltage leakage across it. If you measure the amperage I would guess it's milliamps.

Service trailer brake system message

I got this error too on my 2007 2500HD and I wasn't too thrilled for the fact that I had to tow a 7k trailer w/o it's breaks for four hours.

I did get an answer though.

If you look it up in the manual, the "Service Trailer Break System" indicates an error in the truck intigrated break controller.

I just took my truck in to the dealer with this probelm and they said it is a "Known Engineering problem".
Quick summary of what the service manager said:
First they are replacing a cylinder, if it fails again they will reaplace a board.

Towing package

Did you get any directions w/ brake controller? On Some vehicles you can't connect wires of the same color from vehicle to controller, they use a different color code for the wires, so it may be a wire connected improperly, even though all the colors match. countrycurt0
