Some Integrated Brake Controllers May Not Function Properly - A Helpful Troubleshooting Guide From Our Friends at Load Trail
We are an authorized Load Trail dealer and we found this news bulletin regarding factory installed brake controllers to be very helpful. Many newer model tow vehicles come with integrated brake controllers. This helpful guide explains how to troubleshoot a fairly common problem that involves the tow vehicle not recognizing a trailer when it is connected.
Recent research found that the new integrated brake controllers on various makes use the resistance of the bake magnets to see if the trailer is connected to/disconnected from the towing vehicle. When a trailer is connected to the towing vehicle, all of the lights may work but the towing vehicle may still recognize the trailer as disconnected. This is caused by the truck “viewing” but not recognizing the resistance of the brake magnet.
Some towing vehicle makes include;
Chevy | GMC | Dodge
To resolves this issue, follow the steps below;
For Chevy & GMC;
Start the towing vehicle and then connect the trailer plug to the towing vehicle.
Drive 7 miles, pull over and turn off the towing vehicle and removing the key. Leave the trailer connected to the towing vehicle.
Wait 1 minute, restart the towing vehicle. This should "force" the truck to recognize the trailer.
Dodge;
Dodge has an integrated brake module flash to resolve the issues for year models 2015 & 2016. Visit your local Dodge dealer to have the dealer perform the TSB 08-82-16 ITBM to resolve this issue.
