Troubleshooting A Non-Working Autowbrake Trailer Brake Controller

Question

Question:

Purchased Autwbrake and installed. Followed instructions and connected wires as instructed. The Autowbrake shows its getting 12V to system and well as to the fuse. As the small cap on the fuse was not attached when arrived, so it made it easy to diagnose voltage at that point. I get no LED lights on Autobrake when pressing both buttons on top of system. I do get a LED light on the system when brakes are released, but no effect on the electric brakes. I tried to and diagnosed issue for a couple of weeks. All lights work on trailer and there is 12V going to brake wire. I finely took it off and installed a traditional brake controller and it worked perfect. I just cant get this to calibrate or respond to the pressing of the two buttons on the Autowbrake. The vehicle is a 2013 Chevy Silverado LTZ with tow package. It took me 30 minutes to install dash controller.

Helpful Expert Reply:

Since you confirmed the Autowbrake Electric Brake Controller # 3430001 had 12v power running to it the only only other thing to really check would be that the rest of the 5 wires were spliced into the proper circuits. With proper power and ground even if it wasn't activating the brakes you should be able to adjust the gain settings and get the corresponding amount of flashing lights. I've run into issues before where I ran a separate ground to the trailer frame and that solved the issue so I would start with that first.

If you still can't get it to even light up when changing settings then I would reach out to the manufacturer for a warranty replacement as there is likely a defect with the unit and wasn't really anything wrong on your part.

The Autowbrake brake controller part #3430001 that you referenced draws up to 15 amps. It's only going to draw amperage when the controller is activating the trailer brake so it would not be something you'd need to install an on/off switch on…

The Autowbrake #3430001 is a great choice! To add a 7 way to your 2017 Dodge Grand Caravan you'll want to use the #ETBC7L, since it doesn't require the wiring of a brake wire into the vehicle like the #ETBC7. You will still need to run a wire…

You are correct you will need the 4-pole flat part #118727 and the part #etbc7 to get a 7-way on the back of the Jeep to power the Autowbrake part #3430001. The blue wire from the ETBC7 to the front of the vehicle is not needed because the Autowbrake…

Hi John, If you have a factory brake controller you would see something like I have pictured below. The + and - will adjust gain and the other buttons slide together for a manual override. With you only having a 4-pole connector I doubt they…

As long as the 7-way was installed correctly with a circuit breaker protected connection to the tow vehicle battery, the #3430001 Autowbrake Brake Controller you mentioned will work just fine. A single axle trailer will only draw about 6 amps at full…

Answer 10

Since the Autowbrake Electric Brake Controller #3430001 ties into the turn signals it's most likely thinking the signal for the turn signal is actually the stop signal and is activating the brakes. Since there really isn't any troubleshooting…

You are going to need our 7-Way RV Upgrade Kit #ETBC7L to tow a camper having a 7-way behind your 2017 Subaru Outback with a 4-way flat connector. The Adapter #HM47365 you found does go the opposite way from what you need. The charge line included…
