• What Does Reese Brake Conroller ER Code Mean
  An ER code on a brake controller indicates an internal problem and would mean it's time to replace it. For a replacement the Brake EVN # TK63VR is a very reliable and better performing controller than the Reese you have now.

• Troubleshooting Hopkins Impulse Trailer Brake Controller Error Message OE
  The troubleshooting guide for the Hopkins Impulse trailer brake controller does not list an error code "OE" but if the unit displays a flashing code "SC" this indicates a short on the brake output circuit or a defective brake magnet, which is unlikely on a new Aliner. Those error codes can sometimes be difficult to read. My Hopkins contact said much older versions has error codes E1, E2, E3 but not OE. I suggest taking a close look at your Tacoma's trailer connector. Corrosion issues on...

• Troubleshooting Pilot Electronic Brake Controller Not Activating Trailer Brakes
  When the trailer is connected to your vehicle and the brake pedal or manual lever is not activated, the Pilot Electronic Brake Controller # 80550 should display a ".C" to indicate that the controller is reading the trailer. If your controller only ever shows the dot, the brake controller is not recognizing that the trailer is connected. The first thing I recommend checking is the trailer connector at the back of the vehicle and on the trailer. You will want to make sure that the connector...

• Should a Reese Pilot Brake Controller Show a Decimal Point When Trailer Brakes are Applied
  Actually the decimal point of the Reese brake controller part # 80550 that you have should only come on when the manual slide or vehicle brakes are applied without a trailer connected. It sounds like yours is working properly. Have you tried connecting a trailer to the tow vehicle to see what happens? If it doesn't show a connection most likely the problem is corrosion on the trailer connector of the vehicle or trailer. I attached a help article on troubleshooting brake controllers for...

• What Brake Controller is Better, Tekonsha Prodigy P2 or Pro Series Pilot for 2019 GMC Terrain?
  Hello Patrick, Between the 2 brake controllers that you mentioned I would go with the the Tekonsha Prodigy P2 # 90885. The main reason is because the Pro Series Pilot # 80550 is time delayed, so there will be a delay from the time that you hit your brakes in your GMC for the brakes to be applied on the trailer. Honestly, I am surprised that they still make the time delayed brake controllers. The Tekonsha P2 # 90885 is a proportional brake control, meaning that it works at the same time...

• No Power on Blue Brake Output Wire on Reese Brake Controller
  Assuming that the compact unit and the old unit use the same connection point, then you may be correct in saying that your compact unit is toast. Before pitching your compact unit, you may want to do some testing first. The first thing that I would check is the connection between the blue wire from the brake controller and the brake output wire going to your 7-way connector. If you use a plug in style connector, then make sure there is not any corrosion, damaged wires or bent pins. If...

• Display of Pilot Brake Controller # 80550 Is Blank When Trailer is Not Connected
  The Pilot brake controller will not show anything on the display unless a trailer is connected or the manual brake switch or vehicle brake pedal is pressed. If you apply the brake or the manual brake switch, and see the decimal point on the display, then the controller is correctly installed and all is well. I've linked you to a copy of the owners manual for the Pilot brake controller, as well as to a copy of our brake controller troubleshooting article that you might find helpful in the...

• Horse Trailer Brakes Activate Without Vehicle Brake Pedal
  The '.C' means that there is a trailer connected and isn't an indicator of a problem. Are you by chance using an adapter in the 7-way connector to change it to a 6-way? If you are, there are two common ways to wire that connector. One uses the center pin as the brake output, the other use the center pin as the constant 12-volt power supply to the trailer. If the vehicle is wired one way and the horse trailer the other, it would certainly explain why the brakes immediately apply when the...

• Installation of Electric Brake Controller on 2012 Isuzu NPR Connect
  For your Pilot 2-6 Brake Electronic Brake Controller - Time Delayed # 80550, you will need to connect the black power wire to the battery of your vehicle using a circuit breaker like # PK54530 and # 12-1-1 wire. Then you will connect the red wire on your controller to the cold side of your brake light switch. From my research it looks like that is the green with white tracer, but you can check it with your circuit tester # PTW2993. The correct wire will show no power when the brake pedal...

• Troubleshooting a Reese Electric Trailer Brake Controller OL Error Message
  An OL error code would indicate an overload error. The cause of this is most likely a bad ground or a short to the blue brake out put wire. The first thing I would check is the connector on the back of your vehicle. Any dirt or corrosion can be causing a bad ground or a short to the brake out put pin. The solution is to clean out the connector and get rid of any dirt or corrosion. It would also be a good idea to clean out the trailer side connector as well. There could also be a bad ground...

• What does ".C" Mean on Trailer Brake Controller Display
  The ".c" display on your Pro Series Pilot Brake Controller # 80550 is simply an indication that the unit has power and is connected to a trailer load. If you are hooked up to your trailer, this is exactly what you want to see on the controller screen and means that everything is working properly. I recommend applying the manual slide on the controller to see if the display changes to a number, indicating power being sent back to the trailer brakes. You can also take your trailer to...

• Low Power Output on Reese Pilot Brake Controller
  I took a look in the owner's manual for the Pilot 2-6 Brake Electronic Brake Controller part # 80550 which is included for you and in the troubleshooting chart it shows that if power output is less than "1.0" on the digital display the error could be attributed to one or more of the following: 1. Power set too low. 2. Poor connection on brake line (blue wire). 3. Black and white wires reversed, control destroyed. Since you have stated that you turned the gain up on the brake controller...

• Video and Info to Help Troubleshoot Brake Controller
  We have videos that cover how to test and troubleshoot a brake controller. I attached the link to this video on this page. Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide. Using a circuit tester like the Quickee Tester, part # PTW2993, you should get output to the controller side of the wire you severed. If the manual slide activates the trailer brake output wire...

• Troubleshooting Aggressive Braking and Only Red Light on Pro Series Pilot Trailer Brake Controller
  Hi Matt; is this the Pro Series Pilot Trailer Brake Controller # 80550? Assuming it is, the red dot alone indicates that a trailer is not connected. You should also have a "c" on there with the trailer connected. That also probably means there is some kind of internal issue with the brake controller if the brakes are working even though it thinks a trailer isn't connected. I would double check the connections on the brake controller, test the brake output circuit on the 7-way, make sure...

  Hey Mike thanks for stopping in! It could be a number of things, honestly, so the best thing you could do is check everything.

• Recommended Brake Controller for Motorcycle Trailer with Brakes
  For your trailer, you can add brakes since there is the flange already mounted to your axle. You will need to pull one of the hubs off your trailer spindle to see if you can get the bearing numbers off the face of the inner and outer bearing of that hub. If the numbers are not legible, then you will need to use a digital caliper like # to measure the spindle where the bearings rest on the spindle. I have attached a photo to assist.

• Why Would Pilot Brake Controller Only Show Red Dot When Trying to Apply Brakes
  On the Pilot brake controller # 80550 the red dot appears when you step on the brake pedal or use the manual override WITHOUT a trailer connected. If a trailer is connected and you only get the red dot then the controller is not reading that a trailer is connected. This could be from a dirty or corroded trailer/vehicle side connector, a wiring problem to the brake magnets on the trailer, or a break in the wire from the controller to the vehicle trailer connector.
