Normally, your trailer’s brake lights will illuminate green when you first apply pressure and stop the engine. If, for some reason, there is a problem with the brakes, however, the “blue” message on the dashboard will illuminate instead. Learning how to reset service trailer brake lights so they light up blue can save you money on repairs, prevent further damage to your vehicle and give you peace of mind knowing that the trailer brakes are properly working.
Reset Service Trailer Message
The “blue” message that indicates brake difficulty is not always reliable. Sometimes, this is simply a mistake by the manufacturer.
Other times, it indicates a more serious problem with your vehicle that needs to be tended to by trained professionals. For example, a battery that has failed, the starter that isn’t running, or other problems with the electrical system could all cause the “blue” message to illuminate.
In the past, these were the only kinds of messages that you would see on your service trailer dashboard.
Today, you can find a wide variety of alternate “blue” warning signs including lights that flash in the wind, warning lights for low oil pressure in the hydraulic system, or loud whirring noise. While you’re looking at your service trailer, you might as well be checking out how to reset service trailer brake lights, since these too are pretty basic.
The warning lights and “starting” sounds are designed to make you aware that the wheels are off the brake system, and to get you moving quickly away from the vehicle so it can be serviced safely and effectively.
How To Reset Service Trailer Brake Lights
When you look at how to reset service trailer brake lights, you should think about what the actual problem is so you can have your wheels back on the brake system soonest possible. Solving the problem will turn the warning light off. Below are some common issues related to the blue message.
Lack of Brake Fluid
One common problem with brakes is a lack of brake fluid. This is a simple enough problem to solve by yourself if you have access to some old brake fluid.
It’s best not to try this method if you don’t have access to any old fluid, though. Instead, have your brake fluid changed immediately, and contact a service trailer repair company if you aren’t sure how to go about it.
If you’ve already had problems with your brake, there are a few other things you can try when you learn how to reset service trailer brake lights. If your brakes are still making noise, but not nearly as much as they did when they were first installed, it could be that you haven’t properly maintained them over the years.
Either way, you might find that your brakes are wearing too thin. In this case, you might want to consider having both the brake pads and rotors checked and replaced. You might also want to have your brake light cables checked and replaced as well.
Check the Rotors & Brake Pads
When you learn how to reset service trailer brake lights, you should keep your eyes open for problems that may be causing them. If you see any signs of wear or any deterioration on the rotors or pads of your brakes, you should replace them as soon as possible.
Brake Light Cables
Also, if you see any damage at all on your brake light cables, you should replace them as well. This is especially important if you ever have to tow your vehicle because damaged brake light cables will make the brake system less effective. Plus, they will increase the risk of your tow becoming unsuccessful.
When you’re learning how to reset service trailer brake lights, it’s important to remember that you should do this carefully. You don’t want to cause more damage to your vehicle or wreck itself! If you need to, use your emergency start feature in order to easily get yourself out of the situation.
Note: Sometimes the message doesn’t go off even though you have checked everything. In this case, it is probably the manufacturer’s mistake. You can contact your dealer and talk to them.
Learning how to reset service trailer brake lights is something that can easily be done by anyone with basic knowledge of vehicle repair. The most important thing is to be safe, and if you feel that you are at risk, you should make sure to take action. If you don’t, you may end up costing yourself a lot of money in repairs or even in accidents. In the long run, it’s better to be safe than sorry!
