How To Fix The Service Trailer Brake System Alert
If you own a truck, you may have experienced the service trailer brake system alert while driving, even without a trailer attached. This can be frustrating, but don’t worry, there are some easy fixes. In this blog post, we will discuss why your truck might be saying service trailer brake system with no trailer, and how to resolve it.
Our focus is on fixing the service trailer brake system alert, so let’s get started.
Check Brake Fluid Reservoir Level
The first step to rectify service trailer brake system alert with no trailer is to check the brake fluid reservoir level. If the brake fluid is low, it may cause the brake system to malfunction and generate an alert. Here are tips on how to check the brake fluid reservoir level:
- Open the hood of the truck and locate the brake fluid reservoir, which is a clear plastic container located near the engine.
- Check the level of the brake fluid by looking at the marked lines on the outside of the container. If the fluid level is below the minimum mark, then the fluid needs to be topped up.
Top Up Brake Fluid And Reset Service Trailer Brake System Alert
Once you have checked and confirmed that the brake fluid level is low, it’s essential to top up the brake fluid to its correct level. Here is how to do it:
- Purchase the recommended brake fluid online or from a local auto store.
- Open the brake fluid reservoir cap and fill the container with the recommended brake fluid until the fluid level is between the minimum and maximum marks.
- Once done, put the cap back on and start your truck to confirm that the alert has disappeared.
Replace/Repair Brake Sensors/Leads
If the brake fluid level is adequate, but the alert still appears, then you may have a faulty or damaged brake sensor or lead. These components play a crucial role in monitoring the brake system’s pressure, and if they aren’t functioning correctly, they can cause an alert to appear.
Here are some tips on how to detect faulty or damaged brake sensors/leads and how to replace or repair them:
- If a sensor or lead is faulty, the brake system’s pressure may be low, causing the service trailer brake system alert to appear on the dashboard.
- Take your truck to a reputable auto repair shop and have a professional examine the brake sensors and leads to determine which one is faulty or damaged.
- If a sensor is faulty, it may need to be replaced with a new one. If a lead is damaged, it may need to be repaired or replaced.
- Once the faulty sensor or lead has been replaced or repaired, the alert should disappear.
Replace Abs Module
If none of the above solutions resolves the service trailer brake system alert with no trailer attached, then it may be time to replace the abs module. The abs (anti-lock braking system) module is a critical component in the brake system that regulates the pressure in the brakes when the wheels are about to lock up.
Here are some signs of a faulty abs module and tips on how to replace it:
- If the abs module is faulty, you may hear a grinding sound when you apply the brakes, or the brakes may not function at all.
- Ensure that the vehicle is switched off, and the battery is disconnected from the truck.
- Locate the abs module, which is usually mounted on or near the brake master cylinder.
- Remove the mounting bolts and electrical connectors from the abs module.
- Replace the old abs module with a new one and reattach the mounting bolts and electrical connectors.
- Reconnect the battery and turn on the truck to check if the alert has disappeared.
The service trailer brake system alert can be a cause for concern when driving your truck without a trailer. However, you can easily fix the problem by checking the brake fluid reservoir level, repairing or replacing faulty brake sensors/leads or replacing the abs module.
If you are unsure or uncomfortable performing these fixes, it’s always advisable to take your truck to a qualified mechanic for professional assistance.
