Service Trailer Brake System – Meaning & Error Reset

Service Trailer Brake System (STBS) is an electronic control system that applies the trailer brakes in proportion to the tow vehicle brakes. STBS is required on vehicles towing trailers over 3000 kg with a total combined weight of 4500 kg or less, and can be factory installed or retrofitted. When STBS is fitted, the trailer must have its own brakes that are capable of being operated by the STBS.

STBS uses sensors to monitor the tow vehicle’s brake pedal position, brake light switch status, and road speed. When the tow vehicle’s brakes are applied, STBS calculates how much braking force is required from the trailer based on its weight and adjusts the trailer’s brakes accordingly. This ensures that both the tow vehicle and trailer stop in a coordinated manner, which helps to prevent jack-knifing.

If there is a problem with STBS, an error message will be displayed on the control panel. The most common cause of an error message is a faulty connection between the control unit and one or more of the sensors. To reset the system, follow the instructions in your owner’s manual.
