The most common problem with the sensor (trailer) pedal is the brake pedal problem. Often when setting the alarm, the sensor is simply forgotten to plug in. After it is connected, the system is restored to its replacement.
Also, the light bulb can light up due to problems in the autostart, and more specifically, in the diode on the clutch of the clutch, which closes the circuit of the brake pedal. The diode needs to be replaced.
