Location of componentsComponents DescriptionThe brake lights are located at the rear in the side lights and in the central third brake light and consist of 10 separate bulbs.All three bulbs are operated whenever the brake pedal is pressed, by means of a switch on the pedal itself.The circuit is supplied with the ignition switched ON and is protected by a fuse, in the junction unit.A braking signal is also sent from the switch to the ABS, which detects braking status and therefore introduces braking control.The same signal is also sent to the JTD engine management system, which takes the braking condition into account when determining the engine control mode.On versions equipped with radios, a switch is fitted on the brake pedal with a special filter to prevent interference when the pedal is pressed.
Functional description The switch I30 is supplied when the ignition is switched on (INT) from the line protected by the fuse F1 for the junction unit B1. When the brake pedal is pressed, the switch closes and sends the supply to the side brake lights in the rear light clusters F30 and F31 and to the centre rear light F40.
