Description - BRAKE LIGHTS - Fiat ULYSSE 2.0 16v fino a 04/03


The vehicle brake lights are located at the rear in the side light clusters and in the special central third brake light, consisting of 10 separate bulbs.They are operated each time the brake pedal is pressed via the special switch on the actual pedal.767there is a second "redundant" switch on the brake pedal used especially by the engine management control unit and the ABS control unit. [EL5030], [EL7023].The "basic" switch (I030) is the "normally open" type (when the pedal is pressed, the switch closes), whilst the "redundant" switch (I035) is the "normally closed" type (when the pedal is pressed, the switch contact opens): the system checks the consistency of the "pedal pressed" information in this way.

Operational Description - BRAKE LIGHTS - Fiat ULYSSE 2.0 16v fino a 04/03


The brake lights command comes from the brake pedal switch I030, connected to the body computer node M001 at pin 2 of connector B and is supplied directly by the ignition switch H001.When the pedal is pressed, supplies are sent to the left rear light cluster F030, from pin 1 of connector H of the body computer node M001, via the line for fuse F05 and to the right rear light cluster F031 and the third brake light F040, from pin 10 of connector H of M001, via the line for fuse F17.
