Description - CRUISE CONTROL - Fiat ULYSSE 2.2 16V JTD fino a 04/03

The electronically controlled Cruise Control system makes it possible to drive the vehicle at the desired speed without pressing the accelerator pedal.This makes driving on motorways less tiring, especially on long journies, because the speed memorized is maintained automatically.769The device can only be switched on at speeds above 40 km/h or in 4th or 5th gear.The function is managed by the engine control unit. This receives commands from a Cruise Control lever on the left of the steering wheel.The function is engaged by turning the wheel (ON).When a speed is set ( SET + , SET - ), the setting is saved and may be called up at any time ( RCL ).The function is automatically deactivated:by pressing the brake pedal;by pressing the clutch pedal;by turning the wheel to OFF;by switching off the engine;In such cases, the last speed achieved is stored and can be recalled by pressing the RCL button.The system also deactivates at speeds below the minimum permitted speed (about 30 km/h).The Cruise Control lever is incorporated in the steering column switch unit (steering wheel node); the activation, deactivation information, etc. is sent via the CAN to the Body Computer.With the system activated, the milometer warning lights node warning light is lit up.767there is a second "redundant" switch located on the brake pedal, used by the engine management control unit, in particular, for the Cruise Control functionThe "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 - CRUISE CONTROL - Fiat ULYSSE 2.2 16V JTD fino a 04/03

The Cruise Control function is managed by the engine control unit M010.All the Cruise Control function commands are supplied by the steering wheel node control unit M093 to the Body computer node M001. The signal travels via the CAN which connects the two control units.The steering wheel node control unit M093 receives a supply (pin 5 connector A) through the line protected by fuse F11, located in the body computer node M001; it receives a supply via the CAN (pin 6 connector A) from the line protected by fuse F16, located in the body computer node M001.The commands are sent, from the latter, via the CAN, to the ABS control unit M050 and from there to the engine management control unit M010 (pins E3, E4 connector B).The command from the steering wheel node control unit activates the system and communicates the constant speed to be maintained.The system is disengaged as soon as brake pedal I030 or clutch pedal I031 are pressed. If the accelerator pedal is pressed, the system is disengaged temporarily and reset when the pedal is released.The accelerator pedal K055 has two built-in potentiometers (one main one and one safety one) and is connected to pins G3, C2, G2 and H3 of connector A of M010.Clutch pedal switch I031 and the safety switch on the brake pedal for cruise control I035 supply a signal to indicate engagement has taken place to pins E3 and E4 of connector B of M010.The two switches receive a supply from the ignition-controlled line protected by fuse F18 of the body computer M001.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.The warning light is switched on by the milometer warning lights node M140 which communicates with the instrument panel E050 and the body computer node M001 via the CAN.The instrument panel E050 and the milometer warning lights node M140 receive a supply via the CAN (pin 13 of E50 and pin 4 of M140) through the line protected by fuse F24 of the body computer M001.
