1 Chapter 1 MULTIPLEXING I- BRIEF DEFINITION Multiplexing is different from previous electrical technology in that it involves transmitting several items of digital information between various devices on a single transmission channel, in the form of 2 wires. II - PURPOSE OF MULTIPLEXING Multiplexing is used to: • simplify electrical harnesses, • increase functions (for the same number of wires).
2 Chapter 1 III - DESIGN OF THE XSARA PICASSO AND XSARA MULTIPLEXED NETWORK XSARA PICASSO design BSI 8080 8410 8415 * 0004 XSARA design BSI 0004 8500 8600 * 8410 8415 Key: The dotted lines represent a connection used only by the diagnostic function.
3 Chapter 1 IV - THE VAN PROTOCOL The network consists of 2 wires, called: • Data, • Data B (Data bar). The Data B wire is so called because the voltage at its terminals is always opposite to the voltage on Data. Data 5V 0V t 5V Data B 0V t Two current levels are used to encode two distinct logical states. This process is used to: • limit the radiation given off, • provide good resistance to interference.
4 Chapter 1 Format of the communications message (frame): Only the rate of the Data line is represented as the Data B line is the opposite. A message in a multiplexed device is unambiguous. It is therefore not possible for an error to occur regarding the recipient nor the nature of the command to be performed. A frame consists of 9 fields: a start of message identifier used to locate the start of the message.

23 Chapter 2 VII - OPERATING MODES A - NOMINAL MODE OR CUSTOMER MODE All functions are operational. This is the operating mode designed for normal vehicle use. B - STAND-BY MODE In this mode, there is no communications activity and ECU consumption is minimal. The BSI scans its wake-up inputs. Each multiplexed device is able to wake up the network. In each case, it re-supplies all the ECUs by a positive called the +VAN.
24 Chapter 2 VIII - AFTER-SALES OPERATIONS, ACCESSORIES A - GENERAL In the factory, an initialisation procedure is performed at the end of vehicle assembly in order to allow the various devices to recognise each other: • ignition key with integrated transponder and BSI, • HP remote controls and BSI, • engine management ECU and BSI, • radio and BSI. B - ACCESSORIES All new devices which have not undergone a programming procedure are not recognised by the system and are therefore not operational.
25 Chapter 2 D - REPLACEMENT OPERATIONS 1 - Customer confidential card The access code (4 characters) is given to the customer on a confidential card. It can be seen after removing the masking strip on the card. It is required for all maintenance procedures on the system. CITROËN IMPORTANT: Before adding or replacing parts, ensure that the customer is still in possession of his confidential card. 2 - Loss of access code The access code is linked to a chassis number and managed by the CITROËN network.

76 Chapter 3 C - OPERATING MODES 1 - Operating phases • When the ignition is switched on. The control panel compares the last fuel level displayed with the level indicated by the fuel sender (variable resistor fitted with a float). In the event of a significant difference, the gross level information is displayed otherwise the last fuel level displayed is given. • When driving. The fuel sender is no longer used. The engine management ECU supplies the fuel flow information to the BSI.
77 Chapter 3 III - SPEEDOMETER FUNCTION A - GENERAL The instantaneous speed of the vehicle is displayed on the digital displays of the instrumentation screen. The driver can access the choice of measurement units (KM/H or MILES). The units are changed using the menu of the multifunction screen (refer to the Clock/Date/Temperature function). The units selected by the driver are stored and recalled the next time the ignition is switched on.
78 Chapter 3 C - OPERATING MODE 1 - Operating phase Nominal operation: see layout The speed sensor (located on the gearbox) supplies the BSI with a variable frequency signal. The BSI calculates the instantaneous speed of the vehicle and encodes it in a VAN frame. The control panel takes this information from the VAN network and displays it.
79 Chapter 3 IV - MILEOMETER FUNCTION A - GENERAL Role: mileometer The mileometer consists of two digital displays: • the main mileometer, • the tripometer. B - LAYOUT Refer to the speedometer layout. C - OPERATING MODE The BSI calculates the total distance travelled since the vehicle was first used from a signal supplied by the speed sensor. It then encodes the value in a VAN frame and sends it to the control panel. The main mileometer displays the total distance travelled.
80 V- Chapter 3 MAINTENANCE INDICATOR FUNCTION A - GENERAL 1 - Role The aim of the maintenance indicator is to improve the service to the customer by automatically showing when the next servicing operation is due. Interval between maintenance operations.
81 Chapter 3 2 - Display h V19 Zone "h": maintenance indicator. Every time the engine is started, the distance remaining is displayed on the mileometer. LED V19 either illuminates or not.
82 Chapter 3 C - OPERATING MODES 1 - Nominal mode The BSI calculates the total distance travelled from the signal supplied by the speed sensor. It then encodes the value in a VAN frame and sends it to the control panel. The control panel calculates the distance remaining to be travelled before the next service using the following parameters: • the maintenance frequency stored in the control panel (this is decremented as miles are driven), • the time elapsed (incrementation of the number of days).
83 Chapter 3 3 - Initialising the maintenance indicator The initialisation procedure is used to assign a new mileage value and a new time value to the system. The procedure is as follows: 1 - Press the Tripometer reset button. 2 - Switch on the ignition. The display shows a key (LED V19) and a 10 second counter starts to count down. 3 - Keep the Reset button pressed during these 10 seconds. The key disappears and the reading "=0" appears. The operation is validated.

159 Chapter 2 OPERATING PRINCIPLE I- COMPRESSOR MANAGEMENT FUNCTION The compressor is controlled by the BSI. It takes into account: • the compressor engaging request (A/C), • the icing up safety of the evaporator, • the air conditioning pressure, • the engine speed, • the engine coolant temperature, • the dialogue with the engine management ECU.
160 Chapter 2 B - EVAPORATOR ICING UP SAFETY DEVICE The evaporator icing up safety device defines the rules for engaging and cutting off the compressor depending on: • evaporator temperature, • external temperature.
161 Chapter 2 C - AIR CONDITIONING PRESSURE SAFETY DEVICE The BSI cuts off the compressor in the event of: • high pressure (risk of damaging the circuit), • low pressure (probability of a leak). Detection is performed by a 4 level pressure switch.
162 Chapter 2 Example: Engine speed as a function of time.
163 Chapter 2 E - ENGINE COOLANT TEMPERATURE COMPRESSOR CONTROL If the engine coolant temperature is too high, compressor operation is controlled by the BSI. The compressor is forbidden for a coolant temperature above 112°C. It is authorised to re-engage if the coolant temperature is below 109°C and if the previous cut-off due to coolant temperature was more than one minute ago. Example: coolant temperature as a function of time.
164 II - Chapter 2 ADDITIONAL ELECTRIC HEATING FUNCTION Function: For DW10TD engines (HDi), heating resistors are placed in the engine cooling circuit. This allows a sufficient heat source to be obtained to operate the air conditioning, despite the slow rise in engine temperature. Functional description: The engine ECU requests the additional heating depending on the following information: • coolant temperature, • external temperature (through engine inlet).

177 Chapter 1 III - OPERATION A - SYSTEM COMPONENTS Transponder: An analogue unit, located in the top of the ignition switch, sends a signal to the ignition key. This is fitted with a responder label which disrupts the signal emitted by the analogue unit. The modification to the signal allows the analogue unit to transmit the key code (responder label) to the BSI. Built-in Systems Interface: The BSI decodes the signal sent by the label.

179 Chapter 2 OPERATING PRINCIPLE OF THE FACTORY FITTED ANTI-INTRUSION ALARM I- FOREWORD Note: The factory fitted alarm is only available on the XSARA. The role of this function is to protect the vehicle against intrusions. Protection is provided by Perimetric and Volumetric monitoring. This alarm is not multiplexed as it is inside the BSI. All the sensors and actuators for this function are therefore connected directly to the unit.

181 Chapter 2 III - OPERATION A - OPERATING MODES The anti-intrusion alarm has 3 operating modes: MODE DESCRIPTION Armed mode Vehicle protected Disarmed mode Vehicle not protected Triggered mode Signalling an intrusion B - ARMING / DISARMING Arming The vehicle is protected only when it is deadlocked using the HF remote control. When armed, an intrusion or cutting the supply will cause the alarm to be triggered for 30 seconds.
182 Chapter 2 C - PERIMETRIC PROTECTION This protection monitors: • the doors, • the boot, • the bonnet, • the + accessories position, • the + ignition on position, • the + battery position. Perimetric protection is active 5 seconds after the alarm is armed. Case of one of the doors or boot or bonnet not correctly closed • The siren emits a sound for 0.2 seconds. • A timer is started: the user has 45 seconds to close the door, boot or bonnet. After this, perimetric monitoring is active.
183 Chapter 2 D - VOLUMETRIC PROTECTION This protection monitors the volume of the passenger compartment. It is active 45 seconds after the alarm is armed. 1 - Triggering volumetric protection: An intrusion is detected by the ultra sound sensor module. All significant variations in passenger compartment volume trigger the alarm.

187 Chapter 3 III - OPERATION A - PERIMETRIC PROTECTION The information about the status of the doors, bonnet and boot is acquired by the interior lamp control: if, after a time, the interior lamp or lamps are extinguished, the vehicle is considered to be closed. If the bulbs in the interior lamps are missing or faulty, the alarm is not affected: the information is taken from the command sent by the BSI.
188 Chapter 3 2 - Arming The LED flashes during the volumetric protection timer at a frequency of 25 Hz, then at a frequency of 1 Hz until it is disarmed. If volumetric protection is cancelled, the LED flashes immediately at a frequency of 1 Hz until it is activated. a - Triggering To view the reason why the alarm was last triggered, the vehicle must be locked and then unlocked quickly.
189 Chapter 3 D - SPECIFIC OPERATIONS IMPORTANT: When fitting an after-sales alarm, the BSI must be programmed to prevent the indicators from being controlled when the doors are locked/unlocked. In this case, the alarm controls signalling. Opening the vehicle with the key: If the vehicle is opened using the key, the alarm is triggered. To disarm the alarm, the following procedure must be performed: enter the "EMERGENCY CODE".
190 Chapter 3 Fitting / removing the alarm: When fitting the alarm, disconnect the battery. After the operation: • Reconnect the battery, • Enter the "EMERGENCY CODE", • Switch on the ignition for 10 seconds, • Switch off the ignition. The siren is activated. IMPORTANT: When working on the alarm, the battery must be disconnected throughout the operation. Switching off the self powered siren: • Disarm the alarm, • Disconnect the connector from the siren.

203 Chapter 2 RADIO OPERATING PRINCIPLE I- SWITCHING ON / OFF A - GENERAL DESCRIPTION The radio is switched on and off by: • pressing the "ON" button on the front of the radio, • switching the ignition on or off*, • inserting a CD when the + accessories is present (RD2). * If the radio was on before the ignition was switched off (vehicle stationary), the radio will work when the + accessories reappears.
204 II - Chapter 2 RADIO ANTI-THEFT FUNCTION The radios do not have an LED which flashes when the vehicle is stationary. The anti-theft protection device is provided in the form of an identification code. It consists of the last 8 characters of the VIN, memorised by the BSI and the radio. Note: Radios are supplied by the Replacement Parts Division with a memorised VIN code. When operating, the radio's VIN code is compared with that of the BSI.
205 V- Chapter 2 THERMAL PROTECTION The radios have dynamic maximum volume limitation strategies, which depend on the rise in temperature in the units. Note: RD2 radios limit the volume without altering the volume displayed on the screen. RB2 radios only display the change in volume if the user performs a voluntary action (reduction in maximum volume from 30 to xx). VI - CONFIGURATION All new systems which have not been programmed will not be recognised by the system and will therefore not work.
