4 1 Guarantee WARNING : The change of a BSI under guarantee is subject to a request for approval from your Technical Assistance team. 2 Contacting your Assistance team 2.1 Introduction Before contacting Assistance, please be ready with the following elements: s. of the procedures implemented (G01 to G11), The sequence used (S0x), The stage you have reached (depends on the procedure being used). 2.2 Example of the type of information you need to provide You have implemented procedure G10 (Wipers), sequence S06 corresponding to «Check on the rear screen wiper function» and you have arrived at stage N 2.1 in the flow chart. You will say to your contact : G10 - S Recommendations - precautions Before any consequent operation, it is essential to check : the battery voltage, the fuses, that the shunt is correctly positioned on the BSI (the shunt should be in the Customer position), that the BSI is not in back-up mode (see : Preliminary checks on the BSI below).

5 4 Functions To indicate to the driver that the oil level is correct, the BSI calculates the level to be displayed, from four measurements of the oil level. The oil level is measured each time you switch on the ignition, this being confirmed by an «Oil» warning lamp. 4.1 Features of the «Oil» warning lamp Features of the warning lamp «Oil» : Citroën C4 : the «Oil» warning lamp is located on the instrument panel below the indication of distance/speed, New Look C5: the «Oil» warning lamp is a display on the odometer, following the display of the mileage remaining to the next service. 4.2 Features of measuring the oil level The measuring of the oil level is done by the injection ECU on : 2.0 petrol engine (Engine plate : RFJ) 1.4 petrol engine (Engine plate : KFU) On other engine versions, the oil level is measured by the Engine Relay Unit (BSM). 4.3 Checking instructions To guarantee the validity of the indication of oil level, apart from when on economy mode, perform the following operations : Switch on the ignition (without starting the engine), Wait 15 seconds, Switch off the ignition, Wait at least 3 minutes (without opening the doors or leaving any doors open) in order to allow the BSI to go to sleep, Switch on the ignition (without starting the engine), te the behaviour of the «Oil» warning lamp on the instrument panel. Page 5 / 11

6 Display by the «OIL» warning lamp Possible causes Flashing display of «OIL». Oil level alert. Oil level too low (0% to 11%). Oil level too high (over 100%, oil level above the maximum level on the manual gauge). Fixed display of «OIL --». Oil level in process of being measured. Fixed display of «OIL OK» Oil level between 12% and 100%. Flashing display of «OIL --». Display invalid (measurement problem). if «OIL» is flashing, the message «Engine oil level alert» appears on the multifunction screen. 5 Configuration A certain number of configuration parameters are memorised in the BSI : parameter «Oil level sensor option» (Absent / Present), one parameter relates to the engine version : Citroën C4 : parameter «Selection of engine oil gauge table» (2.0 16V (138hp) petrol, V petrol, V (180hp) petrol, V petrol, V (143hp) petrol, 1.6 HDi, V HDi). Citroën New Look C5: parameter «Oil gauge law engine version» (3.0 (V6) petrol, 2.0 petrol, 1.8 petrol, 2.0 HDi, 1.6 HDi, 2.2 HDi), parameter «Origin of the oil level information» (Engine Relay Unit, Engine ECU), parameter «Condition of oil level measuring» (Engine stopped, Engine running). You can access the parameters after starting communication with the BSI using a diagnostic tool and selecting the menu «MANUAL PROGRAMMING» then «CONFIGURATION», «OIL LEVEL GAUGE LAW». Page 6 / 11

7 6 [G08][S00] Preliminary checks on the BSI. Stage 1 Identification of a BSI in back-up mode: - First case: When the ignition is switched on and the lighting stalk is in position 0, the vehicle s sidelamps (front or rear or both) come on. - Second case: With the engine running, the dipped beam headlamps come on, the windscreen wiper operates in intermittent wipe or in slow speed. Stage 2 Does the BSI show symptoms of being in back-up mode? Stage 4 Check the fuses, the supplies of the BSI repair if necessary Stage 3 End procedure Stage 5 Using a diagnostic tool, start communication with the BSI, select the menu «IDENTIFICATION» Are you able to read the software edition of the BSI? Is it coherent with the normal software editions (software edition strictly higher than 01.00)? The BSI is not responding to the diagnostic tool Go to stage 6 Stage 5.1 End procedure Check the link between the diagnostic tool and the diagnostic socket, the condition of the various connections and the working of the communication interface of the diagnostic tool. If everything is in good condition, replacement of the BSI is authorised. Go to stage 10 Page 7 / 11

8 Stage 6 Is the BSI new? (coming from Replacement Parts) Stage 7 End procedure Replacement of the BSI is authorised Stage 8 Has the BSI been downloaded previously? Stage 9 Repeat the downloading of the BSI at least three times. Go to stage 10 After the third attempt, replacement of the BSI is authorised. Page 8 / 11

9 Stage 10 1) Using a diagnostic tool, start communication with the BSI. Select the menu «CONFIGURATION» then «Customer options», configure the parameter «Type of daytimerunning lamps» to «no daytime-running lamps». 2) Deactivate the daytime-running lamps and automatic lighting of headlamps, using the personalisation menu (MENU button on either the steering wheel or the radio). 3) Switch on the ignition (+APC). te the functioning status of the front and rear sidelamps as well as that of the windscreen wipers. The front and rear sidelamps are on and the windscreen wipers are operating on slow speed or intermittent slow speed. One of the following conditions is not met : the front and rear sidelamps are on the windscreen wipers are operating on slow speed or intermittent slow speed. Go to stage 14 Stage 11 Action the hazard lamps button. Does the led on the button light up when the button is actioned? Stage 13 Using a diagnostic tool, start communication with the Airbag ECU. Select the menu «Identification» Stage 12 The BSI is at fault. Replacement of the BSI is authorised Are you able to read the components of the identification screen of the Airbag ECU? Stage 13.2 Direct your searches to the switch module under the steering wheel (or the FCC steering wheel) and to the multiplexed BODY CAN network. If the BODY CAN network is in good condition, replacement of the BSI is authorised. Stage 13.1 If the link between the switch module under the steering wheel and the BSI is in good condition, replace the switch module under the steering wheel or the FCC steering wheel (control block under the steering wheel). The BSI is not the cause, replacement is prohibited. Page 9 / 11

10 Stage 14 Switch on the ignition. te the functioning status of the front and rear sidelamps as well as that of the windscreen wipers. One of the following conditions is not met : the front and rear sidelamps are off the windscreen wipers are operating on slow speed or intermittent slow speed. The front and rear sidelamps are off and the windscreen wipers are operating at slow speed or intermittent slow speed. Stage 14.1 The Engine Relay Unit is at fault. Direct searches to this ECU. WARNING : Configure the parameter «Type of daytime-running lamps» in the BSI as it was originally. Stage 16 Switch on the ignition The front sidelamps are on and the rear sidelamps are off? Stage 17.2 Replacement of the BSI is authorised Stage 15.2 Direct your searches to the link between the switch module under the steering wheel (or the FCC steering wheel) and the Engine Relay Unit, as well as to the Engine Relay Unit itself. WARNING : Configure the parameter «Type of daytime-running lamps» in the BSI as it was originally. Page 10 / 11

11 7 [G08][S01] The electric oil gauge does not show any oil level Operations to be carried out : check the configuration of the BSI (Parameter «Oil level sensor option» (Absent / Present), parameter «Origin of the oil level information» (Engine Relay Unit, Engine ECU), check the resistance of the engine oil level sensor (approx. 10 ohms). check the continuity of the electrical harnesses, check the wiring. WARNING : The BSI is not the cause, replacement is prohibited. Page 11 / 11
