FS2 – Engine starting piloting If starting conditions are in place: Piloting of the starter relay by pressing the engine starting button. Inhibition of the control upon release of the button or upon starting of the engine (engine speed more than 475 rpm). Protection of the starter by blocking of piloting if the engine has not started after 10 secs. Time-delay of 3 secs between 2 starting attempts to avoid overheating of the starter. Blocking of the control if 3 starting attempts unsuccessful. FS3 – Engine STOP fault information piloting Decoding of a message sent by the “VECU” via message carrier J1587. Piloting of a warning light in case of fault (copying of the information fed back by the message carrier. Fault considered as blocking and conditions starting authorization. FS4 – Engine SERVICE fault information piloting Decoding of a message sent by the “VECU” via message carrier J1587. Piloting of a warning light in case of fault (copying of the information fed back by the message carrier). Fault considered as blocking and conditions starting authorization. FS5 – Engine speed information piloting Decoding of a message sent by the “VECU” via message carrier J1587. Activation of a frequential output to pilot a “VDO” rev counter. The “VDO” rev counter gives the same engine speed displayed in-cab. RENAULT V.I. 06/02 2 DT List of system functions (continued) FS6 – Engine faults information piloting Detection of box faults: Communication problem. Short-circuit or absence of charge at outputs. Engine starting problem. Signalling of the fault number upon pressing a pushbutton. Warning light bulbs test (steady illumination) upon pressing the button but without any fault to signal. List of “CECU” box faults: 1 – Box inoperative. 2 – Communication fault. 3 – Starting time-out or gear engaged. 4 – Starter fault at output. 5 – Engine STOP output fault. 6 – Engine SERVICE output fault. FS7 – Tachograph speed signals amplification Amplification of “corrected speed” and “4 pulses per metre” signals coming from tachograph. 20 mA output for piloting different ECUs. FS8 – Starting functionalities validation Detection of the state of a switch at a dedicated validation input: Switch closed (input at master switch after-ignition +): all functionalities are operational. Switch open: engine starting is inhibited, together with management of engine STOP and SERVICE faults – the rest is functional. FS9 – Engine stopping Allows the engine to be stopped by an auxiliary button independent of the “CECU” box. Meets the functionalities managed by the EECU.
