KA AI 01 CONTENTS GENERAL ENGINE IDENTIFICATION REMINDER OF THE PRINCIPLE OF OPERATION NOMENCLATURE - WIRING DIAGRAMS FAULT FINDING PROCEDURE SEQUENCE TO BE FOLLOWED PRECAUTIONS TO BE TAKEN FAULT FINDING CHARTS GENERAL ENGINE IDENTIFICATION The engine is identified by plates riveted to the cylinder block: (a) Riveted plate bearing the engine type: RFZ (b) Riveted plate bearing the engine number REMINDER OF THE PRINCIPLE OF OPERATION The management of petrol injection is identical to that of the XU10J2Z engine (brochure ref. KA IR 01). The mapped type ignition is managed by the same control unit as the injection. The information transmitted by the various sensors, exploited by the control unit, is used to control ignition and injection. The double coil (two primary and two secondary circuits) with four high tension outlets is controlled by the ignition amplifier module. This is not yet integral with the control unit, and controls each of the two circuits alternately.

Injection-ignition test warning lamp 7. Injection-ignition test connector 8. Fuel tank 9. Fuel pump 10. Fuel filter 11. Pulsation damper 12. Distribution pipe 13. Pressure regulator 14. Injector 15. Inlet air thermistor 16. Coolant thermistor 17. Engine speed sensor 18. Ignition coil 19. Spark plug 20. Injection relay 21. Fuel pump relay 22. Ignition module 23. Canister 24. Canister purge valve 25. Canister purge cut-off solenoid valve 26. Idle regulation valve For further information on the operation of this system, refer to the "principle of operation" brochure ref. LE AD 02.

KA IR 01, taking account of the modifications. PRECAUTIONS TO BE TAKEN Use EUROSUPER unleaded petrol RON 95 minimum FAULT FINDING CHARTS Introduction of the double coil entails changes to some charts to some charts because of modifications to the harnesses and components: Checking the presence of high tension at cylinders 1-4 and 2-3: see page 7 Check of ignition coil : see page 8 Check of ignition coil : see page 8 Check of the ignition amplifier module 1105: see page 11 There is no change to the fault codes and the other fault finding charts: see the list in brochure ref. KA IR 01 page 26 NOTE When brochure ref. KA IR 01 calls for an ignition check, refer to pages 7, 8 and 11 of this supplement
