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.

NOTE



Sealed foolproof connectors with different colours fitted to the oxygen sensor 1350:

� red connector in place of black for the heater � white connector in place of blue for the signal

This modification will not take effect at the same time for the connectors at the harness and sensor ends.

* According to equipment

FAULT FINDING PROCEDURE

SEQUENCE TO BE FOLLOWED

When fault finding on this system, it is imperative to follow the sequence shown on page 10 of brochure ref. 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 1 1135: see page 8 � Check of ignition coil 2 1135: 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
