Removing-refitting electronic control unit

REMOVING-REFITTING ELECTRONIC CONTROL UNIT

The electronic control unit is located under the glove compartment (right hand side). To remove the control unit proceed as follows:

• Undo the bolts fixing the control unit to the mounting bracket.
• To remove the multiple connector, pull the connector clip upwards.

There could be tension at the terminals not connected therefore no connections should ever be made because there is the risk of a short circuit with damage to the control unit.

The operations of fitting and removing the multiple connector should be carried out with the ignition switched off.

IGNITION COILS (0 221 504 006)

The "static advance" electronic ignition has been improved with a single coil for each spark plug (SINGLE COIL); in addition, the power modules are contained inside the control unit; in practice this solution eliminates the H.T. circuit, further increasing reliability and safety and decreasing the risk of interference due to the high tension leads and connections. They are normal coils which increase the tension of the impulse sent to the spark plugs: each individual coil, located on the cylinder head, directly supplies a spark plug without intermediate H.T. leads.
