The power module is integrated into the fuel injection control unit.
The ignition system uses the same sensors as the fuel injection system.
The ignition coils (four, corresponding to the number of cylinders) are attached directly to the spark plugs using a bolt on the cylinder head cover.
The fuel injection control unit supplies power to the ignition coils sequentially in pairs:
- – via terminal C M4 for ignition coils of cylinders 1 and 4;
- – via terminal C M3 for ignition coils of cylinders 2 and 3.
Removal
Remove the upper engine covers.
Disconnect the wires from the battery terminals, starting with the negative terminal.
Disconnect the wire connectors from the ignition coils and remove the bolts securing them (Fig. 2).
Using a 10 mm socket wrench (or an 8 mm socket, depending on the configuration), loosen the coil mounting bolt.
Remove the mounting bolt. Coils
Remove the rod coils, paying attention to any visible defects on the coil insulators.
There should be no cracks or burn marks (from spark flashover) on the coil housing.
ATTENTION
Damaged socket connectors must be replaced.
Installation
Installation is the reverse of removal.
Apply to all four coils Apply 2 mm diameter "graisse fluoree" grease to the inside circumference of the high-voltage cable boot.
Replace the ignition coil O-rings if necessary.
Tighten to the specified torque:
- – ignition coil mounting screws (15 Nm);
- – battery cover mounting bolts (4 Nm).
