2.6.6. Removal and installation of coils of ignition (all engines)

The power module is built in EBU of system of injection. In system of ignition the same sensors, as in system of injection are used.

Fig. 2.276. Coil and spark plug

Ignition coils (four, on number of cylinders) are fixed directly on spark plugs by means of a bolt on a cover of a head of the block of cylinders (fig. 2.276).
EBU of system of injection gives food on ignition coils consistently on couples:
– through contact of C M4 for coils of ignition of cylinders 1 and 4;
– through contact With M3 for coils of ignition of cylinders 2 and 3.

Remove the top covers of the engine.
Disconnect wires from plugs from the rechargeable battery, since the negative plug.

Fig. 2.277. A detachment of blocks of wires from ignition coils: 1 – blocks of wires; 2 – bolts of fastening of coils

Disconnect blocks of wires from coils of ignition and turn off bolts of their fastening (fig. 2.277).

The damaged rozetochny parts of sockets are subject to obligatory replacement.

Installation is made as it should be, the return to removal.
Apply on all four coils of ignition GRAISSE FLUOREE lubricant (diameter of 2 mm) on an internal circle of a cap of a wire of high voltage.
Replace if necessary sealing rings of coils of ignition.
Tighten the required moment:
– screws of fastening of coils of ignition (15 N · l);
– bolts of fastening of a cover of the rechargeable battery (4 N · м).
