Notes:
Ignition coils and power output stage are a
common part.
Primary resistance of ignition coils cannot be
measured.
Secondary resistance must first be measured
with the ignition wires connected to the ignition
coils via the spark plug connectors of the
corresponding cylinder (This measurement will
include measurement of the shielded
resistances of the ignition wires).
- Disconnect 5-pin connector from ignition coils.
Check ignition coils (-N-, -N128- and -N158-)
- Pull the ignition wires from the spark plugs.
- In order to perform a resistance measurement, connect multimeter
between both spark plug connectors of the respective ignition circuit to
be checked.
