Ignition System Diagnosis
The ignition system on modern BMW engines consist of one ignition coil per
cylinder. This arrangement is
known as RZV, or Direct Stationary Ignition. The ignition coil receives fused
power usually from the DME
main relay or IVM (N62).
The ignition coil primary circuit is controlled (triggered) by
Notes On Handling Optical Fibers
CAUTION: To avoid damage when handling optical fibers, comply with the
following
points:
The minimum permitted bending radius is 25 mm
Do not subject optical fibers to compressive and tensile load
Protect optical fibers against the effects of heat > or =85ºC
(e.g.
during welding work, dr
