The ignition advance is electronicallydetermined on the basis of the parameters recognised by the controller. Forthis
reason it is not possible to declare the reference values based on theengine rpm.
The ignition advance value is detectable any timeby the diagnostic tester dwg. 020460Y.
Using the stroboscopic lamp dwg. 020330Y it ispossible to check whether the ignition advance determined by the
injectionsystem matches that actually started on the engine.
Proceed as follows:
Remove the external transmission cover as
described in the
Automatic
transmission chapter.
- Remove the TDC reference inspection cap
between flywheel and cover housing. See the
Flywheel cover
? chapter.
- By the driving pulley nut, turn the engine to
find the alignment of the references to identify
the TDC
- Repeat the reference between driving pulley
and transmission cover
- Replace the inspection cap on the flywheel
side.
- Connect the diagnostic tester dwg. 020460Y.
