Ignition System

NOTE: Due to the complexity of the fuel injection system, the ignition test is not suitable for HFM-SFI engines, .





General Information
With this test program, all existing constant (non-intermittant) ignition system faults can be recognized by their numerical value.
- For intermittant faults, the oscilloscope should be used. The numerical values can be read from the oscilloscope.
- See "Test and Adjustment Data". Test and Adjustment Data [Specifications]


6-Cylinder engine, Engine 103:
During the Ignition system program the following data must appear on the engine analyzer:

Sample 6-Cylinder Engine:

The data shown is a representative example of a 6-cylinder engine. The data in actual tests will vary.


8-Cylinder engine, Engine 116/117:
During the Ignition system program the following data must appear on the engine analyzer:





Failure on cylinder 3: Electrode gap too small, for further information see scope pattern.
