Oscilloscope Patterns and Waveforms

MEASUREMENT METHOD
1. Remove the ignition coil connector and connect the special tool (harness connector: MD998464) in between.
2. When observing the No.1 - No.4 cylinder group, connect the primary pickup of the analyzer probe to the ignition coil side connector terminal No.2 (black clip on the special tool).
For the No.2 - No.5 cylinder group, connect to terminal No.1 (red clip), and for the No.3 - No.6 cylinder group, connect to terminal No.4 (white clip).
3. Ground the primary pickup ground terminal.
4. Clamp the spark plug cable with the trigger pickup.

NOTE:
1. Clamp the spark plug cable of cylinder No.1, No.2 or No.3 which belongs to the same group of the cylinder to which the primary pickup is connected.
2. The wave-form of any cylinder in the same group is displayed on the left side of the screen.
