Measurement Method

Measurement Method:

1. Disconnect the ignition power transistor connector and connect the special tool (Harness connector: MB991348) in between. A terminals should be connected.
2. When observing the No. 1 - No. 4 cylinder group, connect the primary pick-up of the analyzer probe to power transistor side connector terminal (13).
For the No. 2 - No. 5 cylinder group, connect to terminal (12) and for the No. 3 - No. 6 cylinder group, connect to terminal (11).
3. Ground the primary pick-up ground terminal.
4. Clamp the spark plug cable with the trigger pick-up.

NOTE:
1. Clamp the spark plug cable of cylinder No. 1, No. 3 or No. 5 which belongs to the same group as the cylinder to which the primary pick-up is connected.
2. The waveform of any cylinder in the same group appears from the left side of the screen.
