IGNITION COIL AND POWER TRANSISTOR
Power transistor control signal
Measurement Method
1.
Disconnect the ignition coil connector, and connect the
special tool (test harness: MB991658) in between. (All
terminals should be connected.)
2.
Connect the analyzer special patterns pickup to terminal
3 of each ignition coil connector in turn.
Alternate Method (Test harness not available)
1.
Connect the analyzer special patterns pickup to
engine-ECU terminal 3 (No. 1 ignition coil), terminal 13
(No. 2 ignition coil), terminal 12(No. 3 ignition coil), terminal
4 (No. 4 ignition coil) respectively.
