Ignition power transistor control signal
MEASUREMENT METHOD
1. Disconnect the ignition power transistor connector, and connect the special tool (test harness: MB991348) in between. (All terminals should be
connected.)
2. Connect the analyzer special patterns pickup to the ignition power transistor connector terminal 2 (No.2 - No. 3) and terminal 7 (No. 1 - No.4)
respectively.
ALTERNATE METHOD (TEST HARNESS NOT AVAILABLE)
1. Connect the analyzer special patterns pickup to ECM terminal 10 and connection terminal 23 respectively.
