EG–415 ENGINE – 2JZ–GE ENGINE TROUBLESHOOTING 4 Check voltage between terminal IGT of engine control module connector and body ground. START SST ECM B 57 IGT BE6653 FI0614 P Connect SST (check harness "A"). See page EG–404) SST 09990–01000 C Measure voltage between terminal IGF of engine control module connector and body ground when engine is cranked. OK Voltage: 0.5 — 1.0 V (Neither 0 V nor 5 V) Reference INSPECTION USING OSCILLOSCOPE IGT signal waveform 2 V/Div. IGT 0 V IGF 0 V 5 m sec/Division (Idling) FI6605 • During cranking or idling, check waveforms between terminal IGT and E1 of engine control module. HINT: The correct rectangular waveforms are as shown. OK NG Go to step 8 . 5 Check voltage between terminal 3 of igniter connector and body ground. ON and START BE6653 FI6438 P Disconnect igniter connector. C Measure voltage between terminal 3 of igniter connector and body ground, when ignition switch is turned to "ON" and "START" position. OK Voltage: 9 — 14 V OK NG Check and repair igniter power source circuit.
