• 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.

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.
