Measure the voltage between "Power" terminal of "IGNITION COIL" harness connector and chassis ground at IG key "ON" after disconnecting "IGNITION COIL" connector.

Is the measured voltage value normal ?

	▶ Go to "Ignition coil control circuit inspection" procedure as below.
	▶ Check for open/poor connection/short to ground between "IGN COIL" fuse on "E/R FUSE & RELAY BOX" and "Power" terminal of "IGNITION COIL" harness connector.

Connect the red tongs of LED circuit tester to battery (+) and the probe of it to "Control" terminal of "IGNITION COIL" harness connector after disconnecting "IGNITION COIL" connector.

Perform the actuation test of "Ignition coil #1~#6" by using GDS.

Check LED lamp of the circuit tester while performing the actuation test.

Does the LED lamp of the circuit tester blink normally ?

	▶ Go to "1st ignition signal waveform inspection" procedure as below.
	▶ Check for open/poor connection/short to ground between "Ignition Coil Control" terminal of "ECM/PCM" harness connector and "Control" terminal of "IGNITION COIL" harness connector.

Select oscilloscope function on the GDS and Connect channel "A" of the VMI to "Control" terminal of "ECM/PCM" harness connector.

Measure the signal waveform of the 1st ignition at IG key "START".

Is the measured 1st ignition signal waveform normal ?

	▶ Click on "Spark plug" item for more details.
	▶ Check for open/poor connection/short to ground between "Ignition Coil Control" terminal of "ECM/PCM" harness connector and "Control" terminal of "IGNITION COIL" harness connector.
