Got it. There is a troubleshooting flowchart to check this ignition system and not individual component tests. You had asked for procedure to check the module and the ignition sensor. That's really not the way it's troubleshot. It's troubleshot by following the flowchart. So my next question is have you seen the flowchart but confused by any step on it, or do you need the flowchart?
