How to Test Ignition Coils | Ignition Coil, Wiring & ECM Internal Diagnosis

In this video I show you how to test the ignition coil when there is an ignition coil fault code or misfire. I explain the ignition coil wiring diagram & how to find the pins locations and wires. I also explain how to remove the ignition coil and test the primary and secondary winding inside the coil. Then I explain how to test the ignition coil power supply and control line. Then I show you guys how I test the ECM internal circuit if the ignition coil malfunction is caused by ECM internal error.

Po302 on my 2006 Subaru sti. Have done everything I can think of. Swaps, compression and leakdown test, vacuum leak test, crankshaft and camshaft position sensor test and cleaning. Replaced both denso o2 sensors. Tested cylinder 2 connector cam pulsing signal with a noid test kit.

Hi my friend. I assume that you have already swapped the ignition coil with another cylinder. Considering what you have done so far, the next step could be checking the injector #2 and ignition coil #2 wiring. Have you checked the spark on the ignition coil?

Swapping coils was the go to . But there are times a bad coil can short driver in computer so swapping will short next driver for that cylinder. But ether way you will meed a computer. DSO wins the day 👊🏻

Will you check transıstors or other electronic materials

[@AutomotiveDiagnosis]

Yes, that’s necessary if wiring and ignition coil are good and we still have a code.

[@arthurmadazichabinga1450]

This is beautiful. And how do you get access to the repair manuals (manufacturers).

[@AutomotiveDiagnosis]

Hi my friend. For this car I had a software called GDS which provides all diagrams and manuals for Kia and Hyundai. We are also trying to make all our diagrams available for you guys for free. Very soon hopefully.
