I have look and look but can't find. How do I check a electronic control module to see if it is good or not? Thanks for any help you have. |

There used to be an old Mopar EI checking tool (basically plug it in and see if the lights light up for a good EI). Not sure if anybody ever ended up with one of those boxes...it's kind of a limited use item to have around the garage. -D.Idiot |

I just toss it into a bucket of water. If it sinks, I flip a coin, heads install a unit that I know works, tails I install a unit I know works, and than discard the wet one. Just kidding, I don’t really use water… One thing you can check is that the unit has a good ground, necessary for proper operation. The spare unit is your test device… |

So here is another question on a related subject (if I may but in ). Should I be getting shocked (feeling electrical current) from my ECU when my fingers are touching both the center metal "button like device" and the heat sink? I say no but then again, there are a lot of other people here that are more knowledgeable on this subject than me.

Short answer is yes-Just like the one you get across the points and for the same reason (has to do with collapsing magnetic fields/lines of force that make the big spark) |
