Elevel ECU

Seems as if my Accuair elevel ECU is fried...anyone know of any trouble shooting I can do? Nothing will turn on. It all worked not long ago. Thanks

Re: Elevel ECU

Here's the manual. I would check the 2 fuses for the unit. Check to see if you are getting 12V to the battery wire, 12 V on the Ign. wire to the unit, and check the ground wire making sure it has clean contact to ground.

Re: Elevel ECU

Thanks for the reply...I did all that. All my wiring is good. I'm fairly certain the ECU is fried as I've read that jumpstarting the truck is not liked by the ECU. Read that after I jumpstarted the truck. Thinking there's a small chance someone has had this issue and can tell how to fix it since Accuair is shut down.

When I put my system in, my buddy who had previously installed a few accuair setups, expressly told me not to boost the truck with the system hooked up as it would fry the ecu and the only fix was a replacement ecu.

I trust his information as he is very good at what He does.

Re: Elevel ECU

Pretty sure this is the problem. Only wish Accuair would have put that in their manual somewhere. Woulda been helpful. Too late now I guess. For the ECU and for me since Accuair folded up. Any other suggestions to get the truck back up in the air?

Re: Elevel ECU

Yeah, this is crazy that this is not noted anywhere. I'm sorry to hear this happened to you, but at the same time, thanks for putting this out there - might save some of us ecu issues.

So I wonder if this would be the same if you put your truck on a trickle charge?

Re: Elevel ECU

It seems as if any fluctuation can damage the ECU. Which if you think about it is kinda crazy for an auto part. I can't find another ECU anywhere now. Not sure what I'm going to do. Anyone ever troubleshoot these things? Like open them up?
