Now if you can do electrical diagnostics, I can forward that info as well.

do i have to take to a shop to perform the fast learn or can i reset the ecm
Expert:  Chris (aka- Moose) replied 3 months ago.

You can do it at home by disconnecting the auxiliary battery. Then disconnect the primary battery and hold those cables together for one minute. Then 30 minutes later reconnect both batteries.

Hello again Chris here,

  • I am following up with you to see if you got everything you needed from my answer. We're you pleased with my help?
  • If you were not pleased with my help, please let me know by replying so I can help more.
  • This post is coming up on the 7 day mark where it times out. When a post times out, that means it's no longer on my active list (you reply and I may never know it.)

Thanks Chris
