Was supposed to be in Glamis this weekend but club volleyball got in the way. Decided to get my 4 wheel fix in the jeep today. Hit the Cleghorn trails. Had a great time and the Jeep never ceases to amaze me.
I just went through an issue like this. Check the blue plug that connects into the brain. Any kind of corrosion will stop it from connecting. I had to swap the plug and it worked great since.
