Intermittent Loss Of Rear Door Operation

Good evening everyone. Here is a case Study I did on a 2011 New Flyer 40 ft Bus that had a intermittent loss of control from the Rear Doors. While going down the road and at stops sometimes the Driver would complain of the Rear Door Open light coming on the Dash and then noticing he lost control of the rear doors.

For this Case Study I did some Videos of what I found and I also did some screen recordings showing how I used both of my Pico Scopes together to diagnose this problem.

This Case Study in my opinion really proves that you have to have a Scope now to fix the Vehicles of today.
