Why is my car starting and stopping and door is always open if module unplugged.

Question

2012 Ford fiesta lots of issues. Starts and shuts down over and over. If module is unplugged driver's door is always open.. headlights staying on when switch is off... This module is being installed by a 30 year certified technician

Answer 1

Vehicle will show door open with module disconnected because the circuit goes inside the EVOALL. Make sure yellow wire from 20 pin connector is connected to tharness.

Verify the parking light connection, a bad connection leave the headlight always on.

I'm a 6 years certified technician and never had any issues with a Fiesta.
