Airbag parking brake and check engine lights stay on!!

0 votes
Well until you disconnect the t harness it throws a check engine light airbag light and parking brake on the dash and car will not start!! Not even with the key and when you open the drivers door the factory alarm goes off also the PATS indicator light doesn't come on at all until the t harness is unplugged and taken out of the circuits then everything goes back to normal!! Is there any special programming for the Fusion hybrid?? Also when it attempts to start the car it's like it's not firing up the crank wire because the car won't start but everything else comes on!!! Do I need to interrupt the ground to the headlight switch?? I wouldn't think this would be the cause but I'm running out of ideas!! The t harness I'd a THAR for-1 I've tryed reprogramming it multiple times and have checked the firmware setup etc and everything seems to look good is it possible the module is defective or maybe one off the diodes in the t harness??? Even with parking lights disconnected it still acts the same way!!

Ford Fusion do not connect the Lock and Unlock wires listed in the installation guide. Those connections are being removed in the next updates to the guide. I know this makes no sense to your current problem / question.

Also, grabbing the wrong door pin wire and /or reversing it will cause odd things. There are too many wires in Ford vehicles that are either purple/green or green/purple and it's extremely easy to use the the wrong one.

Lock wires were never connected in the first place!! It controls them fine through the canbuss!!

If the t-harness is connected to the vehicle but the EVOALL is completly disconnected to you still get the same problem ?

Just connect the t-harness connectors to the car and see if the car start
