Pinpoint Test I : The Power Seat Does Not Move Horizontally/Vertically - Driver, With Manual Recliner

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The airbag warning indicator illuminates when the correct RCM fuse is removed and the ignition is ON.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

  1. I1 CHECK THE HORIZONTAL MOTOR FOR CORRECT OPERATION
