Pinpoint Test E: The Power Seat Does Not Move Horizontally/Vertically
- E1 CHECK THE SEAT OPERATION WARNING: The restraint system diagnostic tool is for restraint system repair only. Remove from the vehicle prior to road use. Failure to remove could result in personal injury and possible violation of vehicle safety standards.
