Some 2020-2022 Transit vehicles may experience intermittent operation of the power sliding door (PSD) which may not open/close properly. It can still be closed manually. Diagnostic trouble code (DTC) U201A may or may not be present in the door control module H (DCMH). The PSD may partially actuate with each press of the remote, dash button, or door handle actuation. To correct the condition, follow the Service Procedure to replace the latch, install conical washers and adjust the door.
