• 11033825Jun 12, 2026Transmission and drivetrain, Other or unknown. This bulletin supersedes 26-2091. Reason for update: To update the production cutoff date for Transit vehicles. Some of the vehicles listed in the Model statement above may exhibit an illuminated MIL with DTC P2C90 stored in the powertrain control module (PCM). This may be due to the software in the PCM.
• 11033848Jun 11, 2026Electrical system, Other or unknown. Some 2026 Transit customers may request additional keys to be programmed to the vehicle. The maximum number of keys that are allowed to be programmed is now 4. This is due to the architecture of the body control module (BCM) changing that now limits the number of keys programmed. Ford Diagnosis and Repair System (FDRS) has been updated to reflect that 4 keys are the maximum number of keys to be programmed.
• 11033832Jun 10, 2026Electrical system, Lane departure. Some 2026 Transit Chassis Cab/Cutaway vehicles that were ordered with a blind spot information system (BLIS) kit (minor feature code HLLAM) may not be able to connect the harness to the vehicle after the upfit has been completed. This may be due to the harness being too short in length. To correct this condition, order a new BLIS kit harness using service part number RK3Z-15K868-A.
