U0322Software Incompatibility With Body Control Module
- Generic OBD-II code · Network
- How the car detects it
- The body control module switches lighting, locks, wipers and many comfort functions and often holds configuration data used by other units. U0322 tells that a controller has found the BCM software or setup unfit for the vehicle. The code without a letter is meant for cars with one body controller; where two are fitted, U0331 names body control module A and U0339 module B. No manufacturer documents U0322 publicly. Ford shows the kind of mismatch on 2022 F-150 trucks (SSM 51591): following a software update of the BCM one or both headlamps could stay dark, sometimes with B14E5:08 or B14E7:08, because the LED headlamp module did not work with the new BCM software; Ford brings the BCM to the latest level and replaces the LED module. U0140 is lost contact, U0422 invalid data. Body functions fail, no MIL.
- What you may notice
- Headlamps, interior lights or wipers work wrongly or not at all
- Central locking or remote key functions unreliable
- Several body codes stored at the same time
- Likely causes
- LikelyBCM replaced or swapped without loading vehicle configuration
- PossibleBCM updated while a connected unit such as a headlamp module kept old software
- RareBCM programming interrupted by low voltage or lost connection
