U0322 Software Incompatibility With Body Control Module

Check engine lightUsually off

Limp modeNo

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.

Likely causes

BCM replaced or swapped without loading vehicle configuration
BCM updated while a connected unit such as a headlamp module kept old software
BCM programming interrupted by low voltage or lost connection

Symptoms

  • 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
