U0322 code meaning
Software Incompatibility With Body Control Module
What U0322 means
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.
U0322 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyWorkshop only
- Typical labor0.5 to 2.5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0322
- 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
Common causes of U0322
- Most likelyBCM replaced or swapped without loading vehicle configuration
- PossibleBCM updated while a connected unit such as a headlamp module kept old software
- Less likelyBCM programming interrupted by low voltage or lost connection
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0322 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 22 | The exact fault in that area. |
What to do next
- Note U0322 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0322
What does U0322 mean?
U0322 means "Software Incompatibility With Body Control Module". The body control module switches lighting, locks, wipers and many comfort functions and often holds configuration data used by other units. It is a generic code, so it means the same on every make.
Is it safe to drive with U0322?
U0322 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0322 fail an emissions test?
U0322 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0322 to fix?
Difficulty: workshop only. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will U0322 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
