U0322

Software Incompatibility With Body Control Module

Network / module software Generic OBD-II Medium

What it means

U0322 means the vehicle has detected that the body control module (BCM) is running software or a calibration that doesn't match the rest of the network. It usually appears after a module is replaced or reflashed. The BCM runs many electrical systems — lighting, locks, wipers — and on some vehicles gates starting, so a mismatch can make features misbehave, and occasionally cause a no-start, until the correct software is loaded.

Medium

Can I keep driving? Often drivable — but the body control module manages lighting, locks, wipers and more, and on some vehicles it gates starting, so features may misbehave and occasionally a no-start can result.

Common symptoms

What you'll notice

Warning lights and a U0322 stored, usually right after a module was replaced or reflashed
Electrical features misbehave — lighting, wipers, locks, windows, chimes
On some vehicles, no-start if the BCM handles the immobilizer or start authorization
Other communication codes may set alongside it

Common causes

Most likely first

Body control module was replaced with one running a different software/calibration version than the vehicle needsLikely
Interrupted or incomplete software update (reflash) of the moduleCommon
Wrong part fitted — module part number does not match this vehicle or trimCommon
Module installed but never programmed/configured with the vehicle's as-built dataLess often
Software corruption within the moduleLess often

How to diagnose & fix

Work through it in order

Scan all modules and confirm the code targets the body control module; note its software and calibration part numbers.
Verify the installed module is the correct part number for this VIN.
Reprogram/reflash the module to the correct current software with an OEM-capable scan tool.
Complete module configuration (write as-built/VIN data) after flashing.
If a used or aftermarket module cannot be matched, fit the correct part and program it. Clear codes and confirm all modules report compatible versions.

FAQ

Quick answers

Is it safe to drive with U0322?+

Often yes, but the BCM runs many electrical systems, so expect features like lighting, wipers, or locks to misbehave. On some vehicles it also controls start authorization, so a no-start is possible — get it corrected soon.

Can I just clear U0322?+

Clearing it won't help — the software versions still don't match, so the code returns. The module has to be flashed to the correct, compatible software.
