U0212 code meaning
Lost Communication With Steering Column Control Module
What U0212 means
U0212 means the steering column control module, which reads stalks and steering wheel buttons such as wipers, turn signals and cruise switches, is missing from the network. Ford's 2023 diesel OBD summary lets the engine computer set it once the SCCM's message has been absent for more than 5 s, while the 2014 Ford list carries it with no MIL flag. GM bulletin 20-NA-114 (CT4, CT5, Escalade, Tahoe, Yukon, Suburban, Corvette 2020–2021 with electric column lock N06) calls U0212 in IPC, BCM or gateway a wrong mapping and has it diagnosed as U0236. Stellantis note 9100447 (Pacifica, Voyager 2024–2025) wants BCM checks, switch and airbag plugs and wiper or turn signal tests before a new SCCM.
U0212 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.3 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0212
- Wipers, turn signals or steering wheel buttons inoperative
- Cruise control unavailable
- Code stored in several modules without any complaint
Common causes of U0212
- Most likelyFalse code mapping with electric column lock (GM N06, diagnose U0236)
- PossibleSwitch or airbag connectors at the column loose or corroded
- PossibleHarness chafed at the base of the steering column
- Less likelySteering column control module faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0212 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 12 | The exact fault in that area. |
What to do next
- Note U0212 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.
