OBD-II trouble code
U0212: Lost Communication With Steering Column Control Module
A module has stopped receiving messages from the steering column control module over the data network. This module handles steering-column functions like the clockspring, wheel controls, and often the steering-angle input, so features tied to it can be affected.

What does U0212 mean?
U0212 is a lost-communication network code: a receiving module has stopped getting expected messages from the steering column control module. This module manages steering-column-mounted functions — often the clockspring circuit for the horn and steering-wheel controls, turn-signal/wiper stalk inputs, tilt/telescope on some vehicles, and frequently the steering-angle sensor data used by stability control. When it drops off the communication bus, the network loses those inputs and stores U0212. Unlike an 'invalid data' fault where the module is still transmitting bad values, a lost-communication code means the module has effectively gone silent.
The steering itself remains mechanical/electric-assisted and the car drives, but features that depend on the module — steering-wheel buttons, horn, cruise/audio controls, and stability-control functions that use steering angle — can misbehave or drop out, and warning lights (airbag/SRS, stability, or a general warning) may appear. Common causes are power or ground loss to the module, damaged or corroded wiring and connectors (the clockspring and column harness flex constantly), a connector disturbed during airbag/clockspring or column service, an internally failed module, or a wider bus fault. Diagnosis confirms the module's power, ground, and network connection before replacement.
Common causes
- Loss of power or ground to the steering column control module
- Damaged or corroded wiring/connectors in the column harness
- Clockspring or column-harness wear from constant flexing
- Connector disturbed during airbag/clockspring or column service
- Internally failed steering column control module
- Blown fuse or a wider communication (bus) fault
Symptoms
- Steering-wheel controls, horn, or cruise/audio buttons not working
- Airbag/SRS, stability-control, or general warning lights on
- Stability/traction features affected if steering-angle data is lost
- Companion restraints or network codes stored alongside U0212
- Vehicle otherwise drives, with steering assist retained
Diagnostic steps
- 1.Scan all modules and record every code; note companion network or SRS codes suggesting a shared cause.
- 2.Locate the steering column control module and verify its power and ground feeds.
- 3.Inspect the column harness, connectors, and clockspring wiring for damage and corrosion.
- 4.Confirm whether the module or clockspring was recently serviced and reseat connectors as needed.
- 5.Use a scan tool to see whether the module responds on the network.
- 6.If power, ground, and wiring are good but the module stays offline, replace/program it per procedure — some vehicles require a steering-angle relearn afterward.
Repair cost
$100 – $900
Wiring, connector, or clockspring repairs are often $100-$450. A failed steering column control module with programming (and any steering-angle relearn) is the costlier case. Confirm power, ground, and the column wiring before replacing the module.

DIY vs shop
This is an advanced DIY job. It typically requires specialty tools, scan-tool access, lifting equipment, or careful sequencing to avoid causing new failures. Plan for extended downtime and have a backup vehicle. Most owners are better served by a shop that has done this repair before.
