What Does U0212 Mean?
The control module storing this code has lost communication with the steering column control module over the vehicle's network bus. This module typically manages features like tilt/telescoping adjustments, steering wheel heating, and electric power steering controls.
Common Causes
35%
Faulty or corroded wiring/connectors between steering column module and network bus
30%
Failed steering column control module internal circuitry or communication chip
20%
CAN bus network fault affecting multiple modules or bus termination resistor failure
10%
Low voltage or power supply issue to steering column control module
5%
Software corruption or module requiring reprogramming after update
Diagnostic Steps
1
Step 1: Verify battery voltage is above 12.4V and inspect all fuses related to steering column module
2
Step 2: Inspect steering column module connector for corrosion, bent pins, or damage; wiggle test harness while monitoring live data
3
Step 3: Using scan tool, attempt to communicate directly with steering column module to determine if module is completely dead or intermittently responsive
4
Step 4: Check CAN bus voltage at steering column module connector (should see 2.5V on CAN High and CAN Low with ~0V difference at rest, fluctuating during communication)
5
Step 5: If wiring and power are good but no communication exists, replace steering column control module and reprogram/configure as needed
Estimated Repair Cost
$150 - $800
Parts + labor, varies by vehicle and location
The control module storing this code has lost communication with the steering column control module over the vehicle's network bus. This module typically manages features like tilt/telescoping adjustments, steering wheel heating, and electric power steering controls.
The most common cause of U0212 (Lost Communication With Steering Column Control Module) is: Faulty or corroded wiring/connectors between steering column module and network bus
Typical repair costs for U0212 range from $150 to $800, depending on the vehicle, location, and whether you do it yourself or go to a shop.
May affect power steering assist, adjustable steering column functions, and steering wheel controls. Vehicle may be safe to drive if basic steering function remains, but power assist or stability control features may be compromised.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to U0212 to identify the root cause.
