Steering Effort Control Module Software Mismatch
The U0319 code indicates that the Steering Effort Control Module (SECM), typically associated with electric or electro-hydraulic power steering systems, has incompatible software with the vehicle. This network communication code is triggered when the Engine Control Module (ECM) or Body Control Module (BCM) detects that the steering module's software version, calibration, or part number does not match the expected configuration. This often occurs after module replacement without proper programming, incomplete software updates, or installation of components from a different model or year.
1. Commonly Affected Makes
This is a generic OBD2 code, potentially applicable to any manufacturer using this diagnostic standard.
2. Most Common Causes
- Replaced power steering module without programming or calibration
- Incomplete or failed vehicle software update
- Installation of a steering module from a different vehicle, model, or year
- Data corruption in the steering effort control module
- Flash memory failure in the steering module
- ECM or BCM replacement without reprogramming associated modules
- CAN network communication interference during system startup
3. Symptoms You Will Notice
- Steering warning light illuminated
- Increased steering effort or loss of power assist
- Vehicle may enter limp mode or reduced power steering assist
4. Step-by-Step Diagnosis
Scan the vehicle for all stored codes and freeze frame data
Verify the steering module part number and software version match vehicle specifications
Check for any recent module replacements or software updates
Inspect CAN bus wiring for damage or interference
Attempt to reprogram the steering module with correct software
If reprogramming fails, replace the steering module and program it correctly
5. Frequently Asked Questions
Is it safe to drive?▼
No, driving with this code is not recommended as it can lead to loss of power steering assist, making the vehicle difficult to control, especially at low speeds.
How much does it cost to fix?▼
Repair costs typically range from $200 to $800, depending on whether reprogramming alone is sufficient or if module replacement is needed.
