What Does U0131 Mean?
Communication has been lost with the Power Steering Control Module on the vehicle data network. This affects electric or electronically-controlled hydraulic power steering systems and prevents proper steering assist control.
Safety Warning
Loss of power steering assist can make the vehicle extremely difficult to steer, especially at low speeds or during parking maneuvers. This significantly increases accident risk. Avoid driving if possible; if necessary, drive slowly and avoid tight turns.
Common Causes
35%
Failed power steering control module or internal fault
30%
Corroded or damaged module connector or wiring harness
20%
CAN bus network circuit fault or open/short condition
10%
Loss of power or poor ground connection to steering module
5%
Module software corruption or calibration loss
Diagnostic Steps
1
Step 1: Check power steering module fuses and verify battery voltage at module connector
2
Step 2: Inspect module ground connections for corrosion or looseness
3
Step 3: Test CAN bus signals at power steering module using oscilloscope or multimeter
4
Step 4: Verify physical condition of module connector and pins for damage or corrosion
5
Step 5: Attempt module communication through scan tool and perform steering system functional tests
