U0130
UniversalLost Communication With Steering Effort Control Module
A control module has detected that it is not receiving expected communications from the steering effort control module over the vehicle network. That module may manage or adjust steering assistance, depending on the vehicle. Steering may feel heavier or behave differently, warning lights may appear, or there may be no noticeable symptom if the communication loss was brief. This code alone does not prove that the steering module has failed.
⚠️ Before You Begin (Safety First)
If steering suddenly becomes very heavy, unpredictable, or difficult to control, pull over safely and arrange professional assistance rather than continuing to drive. If steering feels normal, have the fault diagnosed promptly and watch for changes.
Common Symptoms
- Steering may require more effort if steering assistance or effort adjustment is reduced or unavailable.
- A steering warning light or other warning message may appear.
- Steering response or feel may change if the control module cannot share information with other vehicle systems.
- There may be no noticeable symptoms if communication was interrupted only briefly or the vehicle's systems continued operating normally.
- Other warning lights or stored communication codes may occur if the network or its power supply is affected.
Common Causes
- Low or unstable vehicle battery voltage may interrupt module operation or network communication.
- A loose, damaged, corroded, or poorly connected power or ground connection may prevent the steering effort control module from operating reliably.
- Damaged wiring or a poor connection in the vehicle communication network may prevent expected messages from reaching the module.
- A fuse or power-supply circuit problem may interrupt power to the module.
- A fault in the steering effort control module or another network-connected module may disrupt communication.
Diagnostic Steps
- Note any steering changes and warning messages. If steering is difficult or unpredictable, stop driving when it is safe to do so and arrange assistance.
- Check whether the battery is weak, recently discharged, or associated with other electrical problems. A qualified battery test can help identify unstable supply voltage.
- With the vehicle safely parked and switched off, visually check accessible battery terminals and wiring for looseness, corrosion, or damage. Do not disconnect steering or network components without vehicle-specific instructions.
- If a suitable scan tool is available, record codes from all modules before clearing anything. Related codes can help show whether the issue is isolated or affects the wider network.
- If the code returns or steering symptoms are present, have a technician test module power, grounds, connectors, and network communication using service information for the exact vehicle.
When to Call a Professional
A technician can scan all vehicle modules for related communication and voltage codes, check module power and grounds, and inspect network wiring and connectors using vehicle-specific service information. If those checks are satisfactory, further network testing can help distinguish a wiring fault from a control-module problem. Do not replace the module based on this code alone.

Commonly Asked Questions
Does U0130 prove that the steering effort control module is bad?
No. It indicates lost communication, which can result from power, ground, wiring, connector, network, or module problems. Testing is needed to identify the cause.
Can I drive with U0130?
It depends on how the steering behaves. If steering becomes very heavy or unpredictable, stop safely and arrange assistance. If it feels normal, seek prompt diagnosis and do not ignore new symptoms.
Why might there be no steering symptoms?
The communication loss may have been brief, or other vehicle systems may allow normal-feeling steering to continue. The stored code still warrants checking, especially if it returns.
What is the first useful diagnostic distinction?
A scan of all modules can show whether U0130 is isolated or accompanied by other communication or voltage-related codes. That helps guide checks of power, grounds, network wiring, and the module.
