Lost Communication With Steering Effort Control Module
What it means
The steering effort control module changes steering assist with speed, making the wheel light when parking and firmer on the highway. This code sets when messages from this module stop reaching the network. Makers use this name in different ways: on some vehicles it refers to a variable-assist hydraulic valve control, on others it is tied to the electric power steering module.
Symptoms4
- Steering warning light or a steering system message.
- Heavier than normal steering at low speed and when parking.
- Very light steering at high speed on some systems.
- Sudden changes in steering effort while driving.
Possible causes6
- Blown module power fuse.
- Weak battery or low voltage while running.
- Corroded or loose module connector.
- Poor ground connection.
- Open or shorted CAN wiring to the module.
- Internal module failure.
How to diagnose5
- Use the service information to identify which module this code refers to on your vehicle and where it is.
- Read codes from all modules and check for U0131 or steering angle sensor codes.
- Try to connect to the module with a scan tool; if it does not respond, check its fuse, power and ground.
- Inspect the module connector for corrosion or loose pins.
- Check the CAN lines to the module and compare their resistance with the manufacturer specification.
How to fix5
- Replace the blown fuse and charge or replace the battery.
- Clean the connector and repair the ground point.
- Repair damaged network wiring.
- Replace the module if proven faulty, then program it as the manufacturer instructs.
- Clear the codes, test the steering at different speeds and confirm the code does not return.
Repair cost
In Saudi riyals; the highlighted part is the expected range for this fault.
The cost is low for a fuse, connector or battery, and rises when the module must be replaced and programmed.
Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions
Will the steering stop working with this code?
No, the steering still works, but it may be heavier when parking or lighter at high speed. Drive carefully and avoid sharp maneuvers until it is fixed.
How is it different from U0131?
U0131 refers to the power steering module itself, while this code refers to the module that controls how light the steering feels. On some vehicles they are one unit, so both codes appear together.
