Most Reported On
U0126 is an OBD-II diagnostic trouble code meaning “Lost Communication With Steering Angle Sensor Module.” Sets when a module loses data-bus communication with the Steering Angle Sensor Module, which provides steering position to the stability system, and no longer receives its expected messages. This code is most commonly reported on 2018-2021 Mitsubishi Eclipse Cross.
Common Causes
Diagnostic Tools
This is a network/communication code. A basic engine-code reader will not show it — you need a scanner that reads all modules. These read U0126.
One caveat that applies to every scanner: only powertrain codes are standardised across manufacturers. Body, chassis and network coverage is "enhanced" diagnostics, and how deep it goes varies by make and model year — check your specific vehicle against the tool's coverage list before buying.

What you can do yourself, and what needs a shop
Reading the code, clearing it, and watching whether it returns is a driveway job with the right scanner. These steps are not:
- Module programming or software updates — needs the manufacturer software or a J2534 pass-through with a paid subscription.
- Replacing a control module — most are VIN-programmed and immobilizer-registered, so a new one does nothing until it is coded to your car.
- Airbag/SRS component work — a stored fault can deploy a live device.
If the vehicle is still under warranty, check for an open recall or technical service bulletin before buying anything — the repair may already be covered.
