U0126 on Mitsubishi
Lost Communication With Steering Angle Sensor Module
U0126 on Mitsubishi vehicles indicates lost communication with steering angle sensor module. Au7o has documented this code across 1 Mitsubishi model — most commonly on Eclipse Cross. 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.
Common Causes of U0126
- •Open or shorted bus wiring to the steering angle sensor module
- •Corroded or loose connector (often in the clockspring circuit)
- •Blown fuse / lost power or ground
- •Low battery voltage
- •Failed steering angle sensor module
U0126 on Mitsubishi by Model
Mitsubishi Eclipse Cross(1 issue)
- Forward Collision Mitigation Phantom Braking and FCM-ECU Software Defect2018-2021
Early Eclipse Cross models with Forward Collision Mitigation brake hard for objects that are not there. This is not just owner perception — NHTSA recall 18V620000 covers 2018-2019 Mitsubishi vehicles whose FCM-ECU software applies braking for longer than needed even after a pedestrian is no longer detected, with the stated consequence that drivers brake harder in response and increase rear-end collision risk. Companion recall 18V621000 covers a hydraulic unit ECU software defect that may prevent automatic emergency braking, ABS, electronic stability control and Brake Auto Hold from working properly. Owner complaints go beyond the recall scope: filings describe adaptive cruise control triggering FCM braking when cresting hills with nothing ahead, and repeated multi-warning-light events with hard braking recurring several times a year despite dealer repairs. The camera-and-radar fusion is sensitive to road crown, overhead signs and reflective surfaces, and the system's brake authority is high enough that a false trigger at highway speed is genuinely hazardous.
