U0131 on Mitsubishi
Lost Communication with Power Steering Module
U0131 on Mitsubishi vehicles indicates lost communication with power steering module. Au7o has documented this code across 1 Mitsubishi model — most commonly on Eclipse Cross. This is a network communication code meaning the vehicle's computers have lost communication with the power steering control module over the data bus (CAN). Modern cars link control modules so they can share data, and this code sets when other modules stop receiving expected messages from the power steering unit. The most common result is loss or reduction of power-assisted steering, making the wheel feel heavy, along with a warning light. It generally points to a wiring/connector or power problem at the steering module, a bus fault, or a failed module rather than a mechanical steering issue.
Common Causes of U0131
- •Loss of power or ground to the power steering module
- •Open or shorted CAN bus wiring to the module
- •Corroded or loose connector at the steering module
- •Blown fuse feeding the power steering system
- •Failed power steering control module
- •Other module or wiring fault disrupting the data bus
- •Software/configuration mismatch after a repair

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.

What does U0131 mean on Mitsubishi?▼
U0131 stands for "Lost Communication with Power Steering Module." This is a network communication code meaning the vehicle's computers have lost communication with the power steering control module over the data bus (CAN). Modern cars link control modules so they can share data, and this code sets when other modules stop receiving expected messages from the power steering unit. The most common result is loss or reduction of power-assisted steering, making the wheel feel heavy, along with a warning light. It generally points to a wiring/connector or power problem at the steering module, a bus fault, or a failed module rather than a mechanical steering issue. On Mitsubishi specifically, this code is documented across 1 model.
What causes U0131 on Mitsubishi vehicles?▼
