U0131 on Saturn
Lost Communication with Power Steering Module
U0131 on Saturn vehicles indicates lost communication with power steering module. Au7o has documented this code across 1 Saturn model — most commonly on Ion. 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

What does U0131 mean on Saturn?▼
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 Saturn specifically, this code is documented across 1 model.
