U0131 on Jeep
Lost Communication with Power Steering Module
U0131 on Jeep vehicles indicates lost communication with power steering module. Au7o has documented this code across 1 Jeep model — most commonly on Grand Wagoneer. 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
U0131 on Jeep by Model
Jeep Grand Wagoneer(1 issue)
- Electric Power Steering Rack Failure and Assist Loss2022-2024
The Grand Wagoneer's electric power steering (EPS) rack-and-pinion assembly experiences premature failure, manifesting as sudden loss of power steering assist, wandering on the highway, or excessive steering effort. The EPS motor or internal torque sensor fails, triggering a steering warning light. Given the Grand Wagoneer's 6,000+ lb curb weight, loss of power steering assist makes the vehicle extremely difficult to control, especially at low speeds. Stellantis issued recall 23V-635 for certain VINs related to steering rack fastener torque, but the EPS motor failure is a separate concern.
