U0131 on Chevrolet
Lost Communication with Power Steering Module
U0131 on Chevrolet vehicles indicates lost communication with power steering module. Au7o has documented this code across 2 Chevrolet models — most commonly on Corvette, Silverado 1500. 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 Chevrolet by Model
Chevrolet Corvette(1 issue)
- Electric Power Steering Gear Failure Causes Sudden Loss of Steering Assist (Recalls 19V086 and 25V175)2017
The electric power steering gear assembly on the 2017 C7 can fail without warning, dropping power assist while the car is being driven. Owners report the steering suddenly becoming very heavy, sometimes recovering only after the ignition is cycled. NHTSA logged six power-steering complaints for the 2017 model year. GM recalled the car twice for the same component: campaign 19V086000 (GM recall N182182760), with remedy beginning June 13, 2019, and again under campaign 25V175000 (GM recall N252497020), with owner notification beginning April 15, 2025. Both campaigns cover the same family of GM vehicles built around the Alpha/Y-body EPS gear, including the 2017 Camaro and Cadillac CTS/ATS. The loss of assist is most dangerous at low speed and during parking or tight maneuvers, where steering effort rises sharply.
Chevrolet Silverado 1500(1 issue)
- Sudden Loss of Electric Power Steering Assist / EPS Rack Failure (NHTSA Investigation)2014-2024
The Silverado 1500 uses a rack-mounted electric power steering (EPS) system, and owners across multiple model years report sudden, momentary loss of steering assist — usually at low speed — often with a 'Service Power Steering / Drive Carefully' message, a clicking or notchy feel, and warning lights. On the 2014-2015 trucks GM recalled vehicles for a software condition where assist could drop out and then return abruptly (reprogram of the steering control module). For 2020-2024 trucks, NHTSA's Office of Defects Investigation opened an investigation after a high volume of complaints of sudden power-steering failure; many of these resolve with a full steering gear (EPS rack) replacement rather than a software flash. Loss of assist sharply increases steering effort and crash risk, especially during parking-speed maneuvers.
