U0151 on Jeep
Lost Communication With Restraints Control Module
U0151 on Jeep vehicles indicates lost communication with restraints control module. Au7o has documented this code across 1 Jeep model — most commonly on Grand Cherokee. This network (U) code means other modules have lost communication with the restraints control module (the airbag/SRS computer) over the data bus. Because the restraints control module manages airbag and seatbelt pretensioner deployment, a communication loss can mean these safety systems are unavailable and the airbag warning light is typically on. The cause is usually power, ground, wiring, or connector related, though the module itself can fail. This is safety-critical and should be diagnosed promptly. Typical repair costs on Jeep range from $150 to $1,200, depending on the specific model and root cause.
Common Causes of U0151
- •Loss of power or ground to the restraints control module
- •Blown fuse feeding the module
- •Wiring or connector fault on the bus circuit
- •Corrosion at module connectors (often under-seat moisture)
- •Faulty restraints control module
- •Bus communication wiring damage

- Second-Row Seat Side Airbag Connector/Occupant Restraint Fault Warnings2022-2024
Owners of WL-generation Grand Cherokee models have reported persistent airbag warning lights and restraint system messages tied to seat wiring/connectors, especially around second-row or seat-mounted side airbag circuits. FCA also issued safety actions/TSB guidance on certain restraint-related faults in this generation. The practical problem is that the SRS may be disabled or operate improperly until the connector, harness, or module issue is corrected.
