U0555Invalid Data Received From Remote Start Module
- Generic OBD-II code · Network
- How the car detects it
- A remote start module lets the engine run from a key fob or app for heating or cooling and must work around the immobilizer while doing so; it may be a factory part, a dealer accessory or an aftermarket box tied into the CAN network. GM lists the remote start module as its own node (Saab 9-5 2011: U0254). Subaru shows how a mismatch in the interface between gateway and its accessory Remote Engine Starter set U0254 on the 2020 Legacy/Outback without any effect on function, cured by revised modules (15-258-19R). Mercedes warns that aftermarket remote start and other CAN devices on Sprinter and Metris can cause communication faults and failed programming. U0555 means frames come in but are invalid; U0254 means none arrive. No bulletin names U0555. Remote start may fail or nothing is noticeable.
