- Generic OBD-II code · Network
- Can trigger limp mode
- How the car detects it
- U0150 is the last code of the gateway block and points at Gateway E. Gateways are central nodes that connect bus systems of different speed and type and forward only the messages each side needs. When E stops sending, the modules that expect its traffic log U0150, the way GM's U0100-U02FF procedure describes for any silent sender: a supervised periodic message is missing although supply voltage is in range. No manufacturer documents U0150 publicly; GM's U-code list ends its gateway entries at U0146. U0146 to U0149 refer to gateways A to D. Before suspecting the gateway, check power, ground and the bus lines to it; a code stored only in history after battery work needs no repair. MIL normally stays off.
