Code U240D GMC Description

The powertrain high-speed General Motors Local Area Network (GMLAN)serial data circuits are serial data buses used to communicate information between the devices. The powertrain high speed GMLAN serial data circuits also connect directly to the X84 Data Link Connector (DLC) for programming purposes.

The device setting the Diagnostic Trouble Code (DTC) has attempted to establish communications on the powertrain high-speed GMLAN serial data circuits more than 3 times.
