GMLAN

From Wikipedia, the free encyclopedia

GMLAN is an application- and transport-layer protocol using CAN for lower layer services. Transport-layer services include the transmission of multi-CAN-frame messages based on the ISO 15765-2 multi-frame messaging scheme. It was developed and is used primarily by General Motors for in-vehicle communication and diagnostics.

Some software applications that allow interfacing to GMLAN are Intrepid Control Systems, Inc.'s Vehicle Spy 3, Vector's CANoe, Dearborn Group's Hercules, and ETAS' products ES-1222, ES590, ES715, and ES580.
