'''General Motors Local Area Network''' (GMLAN) is an application- and transport-layer protocol using [[controller area network]] for lower layer services.<ref>{{cite web |url=https://global.ihs.com/doc_detail.cfm?document_name=GMW3089 |title=GMW3089 |accessdate=2018-08-08 |quote=General Motors Local Area Network (GMLAN) Single Wire Controller Area Network (SWCAN) Physical and Data Link Layers Specification }}</ref> It was standardized as SAE J2411 for use in [[OBD-II]] vehicle networks.<ref>{{cite web |url=https://www.kvaser.com/can-protocol-tutorial/ |title=Controller Area Network (CAN BUS) Protocol {{!}} Free Course |publisher=Kvaser |access-date=2020-09-27}}</ref>

==Transport-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.<ref name="Hartman2004">{{cite book|author=Jeff Hartman|title=How to Tune and Modify Engine Management Systems|url=https://books.google.com/books?id=KZSbG-dVT3YC&pg=PA252|date=13 February 2004|publisher=Motorbooks|isbn=978-0-7603-1582-8|pages=252–|quote=GMW3110}}</ref> GM's Tech2 uses the CANdi (Controller Area Network diagnostic interface) adapter to communicate over GMLAN.

==Applications==
Some software applications that allow interfacing to GMLAN are Intrepid Control Systems, Inc.'s Vehicle Spy 3; [[Vector Informatik|Vector]]'s CANoe; Dearborn Group's Hercules, ETAS' ES-1222, ES590, ES715, and ES580; ScanTool.net's OBDLink MX; EControls by Enovation Controls' CANCapture; and GMLAN vehicle universal remote control GMRC for [[Android (operating system)|Android]] devices

Tesla uses J2411 (single-wire CAN over the Control Pilot) for their DC Supercharger (newer units are also capable of PLC over the control pilot) and AC Destination Charging.<ref>{{cite tech report |title=Review of Electric Vehicle Charger Cybersecurity Vulnerabilities, Potential Impacts, and Defenses |first1=Jay |last1=Johnson |first2=Timothy |last2=Berg |first3=Benjamin |last3=Anderson |first4=Brian |last4=Wright |publisher=Sandia National Laboratories |location=US |doi=10.3390/en15113931 |doi-access=free |date=2022-05-26}}</ref>
