To illustrate this,Figure 5 depicts a typical schematic representation of LS GMLAN network topology and connection to the DLC for a 2019 K1500 (New Model) pickup. Cause #2 The cause of condition 2 may be the SDGM X1 or X2 connector terminals being bent, backed out, or having loose terminal tension. The fairly recent introduction of modules having names such as "Serial Data Gateway Module" or, "Central Gateway Module" is simply for the purpose of cyber security. With a battery charger/maintainer connected to the vehicle, attach one side of a 194 bulb to circuit 5986 (at the suspect module) and the other side to a good ground (battery negative). Technical Document Number: #PIT5586G In response to a faulty fuel sensor control module, GM is recalling 13 of its 2009 models. The communication enables circuit wakes up the module for serial data bus communication. In the example used above and as has traditionally been the case, LS GM LAN diagnostics can at least initially be performed directly at DLC terminal # 1 to identify the type of fault affecting the bus. That's quite a "mouthful", so we can assume that Global "B" will be way that most technicians will refer to the new network architecture. \u0026nbsp;\u0026nbsp:Disclaimer:Due to factors beyond the control of The Flat Rate Mechanic, it cannot guarantee against unauthorized modifications of this information or improper use of this information.
