Thank-you Martin. 2008-2013 GM part # 84442220 - Battery Energy Control Module. 12-10201 ABS Control Module 2003-2005 Escalade ESV Suburban 1500 Tahoe Yukon Yukon XL 1500. . In response to a faulty fuel sensor control module, GM is recalling 13 of its 2009 models. 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. The BCM is able to communicate on both LS and HS GM LAN and thus is still able to report an issue. Perhaps we should first qualify whether those red circles are identifying non-communicating modules, or whether those modules are not fitted to this particular vehicle. HX v HE Qa)H 4 The communication enables circuit wakes up the module for serial data bus communication. 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).
