The BCM activates this circuit when the ignition key is in ACC, ON and START positions (there will be voltage present in the OFF position only for a short time until the BCM goes to sleep). Silverado, sierra hybrid. %PDF-1.6 % So, let's explore what is really happening, by considering how data bus communication diagnostics have been conducted for some time now. In other words, much like the famous elusive spy, the networks that exhibit these DTCs when faulted, are hidden behind the Serial Data Gateway Module and cannot be diagnosed from the DLC using conventional means such as DMM, DBDT or DSO. Through the "eyes" of the DBDT, we now have a different and more comprehensive list of our "healthy" LS LAN than with GDS 2, as shown in Figure 4. Consider for a moment that these were all modules on a healthy bus a few moments ago, but now have associated DTCs. Check if this part fits your vehicle. There are two known areas where circuit 5986 has been found to be open/shorted/high resistance: On short wheelbase utilities (Escalade, Tahoe and Yukon), the chassis harness cut/pinched/shorted between the body and spare tire crossmember see latest version of PIT5556 for more details.
