Since GM uses Snap On Business Solutions for the Electronic Parts Catalog, I would expect some form of relationship might be developed for the scan tool, but perhaps that is wishful thinking. A fairly extensive list of the affected modules is now displayed in Figure 7. So, let's take a look at how a healthy LS LAN appears on this vehicle with a SDGM in Figure 1. below There's green check marks for modules that are communicating and red circles with a line through identifying modules with no communication. container.style.maxWidth = container.style.minWidth + 'px'; The air bag module or the inflatable restraint sensing and diagnostic module (SDM) as they call it is under the left front seat.

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. However, as with some GM vehicles such as Cadillac XT4 and the 2019 new model pickup trucks that are Global "A" utilizing Generation 3 Serial Data Gateway Modules (SDGM), direct access to the primary HS GMLAN via the DLC is prohibited. Repair any opens/high resistance/shorts in the circuit. 22 0 obj

Stores collision data Note: The 2020 Chevrolet Bolt that is the subject in Figure 1 above is still a Global "A" vehicle, as easily identifiable at the DLC by the presence of Low Speed GMLAN (LS GMLAN) at terminal pin 1 as identified in Figure 2. 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). If removing the power feed fuse does not correct the condition, check and repair damaged, loose, or backed out X1 or X2 terminal connectors. The magazine automotive repair shop owners and technicians read first to learn about the latest tools and equipment in the automotive aftermarket that can increase productivity in the shop and maximize billable hours.
