VSM - Vehicle Security Module
It is mounted on the firewall, just above the transmission hump and behind the radio. It has 3 multi-connector plugs to it and must be scanned and reprogrammed by a dealer into a new one. You can't just swap them out.
would this part also cause the vehicle to not start if its going out?
I have an intermittent problem with my alarm / security system, causing the truck to not start.

Prior to 2002, the 99-01 did not have a VSM, it was called a GEM. I am not that familiar with the GEMs but I understand that they did much of the same functions as the VSMs now do. I believe that the GEM is located above or next to the under-dash fuse panel on the 99-01. It is possible that the (factory?) security system is tied into it and some owners have reported that a windshield water leak will drip on the GEM, due to its location and cause problems.
