Directed Electronics SR6000 manual Bypassing GM vehicle anti-theft systems Vats

bypassing GM vehicle anti-theft systems (VATS)

Vehicles with the GM VATS (Pass Key) systems have a resistor embedded in the ignition key. If the VATS decoder module does not measure the proper resistance when the vehicle is started, the starter and fuel pump may be disabled for up to ten minutes. An optional "VATS pack" of resistors is available (p/n 652T). One of the resistors in the pack will match the resistor in the key.

The VATS wires will be two very light-gauge wires coming out of the steering column. The colors of the wires vary, but they are often contained in orange tubing - either both will be white wires, or one wire will be purple/white and the other white/black. Determine the value of the resistor in the key. Then follow the diagram below to bypass VATS during remote start operation. If the H3/1 BLUE status output has been programmed for factory security re-arm, use the H3/2 BLUE/BLACK third ignition output to control the relay.

NOTE: When connecting to the VATS wires, it is not important which wire is cut.
