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.
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 tub-
ing - 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 engine start operation. If the BLUE
status output from the relay satellite has been programmed for factory security
re-arm, then use the (H3/5) BLUE/WHITE 2
nd
status output from the control
module to control the relay.
Note: When connecting to the VATS wires, it is not important which wire is
cut.
