Theft / Security Light
The security system on todays cars and trucks prevents the vehicle from
being stolen. There are many variations of the system going back to the
early 1990's.
This warning could be on when the engine is running, indicating a fault has
been detected in the system. If left unrepaired, there is a good posiblity that
the car will eventually not start.
There are several different possibilities for the cause of the warning,
depending on the make / model / year of the vehicle. Anything from a bad
ignition cylinder wire, to a bad cylinder to a dad Body Control Module (BCM).
After market (non-factory) alarm and remote start systems can cause havoc
with the factory theft system, causing this warning light, or a no start.
