DTC B3033 Security System Indicates Tamper
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.
|I am very upset that I have to spend 5-7 hundreds dollars on an anti-theft thing that went
bad. THAT SHOULD NOT BE MY PROBLEM THAT'S WHY PEOPLE GO OUT PUT ALARM
SYSTEMS IN THERE CARS. ITS THE HOLIDAYS WITH THIS ECONOMY LIVING PAY
CHECK TO PAY CHECK THIS REALLY SUCKS!!!!!!
