security light
 

Well recently when i'm driving i've noticed that sometimes when i've been driving for about 10 minutes the SECURITY light comes on. It doesnt do it every time either. it seems to be driving fine. i searched about it and read that it sometimes is a problem with the starter or something.

yall have any ideas why it could be doing this

Thanks, Tyler

The body control module (BCM) will read an analog voltage form the Passlock sensor. Based on an internal reference, the BCM will determine if the measured voltage is in 1 of the following conditions:

• Open
• Shorted to ground
• A valid code
• A tamper code
There are 10 possible valid code combination. The BCM will only recognize the last learned valid code.
Conditions for Setting the DTC
• The ignition switch is ON.
• The BCM signal input is less than 0.4 volts for 1 second after turning the ignition switch to the CRANK position.
Action Taken When the DTC Sets
• The vehicle will not start if the fault occurs before you start the vehicle. The security telltale will flash for 10 minutes then turn ON steady.

************************************************** ************************************************** **********
***********• If the vehicle is running when the fault occurs, the BCM will be in the fail enable mode allowing the vehicle to start and run. The security telltale will be ON. *************************
************************************************** ************************************************** ********

Conditions for Clearing the DTC
• The DTC will clear once the ignition cycle has occurred without the fault recurring.
• The BCM history codes will clear once 100 concurrent ignition cycles occur without the fault recurring

What I read here tells me that you need to have your history codes read

what does that mean?
how do i have my history codes read?

well i still need an answer to that...
and one other thing i have no idea if this has anything to do with any of this. But just a few minutes ago i went out to start my car and it would crank. run for a second and cut off. Fuel filter problem maybe?
