Action Taken When the DTC Sets

WARNING: This page is about a different car, the 2004 Pontiac Grand Prix. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: If the BCM is unable to measure the ignition key transponder value for 30 consecutive seconds, after the vehicle has started, the BCM will enter a fail enable state. The BCM sends a message via the serial data circuit to the driver information center (DIC) to display the Service Theft - VTD Fail Enable message. The vehicle will not stall or stop running. If the BCM is in a fail enable state when the ignition is turned to OFF, it will remain fail enabled until the next time the vehicle is started. If the BCM is fail enabled, the vehicle theft deterrent (VTD) system is NOT active and the vehicle will start. The BCM WILL send its enable password even if a transponder value is not received. The BCM will remain fail enabled until the module measures a valid key transponder value for 5 consecutive ignition cycles then the BCM will exit the fail enable state.
