Vehicle Theft Security System
NAME OF CODELeft Door Key Switch Failure
WHEN MONITORED
Any time battery voltage is above 10.0 volts and the BCM is awake.
SET CONDITION
The BCM senses a voltage that is lower than 4.9 volts on the left door key cylinder switch sense circuit for longer than 10 seconds.
THEORY OF OPERATION
The BCM sends a 5.0 volt reference circuit to the door key switch. Each switch when activated will lower the voltage signal from 5.0 volts down to 4.0 volts to disarm the VTSS or 2.0 volts to arm the system. The BCM will monitor the switch for a stuck condition (active for more than 10 seconds) and set this code.
POSSIBLE CAUSES
- Stuck switch.
- Left door key cylinder switch sense circuit shorted to ground
- Switch held in locker unlock position too long.
- Defective BCM.
