Remote Vehicle Start Circuit Description/Active
The BCM receives a signal from the keyless entry transmitter indicating a remote vehicle start request. The BCM and DMCM use the following inputs to verify the system is ready to enable a remote vehicle start event:
- Vehicle is not in valet mode
- Vehicle is in park
- Keyless entry transmitter is not in the vehicle
- The hood is closed
- The hazard switch is OFF
- Vehicle power mode is OFF
- The malfunction indicator lamp (MIL) is not commanded ON by the DMCM
- Remote start timer does not equal 0 (the 30 minute maximum time has not been used)
When the BCM determines all conditions meet those required for a remote vehicle start event, a message is sent via serial data to the DMCM.
If any conditions prevent a remote start or cause a remote start operation to be cancelled there is a record of the cause in the scan tool.
