Initial Condition To Activate The System
The operation of the vehicle security system is controlled by the doors, hood and trunk (for Roadster).
To activate the vehicle security system, BCM must receive signals indicating the doors, hood and trunk (for Roadster) are closed and the doors are locked by key or key fob.
When a door is open, BCM terminals 12, 5 receives a ground signal from each door switch.
When driver side door is unlocked by power window main switch (door lock and unlock switch), BCM terminal 22 receives a signal from terminal 12 of power window main switch.
When passenger side door is unlocked by power window sub-switch (door lock and unlock switch), BCM terminal 22 receives a signal from terminal 16 of power window sub-switch.
When the hood is open, IPDM E/R receives a ground signal
- To IPDM E/R terminal 56
- Through hood switch terminals 1 and 2, and
- Through body grounds E17, E43 and F152.
The IPDM E/R then sends a signal to the BCM via CAN communication line.
