Event Notification Signal
The event notification feature provides other vehicle subsystems with information pertaining to SRS deployment or fuel cutoff status. When an impact occurs which exceeds a pre-determined threshold, the RCM sends a signal on a dedicated circuit to the BCM. On Hybrid Electric Vehicles (HEVs) or Plug-in Hybrid Electric Vehicles (PHEVs), the BECM also receives this signal.
For all vehicles, when the BCM receives the event notification signal input, it initiates fuel cutoff to disable the fuel system.
For Hybrid Electric Vehicles (HEVs) and Plug-in Hybrid Electric Vehicles (PHEVs), the BECM commands the high voltage contactors open when the event notification signal is received from the RCM.
After the fuel system is disabled, the vehicle can be re-started after carrying out the following steps:
- Turn the ignition OFF.
- Turn the ignition ON.
- Turn the ignition OFF.
- Turn the ignition ON.
