Fuel Pump Shut-off Feature
WARNING: This page is about a different variant/trim than selected.
NOTE:
Refer to the appropriate service information (in Intelligent Access with Push Button Start article(s)
)
to review the procedures for achieving the various ignition states (ignition OFF, ignition in ACCESSORY, ignition ON and ignition START) on vehicles with this feature.
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.
When the BCM receives a crash signal input from the RCM, the BCM initiates fuel cutoff by removing the ground signal from the Fuel Pump Relay and also sends a signal to the PCM on a dedicated circuit, disabling the fuel system.
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 to START (on vehicles with push button start, press the start/stop button while the brake pedal is pressed).
- Turn the ignition OFF.
- Turn the ignition ON.
