OPERATION
The hose module is activated from nozzle movement and change in orientation. As the nozzle is
inserted into the vehicle’s filler neck, the hose module will ‘prompt’ the VIT/Canceiver for its fueling
data via electromagnetic link. Upon receiving the ‘prompt’, the VIT/Canceiver will respond with
requested fueling data. Fueling data is analyzed by the module and relayed to the FCT via radio link.
After analyzing and approving data from the module, the FCT will enable the appropriate dispenser.

After analyzing and approving data from the module, the FCT will enable the appropriate dispenser.
As long as the hose module is in the fueling orientation, any movement perceived by the module
will cause the module to check if the VIT/Canceiver is still within range of the electromagnetic link.
When the module can no longer detect the VIT/Canceiver, a ‘Loss Of Signal’ (LOS) message is sent to
the FCT, and fuel is automatically shut off. If the nozzle is reinserted back in the filler neck and the
hose module detects the same VIT/Canceiver, fueling can continue. If a different VIT/Canceiver is
detected or the nozzle is returned to its holster, the original transaction closes out and another transaction
will be initiated.

To maximize life of hose module operation, always return the nozzle to the dispenser holster
after use. The module senses when it is not in a fueling position and places itself in a low-power mode to
conserve battery life. Therefore, if proper installation techniques were used, hose modules should
always orient in the normal upright position after fueling. In order to conserve power while
transporting hose modules, use the Hose Module Setup program on the Palmtop Programmer to lock the
module into its ‘sleep’ state by selecting <L> (lock hose module off) from the main menu.
