2.3.1 Modes of Operation
The EUT is powered via a fused feed from the vehicle battery power distribution center and the feed is always
active.
2.3.1.1 Receive
The EUT has two modes of Receiver operation depending upon the vehicle status:
Receiver is periodically activated and deactivated (Polling mode) whenever the RTM is not awake and
the vehicle CAN serial bus is asleep.
o
Note: Polling operation requires RKE Fob ID’s to be learned and/or TPM functionality to be
enabled.
Receiver is continuously active whenever RTM is awake or vehicle CAN serial bus is awake.
2.3.1.2 Transmit
The EUT transmit operation is activated whenever a valid received RF data message contains a Vehicle status
request action code. TX mode is terminated when the message has been transmitted. RX mode will not be
active when the EUT TX mode is in operation.
Vehicle status request transmission from RKE Fob occurs either following a vehicle Remote Start or
Stop request or after a certain period of time expires following the receipt of a function pending status
request.
