The table describes the type of signals used to communicate the RDU and AAN signals to the TeleAid control unit:
^
If the vehicle supports a discrete signal for AAN, a 12V signal to pin 32 on the TeleAid control unit will trigger a call for an alarm notification.
^
If the vehicle supports a discrete signal for RDU, a 0V signal to pin 41 on the TeleAid control unit will trigger a call for a remote door unlock
request.
Some models support CAN messages to the TeleAid control unit for both RDU and AAN.
