5.3.3 Identifying FOBS within LF Range

Identify the available fobs by sending out a broadcast, which returns the Fob# in the selected fob field. Perform the following steps to identify the available fobs within the LF range:

  1. If not done already, follow the procedure detailed in CARS Kit PC Evaluation Utility.
  2. In the System Configuration window, choose Broadcast from the “Selected Fob” drop-down list (see Figure 5-5).
  3. Click the Fob ID button to send the broadcast request. The available fobs respond with their fob IDs and their Fob# assignments. The “Fob Vehicle ID” field displays the returned vehicle ID.
  4. Click the S/W Ver button to send the software version request to the fob. The “S/W Ver” field displays the returned software version number.

    Note:
    • To use the broadcast function, it is recommended that only one fob be within range, and it must have a battery inserted in the battery socket.
    • Fobs that are not paired with the current system or that have a different vehicle ID, can also be identified as within range. If the located fob is paired with the system, the selected fob index changes to the location in the system where the fob is believed to be stored. It is recommended that the fob ID be verified by checking it against the list of learned fobs.
