Fiat 500 Vehicle Architecture

 
  • The first Fiat vehicle being sold in Chrysler, Jeep, and Dodge dealerships is the Fiat 500 (2012MY FF). 
  • The Fiat 500 does not contain a FCMCGW or a TIPMCGW central gateway, and thus does not contain a Diagnostic CAN-C bus. 
  • It features a CAN-C bus and a CAN-B bus, both of which are connected directly to the 16-pin J1962 diagnostic connector as follows:
 
CAN-C                   pins 6 and 14                      high-speed CAN
CAN-B                   pins 1 and 9                        low-speed CAN
 
  • A sample topology diagram from a Fiat 500 vehicle is below.


 

wiTECH VCI Pod Smart Cable

 
  • The wiTECH VCI Pod cannot support the Fiat 500 vehicle architecture when the standard vehicle cable is used. 
    • The wiTECH VCI Pod contains two high-speed CAN transceivers. 
    • It does not contain a low-speed CAN transceiver. 
    • When the standard vehicle cable is used, wiTECH VCI Pod can only support high-speed CAN communication on J1962 diagnostic connector pins 6/14 and pins 3/11. 
  • In order to support the low-speed CAN bus that is present at the J1962 diagnostic connector on the Fiat 500, the wiTECH VCI Pod Smart Cable must be used. 
    • The wiTECH VCI Pod Smart Cable contains a low-speed CAN transceiver that provides the wiTECH VCI Pod the ability to support both the CAN-C and the CAN-B buses.
 
The wiTECH VCI Pod Smart Cable may be ordered through the wiTECH Portal:
