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.
