wiTECH VCI Pod Smart Cable and Fiat 500
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 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.
