An industry change in protocol from OBD II to Controller Area Network (CAN) has begun. In order to perform diagnostics on a vehicle that uses the CAN interface, you will need the Tech 2 Flash and a CAN diagnostic interface module.
The CANdi module connects between the Tech 2 Flash’s Diagnostic Link Cable and the OBD adapter. Once the CANdi module is connected, it can be used on all GM vehicle applications, even those vehicles using other platforms such as OBD I and II. As of this printing, the following GM vehicles.
utilize the CAN interface:
- 2003 Saturn ION
- 2004 Buick Rendezvous (3.6L)
- 2004 Cadillac SRX
- 2004 Cadillac XLR
- 2004 Cadillac CTS (3.6L)
- 2004 Chevy Malibu (Body/chassis only)
- Other GM vehicles may also adopt the CAN protocol in the future.
