The interface is used to translate the vehicle ECM diagnostic signals to a form that the Tuning Mode software can operate with.
CAUTION: Do not under any circumstances directly connect the vehicle to a PC without using the interface. This may permanently damage the vehicle’s ECM or the PC, and Tuning Mode will not function.
To connect the interface from the vehicle to the PC or laptop computer, follow these steps:
1.Refer to your vehicle’s manuals for the location and access method for the diagnostic data test connector.
2.Connect the vehicle cable (with the large plastic 4-pin connector) to the vehicle diagnostic connector, and snap it in place.
3.Connect the other end of the vehicle cable to the mating connector on the interface module. Secure the connector with the locking screws.
4.Attach the RS-232 extension cable to the other interface connector and secure the connector locking screws.
5.Attach the other end of the RS-232 extension cable to the PC or laptop serial port connector.
