Installer provided equipment: a USB/CAN interface cable (Toro DIAG cable) Part No. 115-1944

1. Park the machine on the grass at a level location.

2. Shut off the engine and engage the parking brake.

1. If the Toro Diag application is running on the laptop computer, close the Toro Diag application.

   Important: Do not begin the calibration process if the Toro Diag application is running on the laptop computer.

2. Plug the USB/CAN interface cable into a USB port of the laptop computer.

3. At the machine, rotate the key to the ON position.

4. Open the Plus+1 program.

5. Remove the cap from the 3-socket connector of the kit wire harness CAN port labeled DUPLICATE DIAG CONNECTOR, and plug the 3-pin connector USB/CAN interface cable into the 3-socket connector.
