1. Connect the intelligent tester to the can vim. Then connect the can vim to the dlc3.
2. Run the vehicle until the transmission fluid temperature has reached 50 to 80°c (122 to 176°f).
3. Allow the engine to idle with the air conditioning off.
4. Chock all 4 wheels.
5. Set the parking brake and keep the brake pedal depressed firmly with your left foot.
