Connect the cable of the intelligent tester to the DLC3, turned the ignition switch ON and attempt to use the intelligent tester. If the screen displays UNABLE TO CONNECT TO VEHICLE, a problem exists in the vehicle side or tester side.

• If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the original vehicle.

• If communication is still impossible when the tester is connected to another vehicle, the problem is probably in the tester itself. Consult the Service Department listed in the tester's manual.

(b) Check the battery voltage.

3. INSPECT BATTERY VOLTAGE (a) Inspect the battery voltage. Voltage: 11 to 14 V

If voltage is below 11 V, recharge the battery before proceeding.
