DIAGNOSIS SYSTEM





1. CHECK DLC3
If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector.





HINT: If the display shows UNABLE TO CONNECT TO VEHICLE when you have connected the cable of the Techstream to the DLC3, turned the ignition switch to ON and operated the tester, a problem exists in either the vehicle or tester.
- If communication is normal when the tester is connected to another vehicle, inspect the DLC3 on the original vehicle.
- If communication is still impossible when the tester is connected to another vehicle, the problem is probably with the tester itself. Consult the Service Department listed in the tester's instruction manual.
