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 intelligent tester to the DLC3, turned the ignition switch to the ON position 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.
