Check DLC3

CHECK DLC3







The vehicle's ECU uses BEAN of ISO 9141-2 for communication.
The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 9141-2 format.

HINT: If the screen displays "UNABLE TO CONNECT TO VEHICLE" after you have connected the cable of the hand-held tester to the DLC3, turned the ignition switch to the ON position and used the hand-held tester, there is a problem on 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, so consult the Service Department listed in the tester's manual.
