Inspect the DLC3

Inspect the DLC3







The vehicle's ECM uses V.P.W. (Variable Pulse Width) for communication to comply with SAE J1850. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the V.P.W. format.

HINT:
If your display shows "UNABLE TO CONNECT TO VEHICLE" when you have connected the cable of the hand-held tester or OBD II scan tool to the DLC3, turned the ignition switch ON and operated the scan tool, there is a problem on the vehicle side or tool side.
- If the communication is normal when the tool is connected to another vehicle, inspect DLC3 on the original vehicle.
- If the communication is still not possible when the tool is connected to another vehicle, the problem is probably in the tool itself, so consult the Service Department listed in the tool's instruction manual.
