HINT:
1 2 3 4 5 6 7 8 The vehicle's ECM uses ISO 9141-2 for communication. The
9 10 11 12 13 14 15 16 terminal arrangement of DLC3 complies with SAE J1962 and
matches the ISO 9141-2 format.

Terminal No. Condition Specified Condition
7 (Bus + line) - 5 (Signal ground) During communication Pulse generation
4 (Chassis ground) - Body ground Constant Below 1
5 (Signal ground) - Body ground Constant Below 1
16 (B+) - Body ground Constant 9 to 14 V
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 ON and used the hand-held tester, there is a prob-
lem on the vehicle side or tester side.
S If communication is normal when the tester is connected to another vehicle, inspect the DLC3 of the
original vehicle.
S 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.
