Check DLC3

CHECK DLC3







The HV control ECU uses the ISO 15765-4 communication protocol. The terminal arrangement of the DLC3 complies with ISO 15031-03 and matches the ISO 15765-4 format.

NOTE: *: Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the power switch, other switches or doors.

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 power switch ON (IG) and operated the tester, there is a problem on the vehicle side or tester side.
- If communication is normal when the tester or scan tool is connected to another vehicle, inspect the DLC3 on the original vehicle.
- If communication is still not possible when the tester or scan tool is connected to another vehicle, the problem is probably in the tester or scan tool itself, so consult the Service Department listed in its instruction manual.
