Check the DLC3

CHECK DLC3







The battery ECU uses the ISO 15765-4. The terminal arrangement of the DLC3 complies with ISO 15031-3 and matches the ISO 15765-4 format.

HINT: *: Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the ignition 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: Connect the cable of the intelligent tester or the OBD II scan tool to the DLC3, turn the power switch ON (IG) and attempt to use the tester. If the display indicates UNABLE TO CONNECT TO VEHICLE has occurred, there is a problem either with the vehicle or with the tester.
- 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.
