| CHECK DLC3 |
The vehicle ECU uses the ISO 15765-4 for communication protocol. The terminal arrangement of the DLC3 complies with ISO 15031-3 and matches the ISO 15765-4 format.
Symbols (Terminal No.) Terminal Description Condition Specified Condition CG (4) - Body ground Chassis ground Always Below 1 Ω SG (5) - Body ground Signal ground Always Below 1 Ω BAT (16) - Body ground Battery positive Always 9 to 14 V CANH (6) - CANL (14) CAN bus line Engine switch off* 54 to 69 Ω CANH (6) - Battery positive HIGH-level CAN bus line Engine switch off* 6 kΩ or higher CANH (6) - CG (4) HIGH-level CAN bus line Engine switch off* 200 Ω or higher CANL (14) - Battery positive LOW-level CAN bus line Engine switch off* 6 kΩ or higher CANL (14) - CG (4) LOW-level CAN bus line Engine switch off* 200 Ω or higher - HINT:
- Connect the cable of the intelligent tester to the DLC3, turn the engine switch on (IG) and attempt to use the intelligent tester. If the screen displays a communication error message, a problem exists on either the vehicle side or the tester side.
If the communication is still impossible when the tester is connected to another vehicle, the problem is probably in the tester itself. Consult the Service Department listed in the tester instruction manual.- NOTICE:
- *: Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the engine switch, any other switches or the doors.
