Check DLC3

CHECK DLC3







The vehicle's ECU uses the ISO 9141-2 communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 9142-2 format.






HINT:
- When troubleshooting the push-button function using the hand-held tester with the engine switch off, connect the hand-held tester to the vehicle and repeat turning any of the courtesy light switches on and off until communication between the tester and the vehicle begins (the interval between ON and OFF should be less than 1.5 sec.).
- Connect the cable of the hand-held tester to the DLC3, turn the engine switch on (IG) and attempt to use the hand-held tester. If the display informs that a communication error has occurred, there is a problem either with the vehicle or with the tester.
- If the communication is normal when the tester is connected to another vehicle, inspect the DLC3 on the original vehicle.
- 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's instruction manual.
