Toyota RAV4 (XA40) 2013-2018 Service Manual: Diagnosis system
- Description
- Data of the system can be read through the data
link connector 3 (dlc3) of the vehicle.
Therefore, when the system seems to be malfunctioning, use the intelligent tester to check for a malfunction and repair it.
- Check dlc3
- The vehicle's ecm uses iso 15765-4 communication protocol. The terminal arrangement of the dlc3 complies with sae j1962 and matches the iso 15765-4 format.
Hint:
Connect the cable of the intelligent tester to the dlc3, turn the ignition switch on and attempt to use the tester. If the display indicates that a communication error has occurred, there is a problem either with the vehicle or with the tester.
- If communication is normal when the tester is connected to another vehicle, inspect the dlc3 of the original vehicle.
- If communication is still not possible when the tester is connected to another vehicle, the problem may be in the tester itself. Consult the service department listed in the tester's instruction manual.
