Toyota RAV4 (XA40) 2013-2018 Service Manual: Diagnosis system
- Description
- Sliding roof system data and diagnostic trouble codes (dtcs) can be read through the vehicle's data link connector 3 (dlc3). When the system seems to be malfunctioning, use the intelligent tester to check for malfunctions and perform repairs.
- Check dlc3
The vehicle uses the iso 15765-4 for communication protocol. The terminal arrangement of the dlc3 complies with iso 15031-03 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.
If the result is not as specified, the dlc3 may have a malfunction. Repair or replace the harness and connector.
