Toyota RAV4 Service Manual: Diagnosis system

  1. Description

  1. 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.

  1. Check dlc3

  1. 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.
