For Using OBD II Scan Tool Or Hand-Held Tester

NOTE:
  • Before using the scan tool or tester, the scan tool's instruction book or tester's operator manual should be read thoroughly.
  • If the scan tool or tester cannot communicate with the ECU controlled systems when you have connected the cable of the scan tool or tester to the DLC3, turned the ignition switch ON and operated the scan tool, there is a problem on the vehicle side or tool side.
    1. If the communication is normal when the tester is connected to another vehicle, inspect the diagnosis data link line (Bus(+)line) or ECU power circuit of the vehicle.
    2. If the communication is still impossible when the tester is connected to another vehicle, the problem is probably in the tester itself, so perform the Self Test procedures outlined in the Tester Operator's Manual.
