Test Drive Confirmation

  1. Test drive confirmation may be performed to operate vehicle under conditions which may cause DTC to be set. When performing test drive confirmation, procedures must be performed exactly as listed or the malfunction may not be detected. If Toyota hand-held tester is available, go to next step. If Toyota hand-held tester is not available, go to step  3.
  2. Connect hand-held tester to Data Link Connector (DLC) No. 3 at driver's side of instrument panel. See Figure. Switch hand-held tester from NORMAL mode to CHECK mode.
  3. Start engine. Allow engine to idle for at least 60 seconds.
  4. Drive vehicle at 24 MPH or more for at least 40 seconds and then allow engine to idle for at least 10 seconds. Repeat this procedure 9 times and then check operation of Malfunction Indicator Light (MIL). If MIL illuminates, malfunction exists and DTC is set. If MIL does not illuminate, malfunction does not exist.
