Using WDS Or External Diagnostic Equipment

CAUTION:
  • If the engine speed exceeds the allowable range, the engine could be damaged. Therefore, when inspecting the tachometer, do not allow the engine speed to exceed the allowable range indication on the tachometer.
  1. Connect the WDS or external diagnostic equipment to the diagnostic connector 2 (16-pin).
  2. Compare the data monitor item (RPM) with the tachometer indication.
    • If the tachometer does not operate properly inspect the PCM and related wiring harnesses.
      • If the PCM and related harnesses do not have any malfunction, replace the instrument cluster.
