Values On The Diagnosis Tool

NOTE:
  • The following table includes information (items) inapplicable to this vehicle. For information (items) applicable to this vehicle, refer to CONSULT display items.
  • Numerical values in the following table are reference values.
  • These values are input/output values that ECM receives/transmits and may differ from actual operations.

    This occurs because the timing light shows a value calculated by ECM according to signals received from the camshaft position sensor and other sensors related to ignition timing.

  • For outlines of following items, refer to "CONSULT FUNCTION ".
