Reference Value

VALUES ON THE DIAGNOSIS TOOL 

NOTE: SYMBOL
  • 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. Example: The ignition timing shown by the timing light may differ from the ignition timing displayed on the data monitor. 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 .
