VALUES ON THE DIAGNOSIS TOOL
Remarks:
● Specification data are reference values.
● Specification data are output/input values which are detected or supplied by the ECM at the connector.
* Specification data may not be directly related to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before monitoring IGN TIMING, because the monitor may show the specification data in spite of the
ignition timing not being adjusted to the specification data. this IGN TIMING monitors the data calculated by the ECM according to the signals
input from the camshaft position sensor and other ignition timing related sensors.
Monitor Item Condition Values/Status
ENG SPEED Run engine and compare CONSULT-III value with the tachometer indication.Almost the same speed as
the tachometer indication.
