Remarks:
l Specification data are reference values.
l 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 TIM-
ING 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.
