CONSULT-II Reference Value in Data Monitor

WARNING: This page is about a different car, the 2006 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.

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.
