2006 Infiniti QX56 RWDFACTORY OEM SERVICE PROCEDURE

CONSULT-II Reference Value in Data Monitor

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.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
