Engine Tune-up Preparation: Notes

WARNING: This page is about a different car, the 2017 Mazda CX-5. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • If the accelerator pedal is depressed continuously for a specified time, the engine speed may decrease to the idle speed. This is due to the fuel cut control operation, which prevents overheating, and it does not indicate a malfunction. The engine speed returns to normal control when the accelerator pedal is released.
  1. Connect the M-MDS to the DLC-2.
  2. Shift the selector lever (ATX) or shift lever (MTX) to the following position:
    • MTX: Shift lever is in neutral position.
    • ATX: Selector lever is in P position or N position.
    NOTE:
    • The engine coolant temperature and oil temperature can be verified by M-MDS PID "ECT" and "OIL_TEMP".
  3. Run the engine speed at a constant 2, 500 to 3, 000 rpm and warm up the engine (engine coolant temperature: 80 °C {176 °F} or more, oil temperature: 60 °C {140 °F} or more).
  4. Turn off all electrical loads with the engine idling.
  5. If the cooling fan is operating, wait until is stops.
