2016 Mazda 6 Grand TouringFACTORY OEM SERVICE PROCEDURE

Using The M-MDS

NOTE:
  1. Connect the M-MDS to the DLC-2.
  2. Switch the ignition ON (engine off).
  3. Measure the PID value.
    • If PID value is not within the specification, follow the instructions in action column.
NOTE:
  • The PID/DATA MONITOR function monitors the calculated value of the input/output signals in the PCM. Therefore, an output device malfunction is not directly indicated as a malfunction of the monitored value for the output device. If a monitored value of an output device is out of specification, inspect the monitored value of the input device related to the output control.
  • The simulation items that are used in the engine control system operation inspection are as follows.
    • ACCS, AIRSHUT_DSD*, ARPMDES, EVAPCP, EVAPCV, FAN1, FAN3, FP, INJ_1, INJ_2, INJ_3, INJ_4, OIL_P_SOL, Test, VT EX_DES

* If the active air shutter fully open/closed position learning is not completed, the active air shutter cannot be forcibly operated. When the active air shutter is forcibly operated, perform the active air shutter fully open/closed position learning.

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.
