(See DTC P0010-00: [PCM (SKYACTIV-G (WITHOUT Mazda M Hybrid))] .)
(See DTC P0011-00: OR P0012-00: [PCM (SKYACTIV-G (WITH Mazda M Hybrid))] .)
(See DTC P0011-00: OR P0012-00: [PCM (SKYACTIV-G (WITHOUT Mazda M Hybrid))] .)
(See DTC P0014-00: [PCM (SKYACTIV-G (VIN L (US)))] .)
(See DTC P0015-00: [PCM (SKYACTIV-G (VIN L (US)))] .)
(See DTC P1380-00: .)
(See DTC P2090-00: [PCM (SKYACTIV-G (VIN L))] .)
(See DTC P2091-00: [PCM (SKYACTIV-G (VIN L))] .)
Go to the next step.
No Go to the next step.
7 PURPOSE: VERIFY DTCs FOR MISFIRE
  • Perform the DTC inspection for the PCM. (See DTC INSPECTION .)
  • Are any of the following DTCs displayed?
    • P0300:00
    • P0301:00
    • P0302:00
    • P0303:00
      • P0304:00
 Yes Repair the malfunctioning location according to the applicable DTC troubleshooting.
(See DTC P0300-00: [PCM (SKYACTIV-G (US))] .)
(See DTC P0301:00, P0302:00, P0303-00: OR P0304-00: [PCM (SKYACTIV-G (US))] .)
Go to the next step.
No Go to the next step.
8 PURPOSE: VERIFY A/F SENSOR AND HO2S INPUT SIGNAL
  • Start the engine and warm it up completely.
  • Access the following PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION .)
    • A/F_SEN_CUR
      • HO2S_OUT_VOLT
  • Drive the vehicle under the following conditions.
    WARNING:
    • When the M-MDS is used to observe monitor system status while driving, be sure to have another technician with you, or record the data in the M-MDS using the PID/DATA MONITOR AND RECORD capturing function and inspect later.
    • While performing this step, always operate the vehicle in a safe and lawful manner.
      • After increasing the engine speed to 3, 000 RPM, decelerate using engine braking.
  • Is the displayed PID value as follows?
    • A/F_SEN_CUR: 0.25 mA or more
      • HO2S_OUT_VOLT: 0.3 V or less
 Yes Go to Step 10.
No Go to the next step.
9 PURPOSE: INSPECT RELATED SENSOR WIRING HARNESS AND CONNECTOR
  • Access the following PIDs using the M-MDS: (See PID/DATA MONITOR INSPECTION .)
    • A/F_SEN_CUR
      • HO2S_OUT_VOLT
  • When the PCM, A/F sensor and HO2S are shaken, does the PID value include a PID item which has changed?
 Yes Inspect the related wiring harness and connector.
  • Repair or replace the malfunctioning location.

Go to Troubleshooting Diagnostic Procedure to perform the repair completion verification.
No Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
10 PURPOSE: VERIFY IF MALFUNCTION CAUSED BY FUEL INJECTOR IMPROPER OPERATION
  • Start the engine and idle it.
  • Access the following simulation items using the M-MDS: (See SIMULATION INSPECTION .)
    • INJ
  • Using the simulation function, can the change in engine speed be verified when operation of each of the fuel injectors is stopped?
 Yes Go to the next step.
No Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 3.
11 PURPOSE: VERIFY IF MALFUNCTION CAUSED BY PURGE SOLENOID VALVE IMPROPER OPERATION
  • Start the engine and idle it.
  • Access the [EQUIVALENCE_RATIO_COMD] PID and simulation item PRG_DUTY using the M-MDS. (See PID/DATA MONITOR INSPECTION .) (See SIMULATION INSPECTION .)
  • Using the simulation function, does the [EQUIVALENCE_RATIO_COMD] PID value change when the purge solenoid valve is opened/closed?
