Function Inspection Using M-MDS

WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.
DIAGNOSTIC PROCEDURE - FUNCTION INSPECTION USING M-MDS

Step Inspection Results Action
1 PURPOSE: VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY
  • Verify related Service Bulletins, on-line repair information, or Service Information availability.
  • Is any related Information available?
 Yes Perform repair or diagnosis according to the available information.
  • If the vehicle is not repaired, go to the next step.
No Go to the next step.
2 PURPOSE: RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
  • Record the freeze frame data/snapshot data and diagnostic monitoring test results (EVAP system related).
    NOTE:
    • Recording can be facilitated using the screen capture function of the PC.
 - Go to the next step.
3 PURPOSE: INSPECTION OF CLOGGING BETWEEN FUEL TANK PRESSURE SENSOR AND FUEL TANK
  • Perform the DTC inspection for the PCM. (See DTC INSPECTION .)
  • Are any of the following DTCs displayed?
    • P144A:00
 Yes The possibility of clogging between fuel tank pressure sensor and fuel tank is high.
  • Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC P144A:00 .)
No Go to the next step.
4 PURPOSE: VERIFY FUEL TANK PRESSURE SENSOR MEASURED CORRECTLY
  • Start the engine and idle it.
  • Access the following simulation items using the M-MDS: (See SIMULATION INSPECTION .)
    • PRG_DUTY
      • CSTR_VENT_SOL_DUTY
  • Change to the following conditions using the simulation function.
    • PRG_DUTY: 100 %
      • CSTR_VENT_SOL_DUTY: 100 %
  • Access the FTP PID using the M-MDS.

    (See PID/DATA MONITOR INSPECTION .)

  • Does the negative pressure change when racing the engine?
 Yes Go to the next step.
No Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
5 PURPOSE: VERIFY IF ATMOSPHERE BETWEEN CV SOLENOID VALVE AND ATMOSPHERE CAN RELEASE
  • Access the following simulation items using the M-MDS: (See SIMULATION INSPECTION .)
    • PRG_DUTY
      • CSTR_VENT_SOL_DUTY
  • Change to the following conditions using the simulation function.
    • PRG_DUTY: 0 %
      • CSTR_VENT_SOL_DUTY: 0 %
  • Access the EVAP_PRES PID using the M-MDS. (See PID/DATA MONITOR INSPECTION .)
  • Is the displayed PID value as follows?
    • Approx. 2.6 V (barometric pressure)
 Yes Go to the next step.
No Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 2.
6 PURPOSE: VERIFY IF PURGE SOLENOID VALVE IS STUCK OPEN
  • Access the following simulation items using the M-MDS: (See SIMULATION INSPECTION .)
    • PRG_DUTY
      • CSTR_VENT_SOL_DUTY
  • Change to the following conditions using the simulation function.
    • PRG_DUTY: 0 %
      • CSTR_VENT_SOL_DUTY: 100 %
  • Access the FTP PID using the M-MDS. (See PID/DATA MONITOR INSPECTION .)
  • Is the FTP PID value negative pressure?
 Yes Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 6.
No Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
