Function Inspection Using M-MDS

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.
1		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. NOTE: Recording can be facilitated using the screen capture function of the PC.	-	Go to the next step.
3	PURPOSE: VERIFY IF FUEL TANK PRESSURE SENSOR HAS MALFUNCTION Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Are any of the following DTCs displayed? P0452:00 P0453:00 P0454:00	Yes	The possibility of a fuel tank pressure sensor malfunction is high. Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC P0452:00 .) (See DTC P0453:00 .) (See DTC P0454:00 .)
3		No	Go to the next step.
4	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 .)
4		No	Go to the next step.
5	PURPOSE: VERIFY IF CV SOLENOID VALVE HAS MALFUNCTION Perform the DTC inspection for the PCM. (See DTC INSPECTION .) Are any of the following DTCs displayed? P0446:00	Yes	The possibility of a CV solenoid valve malfunction is high. Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC P0446:00 .)
5		No	Go to the next step.
6	PURPOSE: VERIFY IF FUEL TANK PRESSURE IS STUCK TO EITHER LOW OR HIGH PRESSURE SIDE Start the engine and idle it. Access the FTP PID using the M-MDS. (See PID/DATA MONITOR INSPECTION .) Is the FTP PID value 0.424 kPa {0.00432 kgf/cm² , 0.0615 psi} or more?	Yes	The possibility that the fuel tank pressure is stuck to the high pressure side is high. Go to the next step.
6		No	The possibility that the fuel tank pressure is stuck to the low pressure side is high. Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 4.
7	PURPOSE: VERIFY IF MALFUNCTION CAUSE IS FREEZING OF FUEL TANK PRESSURE SENSOR BY VERIFYING AMBIENT TEMPERATURE Start the engine and idle it. Access the AMB_AIR_TEMP PID using the M-MDS. (See PID/DATA MONITOR INSPECTION .) Is the AMB_AIR_TEMP PID value 0°C {32°F} or less?	Yes	The possibility of a malfunction caused by freezing of the fuel tank pressure sensor is high. Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
7		No	Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 2.
