DIAGNOSTIC PROCEDURE - FUNCTION INSPECTION USING M-MDS

STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or online repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	PURPOSE: RECORD FREEZE FRAME DATA/SNAPSHOT DATA AND DIAGNOSTIC MONITORING TEST RESULTS TO UTILIZE WITH REPEATABILITY VERIFICATION NOTE: Recording can be facilitated using the screen capture function of the PC. Record the FREEZE FRAME DATA/snapshot data and DIAGNOSTIC MONITORING TEST RESULTS (EVAP system related) on the repair order.	-	Go to the next step.
3	PURPOSE: INSPECTION OF CLOGGING BETWEEN FUEL TANK PRESSURE SENSOR AND FUEL TANK Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ). Is the PENDING CODE/DTC P144A:00 also present?	Yes	The possibility of clogging between fuel tank pressure sensor and fuel tank is high. Go to the applicable PENDING CODE or DTC inspection. (See DTC P144A:00 [PCM (VIN Y)] ).
3		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 ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ). EVAPCP EVAPCV Change to the following conditions using the simulation function. EVAPCP: 100% EVAPCV: On Access the FTP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ). Does the negative pressure change when racing the engine?	Yes	Go to the next step.
4		No	Go to the 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 ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ). EVAPCP EVAPCV Change to the following conditions using the simulation function. EVAPCP: 0% EVAPCV: Off Access the FTP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ). Is the displayed PID value as follows? Approx. 2.6 V (barometric pressure)	Yes	Go to the next step.
5		No	Go to the 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 ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ). EVAPCP EVAPCV Change to the following conditions using the simulation function. EVAPCP: 0% EVAPCV: On Access the FTP PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] ). Is the FTP PID value negative pressure?	Yes	Go to the Troubleshooting Diagnostic Procedure to perform the procedure from Step 5.
6		No	Go to the Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
