Function Inspection Using M-MDS

DIANOSTIC PROCEDURE - FUNCTION INSPECTION USING M-MDS

STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line 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: IDENTIFY TRIGGER DTC FOR FREEZE FRAME DATA Is the DTC P0087:00 on FREEZE FRAME DATA?	Yes	Go to the next step.
2		No	Go to the troubleshooting procedure for DTC on FREEZE FRAME DATA. (See DTC TABLE [PCM (SKYACTIV-G 2.5T)] .)
3	PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION 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 on the repair order.	-	Go to the next step.
4	PURPOSE: VERIFICATION IF MALFUNCTION CAUSED BY LACK OF FUEL Verify the snapshot data FLI. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)] .) Is the snapshot data FLI 5% or less?	Yes	Refill the fuel. Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 3.
4		No	Go to the next step.
5	PURPOSE: VERIFY RELATED PENDING CODE AND/OR DTC Switch the ignition off, then ON (engine off). Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)] .) Are any other PENDING CODEs and/or DTCs present?	Yes	Go to the applicable PENDING CODE or DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.5T)] .) Go to the next step.
5		No	Go to the next step.
6	PURPOSE: VERIFY CONNECTOR CONNECTIONS Start the engine. Access the FUEL_PRES PID using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)] .) Does the PID value fluctuate when the following connectors are shaken? High fuel pressure sensor PCM	Yes	Repair or replace the applicable wiring harness or connector parts. Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 3.
6		No	Go to the next step.
7	PURPOSE: VERIFY FUEL PRESSURE (LOW-SIDE) MALFUNCTION NOTE: Verify the fuel pressure on the low pressure side with the operation of the high pressure fuel pump turned off. Bleed the remaining pressure in the fuel line using the following procedure. Switch the ignition off. Disconnect the high pressure fuel pump connector. Disconnect the fuel pump relay. Start the engine and wait until the engine stalls. Switch the ignition off. Install the fuel pump relay. Switch the ignition ON (engine off). Display PID FUEL_PRES and simulation item FP using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)] .) Turn simulation item FP on. Is the FUEL_PRES PID value 550 kPa {5.61 kgf/cm² , 79.8 psi} or more?	Yes	Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 2.
7		No	Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.
