DTC P009D:00 [PCM (SKYACTIV-D 2.2)]

id0102j5228900

DTC P009D:00	Fuel pressure relief valve signal circuit high input
DETECTION CONDITION	•  With the following conditions met, the operation amount of the fuel pressure relief valve drive current control switch is the specification or more. ―  Battery positive voltage: 10—16 V ―  During fuel pressure relief valve operation Diagnostic support note •  This is a continuous monitor (CCM). •  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. •  FREEZE FRAME DATA/Snapshot data is available. •  DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	•  Inhibits engine-stop by i-stop control.
POSSIBLE CAUSE	•  Fuel pressure relief valve connector or terminal malfunction •  Short circuit in each wiring harness of PCM connector or terminal •  Fuel pressure relief valve malfunction •  PCM malfunction

Diagnostic Procedure

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION Note •  Recording can be facilitated using the screen capture function of the PC. •  Record the freeze frame data/snap shot data.	—	Go to the next step.
2	INSPECT FUEL PRESSURE RELIEF VALVE CONNECTOR CONDITION •  Switch the ignition OFF. •  Disconnect the fuel pressure relief valve connector. •  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector, then go to Step 6.
3	INSPECT PCM CONNECTOR CONDITION •  Disconnect the PCM connector. •  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector, then go to Step 6.
4	INSPECT EACH WIRING HARNESS IN FUEL PRESSURE RELIEF VALVE CIRCUIT FOR SHORT CIRCUIT •  Verify that the fuel pressure relief valve connector and the PCM connector are disconnected. •  Switch the ignition OFF. •  Inspect for continuity between fuel pressure relief valve terminals A and B (vehicle wiring harness side). •  Is there continuity?	Yes	Refer to the wiring diagram and verify if there is a common connector between the following terminals. •  Fuel pressure relief valve terminal A and PCM terminal 1DK •  Fuel pressure relief valve terminal B and PCM terminal 1DG If there is a common connector: ―  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short circuit to determine the malfunctioning location. ―  Repair or replace the malfunctioning location. If there is no common connector: ―  Repair or replace the malfunctioning wiring harness. Go to Step 6.
		No	Go to the next step.
5	INSPECT FUEL PRESSURE RELIEF VALVE •  Inspect the fuel pressure relief valve. (See FUEL PRESSURE RELIEF VALVE INSPECTION [SKYACTIV-D 2.2]) •  Is the fuel pressure relief valve normal?	Yes	Go to the next step.
		No	Replace the common rail, then go to the next step. (See COMMON RAIL REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
6	VERIFY THAT REPAIRS HAVE BEEN COMPLETED •  Reconnect all disconnected connectors and hoses. •  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC. (See CLEARING DTC [PCM (SKYACTIV-D 2.2)]) •  Start the engine and warm it up. •  Stop all electrical loads. (Such as A/C, headlights, blower fan, rear window defroster) •  Drive the vehicle on flat roads under the following conditions 4 times repeatedly. Warning •  Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured. 1.  Accelerate to 15 km/h and decelerate to 0 km/h. 2.  Wait for 20 s while idling. 3.  Accelerate to 30 km/h, and decelerate to 0 km/h after driving the vehicle while maintaining the speed for 20 s. 4.  Wait for 20 s while idling. 5.  Accelerate to 50 km/h, and decelerate to 0 km/h after driving the vehicle while maintaining the speed for 20 s. 6.  Wait for 20 s while idling. •  Accelerate to 70 km/h and drive the vehicle while maintaining the speed for 60 s. •  Decelerate to 50 km/h and drive the vehicle while maintaining the speed for 60 s. •  Accelerate to 70 km/h and drive the vehicle while maintaining the speed for 60 s. •  Accelerate to 100 km/h and drive the vehicle while maintaining the speed for 30 s. •  Accelerate to 120 km/h and decelerate to 0 km/h. •  Stop the engine. •  Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Has DTC P009D:00 been recorded?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
		No	Go to the next step.
7	VERIFY OTHER DTCs •  Has any other DTC or pending code been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)])
		No	DTC troubleshooting completed.
