id0102j5215100

DTC P24A5:00	EGR cooler bypass valve system: EGR cooler bypass valve stuck
DETECTION CONDITION	•  When the following conditions are met, a condition whereby the EGR cooler bypass valve opening angle of 10% or more for 1 s or more is detected a total of 4 times, or continues for 1 min. ―  Execution of EGR cooler bypass valve fully closed control ―  The following DTCs are not stored •  EGR cooler bypass valve position sensor: P2494:00, P2495:00 •  EGR cooler bypass valve control system: P245A:00, P245B:00 •  Constant voltage power supply control system: P0652:00, P0653:00 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	•  Limits engine torque. •  Inhibits the automatic diesel particulate filter regeneration control. •  Inhibits the manual diesel particulate filter regeneration control. •  Inhibits the EGR control. •  Inhibits engine-stop by i-stop control.
POSSIBLE CAUSE	•  EGR cooler bypass valve stuck •  EGR cooler bypass valve/EGR cooler bypass valve position sensor connector or terminal malfunction •  EGR cooler bypass valve position sensor malfunction •  EGR cooler bypass valve malfunction •  PCM connector or terminal 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	DETERMINE IF MALFUNCTION CAUSE IS EGR COOLER BYPASS VALVE POSITION SENSOR MALFUNCTION •  Start the engine and idle it. •  Set the EGR_C_BP value to 0% using the simulation function. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Display the PID EGR_C_BP_ACT. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Does the PID EGR_C_BP_ACT value conform to the override operation using the simulation function?	Yes	Go to the next step.
		No	Go to Step 4.
3	VERIFY EGR VALVE CONTROL, EGR COOLER BYPASS VALVE CONTROL •  Using the simulation function, change the EGRP, EGR_C_BP values (%) and verify that the EGRP, EGR_C_BP values comply. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Do the EGRP, EGR_C_BP values comply?	Yes	Go to Step 8.
		No	Go to the next step.
4	INSPECT EGR COOLER BYPASS VALVE/EGR COOLER BYPASS VALVE POSITION SENSOR CONNECTOR CONDITION •  Switch the ignition OFF. •  Disconnect the EGR cooler bypass valve/EGR cooler bypass valve position sensor 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 8.
5	INSPECT EGR COOLER BYPASS VALVE POSITION SENSOR •  Reconnect all the disconnected connectors. •  Inspect the EGR cooler bypass valve position sensor. (See EGR COOLER BYPASS VALVE POSITION SENSOR INSPECTION [SKYACTIV-D 2.2]) •  Is the EGR cooler bypass valve position sensor normal?	Yes	Go to the next step.
		No	Replace the EGR cooler bypass valve, then go to Step 8. (See EGR COOLER BYPASS VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
6	EGR COOLER BYPASS VALVE INSPECTION •  Inspect the EGR cooler bypass valve. (See EGR COOLER BYPASS VALVE INSPECTION [SKYACTIV-D 2.2]) •  Is the EGR cooler bypass valve normal?	Yes	Go to the next step.
		No	Replace the EGR cooler bypass valve, then go to Step 8. (See EGR COOLER BYPASS VALVE REMOVAL/INSTALLATION [SKYACTIV-D 2.2])
7	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 the next step.
8	VERIFY THAT REPAIRS HAVE BEEN COMPLETED •  Reconnect all the disconnected connectors. •  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. •  Start the engine and drive the vehicle under the freeze frame data/snapshot data condition. Warning •  To prevent an accident, work with another person when the vehicle is being driven (one person drives vehicle, other person operates M-MDS). •  Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured. •  Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)]) •  Has DTC P24A5:00 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.
9	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.
