DTC P2BA3:00 [PCM (SKYACTIV-X)]

Home  id0102u9011100

Note

•  To determine the malfunctioning part, proceed with the diagnostics from “Function Inspection Using M-MDS”.

Details On DTCs

Description	Drive belt performance problem
Detection condition	Determination conditions	•  The PCM detects that the ratio between the engine speed and the integrated starter generator (ISG) rotation speed is not within the standard.
	Preconditions	•  Engine speed: 500 rpm or less*1 •  Integrated starter generator (ISG) rotation speed signal is received normally*1 *1: Standard can be verified by displaying PIDs using M-MDS.
	Malfunction determination period	•  5 s period
	Drive cycle	•  1
	Self test type	•  CMDTC self test
	Sensor used	•  PCM •  Integrated starter generator (ISG)
Fail-safe function	•  Inhibits engine-stop by operating the i-stop function. •  Inhibits the regenerative braking control.
Vehicle status when DTCs are output	•  If the vehicle continues to be driven while the DTC is detected the battery will be depleted. ―  A malfunction occurs with an electrical device and the vehicle stops. •  The following vehicle conditions differ depending on the type of malfunction: ―  Vehicle shock may occur due to generator load. ―  Idling feel due to generator-stop may occur.
Possible cause	•  CKP malfunction •  Integrated starter generator (ISG) malfunction (internal rotate sensor malfunction) •  Drive belt breakage •  Decoupling ring tensioner malfunction •  PCM malfunction

PID Item/Simulation Item Used In Diagnosis

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.
		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: INSPECT FOR OTHER RELATED DTCs •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Are any of the following DTCs displayed? ―  P0335:00	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC P0335:00 [PCM (SKYACTIV-X)].) Go to the next step.
		No	Go to the next step.
4	PURPOSE: INSPECT FOR OTHER RELATED DTCs •  Perform the DTC inspection for the integrated starter generator (ISG). (See DTC INSPECTION.) •  Are any of the following DTCs displayed? ―  P0A1E:00 ―  P0A4C:00 ―  P0A4D:00	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC P0A1E:00 [INTEGRATED STARTER GENERATOR (ISG)].) (See DTC P0A4C:00, P0A4D:00 OR P0A4E:00 [INTEGRATED STARTER GENERATOR (ISG)].) Go to Troubleshooting Diagnostic Procedure to perform the procedure from repair completion verification.
		No	Go to Troubleshooting Diagnostic Procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

―  Perform an inspection of the drive belt.

―  Verify that the primary malfunction is resolved and there are no other malfunctions.

Step	Inspection	Results	Action
1	PURPOSE: INSPECT DRIVE BELT FOR MALFUNCTION •  Verify the condition of the drive belt assembly. (See DRIVE BELT INSPECTION [SKYACTIV-X 2.0].) •  Is there any malfunction?	Yes	Assemble drive belt correctly and perform the repair completion verification. (See DRIVE BELT REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
		No	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the decoupling ring tensioner, then perform the repair completion verification. (See DECOUPLING RING TENSIONER REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
Repair completion verification 1	PURPOSE: VERIFY THAT VEHICLE IS REPAIRED •  Install/connect the part removed/disconnected during the troubleshooting procedure. •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Replicate the vehicle conditions at the time the DTC was detected using the following procedure. ―  Implement the repeatability verification procedure. (See Repeatability Verification Procedure.) •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is the same Pending DTC present?	Yes	Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error. (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(E)].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-X 2.0].)
		No	Go to the next step.
Repair completion verification 2	PURPOSE: VERIFY IF OTHER DTCs DISPLAYED •  Perform the DTC inspection. (See DTC INSPECTION.) •  Are any other DTCs displayed?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting.
		No	DTC troubleshooting completed.
