id300204057900

Warning

<<High voltage>>

•  If the necessary measures are not taken before servicing an electric vehicle, it could cause electrical shock and result in serious injury or, in the worst case, death. Before servicing the electric vehicle, refer to [HIGH VOLTAGE SERVICE CAUTIONS] in the general information and implement the necessary measures. (See HIGH VOLTAGE SERVICE CAUTIONS.)

Outline

System malfunction location	Charging state control signal: Low frequency
Detection condition	•  The battery charge control module (onboard charger) detects that the frequency is low in the charging status control signal that is input to the battery charge control module (onboard charger) from the charging equipment.
Fail-safe	•  Stops charging
Possible cause	•  Charging equipment malfunction •  Battery charge control module (onboard charger) malfunction
System wiring diagram	•  Not applicable
Connector diagram	•  Not applicable

Diagnostic Procedure

Warning

<<High voltage>>

•  If necessary measures such as wearing the correct protective gear are not taken when inspecting or removing/installing the high voltage parts, it could cause electrical shock and result in serious injury or, in the worst case, death.

•  Before inspecting or removing/installing the high voltage parts, refer to [HIGH VOLTAGE SERVICE CAUTIONS] in the general information and [High Voltage Part Inspection and Removal/Installation Notes] of the high voltage system service cautions and implement the necessary measures and preparations. (See HIGH VOLTAGE SERVICE CAUTIONS.) (See HIGH VOLTAGE SYSTEM SERVICE CAUTIONS.)

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION •  Record the snapshot data. Note •  Recording can be facilitated using the screen capture function of the PC.	—	Go to the next step.
2	DETERMINE IF MALFUNCTION IS ON CHARGING EQUIPMENT SIDE •  Perform quick charging using charging equipment other than that used when the DTC was output. •  Perform the DTC inspection for the battery charge control module. (See DTC INSPECTION.) •  Is DTC P0E72:00 displayed as a current malfunction? Note •  If DTC P0E72:00 is displayed as a past malfunction, a malfunction in the charging equipment used when the DTC was output can be considered.	Yes	Go to the next step.
		No	The system is normal. (Explain to the customer that there is a possibility that a malfunction was detected due to a charging equipment malfunction.) Go to the repair completion verification 2.
3	INSPECT FOR OTHER RELATED DTCs •  Perform the DTC inspection for the battery charge control module. (See DTC INSPECTION.) •  Are any of the following DTCs displayed? ―  P0CF5:00 ―  P0CF7:00	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC P0CF5:00 [BATTERY CHARGE CONTROL MODULE (e-SKYACTIV (E))].) (See DTC P0CF7:00 [BATTERY CHARGE CONTROL MODULE (e-SKYACTIV (E))].)
		No	Go to the next step.
4	INSPECT BATTERY CHARGE CONTROL MODULE (ONBOARD CHARGER) FOR MALFUNCTION DEPENDING ON REPEATABILITY •  Install/connect the part removed/disconnected during the troubleshooting procedure. •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Perform quick charging using charging equipment other than that used when the DTC was output. •  Perform the DTC inspection for the Battery charge control module. (See DTC INSPECTION.) •  Is DTC P0E72:00 displayed as a current malfunction?	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 [L.H.D. (E)].) (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the onboard charger, then go to the repair completion verification 2. (See ONBOARD CHARGER REMOVAL/INSTALLATION.)
		No	Go to the repair completion verification 2.
Repair completion verification 1	VERIFY THAT VEHICLE IS REPAIRED •  Clear the DTC recorded in the memory. (See CLEARING DTC.) •  Perform quick charging using charging equipment other than that used when the DTC was output. •  Perform the DTC inspection for the Battery charge control module. (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 [L.H.D. (E)].) (See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [R.H.D.].) If the CAN communication is normal, perform the diagnosis from Step 1. •  If the malfunction recurs, replace the onboard charger, then go to the next step. (See ONBOARD CHARGER REMOVAL/INSTALLATION.)
		No	Go to the next step.
Repair completion verification 2	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.
