DTC P1A3B:00 [PCM (e-SKYACTIV)]

id300202035500

Outline

System malfunction location	Quick battery charge system: correlation problem
Detection condition	•  Any one of the following conditions is met: ―  The PCM detects a difference of 12 A or more between the electric current value detected by the charging equipment and the electric current value detected by the vehicle for 0.5 s during quick charge. ―  The PCM detects a difference of 10 V or more between the voltage value detected by the charging equipment and the voltage value detected by the vehicle for 0.5 s during quick charge.
Fail-safe	•  Refer to "DTC Table" and "Fail-safe Function Malfunction Contents Table". (See DTC TABLE [PCM (e-SKYACTIV)].)
Possible cause	•  Charging equipment malfunction High voltage battery malfunction •  High voltage battery internal parts malfunction •  PCM malfunction
System wiring diagram	•  Not applicable
Connector diagram	•  Not applicable

Diagnostic Procedure

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 •  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 PCM. (See DTC INSPECTION.) •  Is DTC P1A3B:00 a present malfunction? Note •  If DTC P1A3B: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.
3	VERIFY WHETHER MALFUNCTION IS PRESENT OR PAST AGAIN •  Switch the main power to OFF •  Switch the main power to ON (READY on) •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is DTC P1A3B:00 a present 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 malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION.)
		No	Go to the repair completion verification 2.
4	INSPECT HIGH VOLTAGE BATTERY FOR MALFUNCTION DEPENDING ON REPEATABILITY •  Switch the main power to OFF •  Switch the main power to ON (READY on) •  Perform the DTC inspection for the PCM. (See DTC INSPECTION.) •  Is DTC P1A3B:00 a present 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 high voltage battery, then go to the next step. (See HIGH VOLTAGE BATTERY REMOVAL/INSTALLATION.)
		No	Go to the next step.
Repair completion verification	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.
