id0102q2569100

Note

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

Details On DTCs

DESCRIPTION	Power system: Low input
DETECTION CONDITION	Determination conditions	•  Any one of the following conditions is met: ―  Battery voltage is 11 V or less when ignition is switched off after leaving vehicle for 30 days or more. ―  Battery voltage is 11 V or less for a continuous 5 days when ignition is switched off.
	Preconditions	•  Difference in battery voltage for 30 min since ignition was switched off is specified value or less •  Electrical current from battery for 30 min since ignition was switched off is within specified value
	Drive cycle	•  1
	Self test type	•  CMDTC self test
	Sensor used	•  Current sensor
FAIL-SAFE FUNCTION	•  Not applicable
VEHICLE STATUS WHEN DTCs ARE OUTPUT	•  Flashes i-stop warning light (amber). •  The engine cannot be started or the engine may stall due to battery voltage decrease.
POSSIBLE CAUSE	•  Battery malfunction •  Current sensor malfunction •  Front body control module (FBCM) malfunction •  PCM malfunction

PID Item/Simulation Item Used In Diagnosis

Function Inspection Using M-MDS

STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION Note •  Recording can be facilitated using the screen capture function of the PC. •  Record the snapshot data on the repair order.	—	Go to the next step.
2	PURPOSE: VERIFY RELATED SERVICE INFORMATION AVAILABILITY •  Verify related Service Information availability. •  Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. •  If the vehicle is not repaired, go to the next step.
		No	Go to the next step.
3	PURPOSE: VERIFY IF BATTERY VOLTAGE IS FALSELY RECOGNIZED BY DTC RELATED CURRENT SENSOR •  Switch the ignition off, then ON (engine off). •  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) •  Is the PENDING CODE/DTC P058A:00 also present?	Yes	Go to the applicable PENDING CODE or DTC inspection. (See DTC P058A:00 [SKYACTIV-D 1.5].) Go to the next step.
		No	Go to the next step.
4	PURPOSE: VERIFY IF BATTERY VOLTAGE IS FALSELY RECOGNIZED BY DTC RELATED CAN OR LIN COMMUNICATION •  Perform the PCM and front body control module (FBCM) DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) (See DTC INSPECTION [FRONT BODY CONTROL MODULE (FBCM)].) •  Are DTCs related CAN or LIN communication recorded?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [SKYACTIV-D 1.5].) (See DTC TABLE [FRONT BODY CONTROL MODULE (FBCM)].) Go to the troubleshooting procedure to perform the procedure from Step 1.
		No	Go to the troubleshooting procedure to perform the procedure from Step 1.

Troubleshooting Diagnostic Procedure

―  Perform a unit inspection of the battery.

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

STEP	INSPECTION	RESULTS	ACTION
1	PURPOSE: DETERMINE INTEGRITY OF BATTERY •  Inspect the battery. (See BATTERY INSPECTION [SKYACTIV-D 1.5].) •  Is there any malfunction?	Yes	Replace the battery, then go to the next step. (See BATTERY REMOVAL/INSTALLATION [SKYACTIV-D 1.5].)
		No	Go to the next step.
2	PURPOSE: VERIFICATION OF VEHICLE REPAIR COMPLETION •  Always reconnect all disconnected connectors. •  Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [SKYACTIV-D 1.5].) •  Implement the repeatability verification procedure. (See Repeatability Verification Procedure.) •  Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 1.5].) •  Is the same DTC present?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 1.5].) Go to the next step.
		No	Go to the next step.
3	PURPOSE: VERIFY IF THERE IS ANY OTHER MALFUNCTION •  Is any other DTC or pending code stored?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-D 1.5].)
		No	DTC troubleshooting completed.
