•  Current sensor

FAIL-SAFE FUNCTION

•  Inhibits engine-stop by operating the i-stop function.

•  Inhibits engine-stop by operating the i-ELOOP function. (With i-ELOOP)

VEHICLE STATUS WHEN DTCs ARE OUTPUT

•  Illuminates the i-stop warning light (amber)

•  Illuminates the master warning light

•  The engine cannot be started or the engine may stall due to battery voltage decrease.

POSSIBLE CAUSE

•  Battery deterioration

•  Current sensor malfunction

•  Front body control module (FBCM) malfunction

•  PCM malfunction

Function Explanation (DTC Detection Outline)

• The battery assures voltage for engine starting and while the vehicle is being driven, and for the vehicle's electrical devices when the engine is stopped by i-stop. If the frequency of battery charging/discharging is high, the battery will deteriorate which could result in poor engine startability and the loss of assured supply voltage to the vehicle’s electrical load.

Repeatability Verification Procedure

1. Start the engine.

STEP

INSPECTION

RESULTS

ACTION

1

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.

2

PURPOSE: VERIFY IF BATTERY VOLTAGE IS FALSELY RECOGNIZED BY DTC RELATED CURRENT SENSOR

•  Switch the ignition to off, then to ON (engine off or on).

•  Perform the Pending Trouble Code Access Procedure and DTC Reading Procedure.
(See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-D 2.2].)

•  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 2.2].)

No

Go to the next step.

3

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 2.2].)

(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 2.2].)

(See DTC TABLE [FRONT BODY CONTROL MODULE (FBCM)].)

No

Go to the next step

4

PURPOSE: Verify if a malfunction occurred due to failure of performing the battery condition initial setting (i-stop setting).

•  Verify the “BATT_DAY”.

•  Has it only been a short while since the battery was replaced?

Yes

Verify the battery replacement record (servicing record or consultation with customer), and if it can be determined that the battery condition initial setting (i-stop setting) was not performed, perform the battery condition initial setting (i-stop setting).

Go to the troubleshooting procedure to perform the procedure from Step 2.

No

Go to the troubleshooting procedure to perform the procedure from Step 1.
