No.3 i-ELOOP-RELATED GAUGE IN DISPLAY DOES NOT MOVE [i-ELOOP]

id130301003300

Description

• The i-ELOOP operation status indicated in display does not operate.

Possible Cause

Bypass Mode Is Operating

― Vehicle electric load (current consumption) is 50 A or more

― Voltage reduction circuit in DC-DC converter (i-ELOOP) is malfunctioning

― Battery charge condition is less than 65%

Instrument cluster incorrect display

• Instrument cluster malfunction

Other

• Engine-related part malfunction

• Transmission-related part malfunction

Diagnostic Procedure

STEP

INSPECTION

RESULTS

ACTION

1

VERIFY DTCs

•  Using the M-MDS, display the DTCs related to the PCM, TCM (ATX), and instrument cluster.
(See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

(See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].)

(See DTC INSPECTION [INSTRUMENT CLUSTER].)

•  Are any DTCs displayed?

Yes

Repair the malfunctioning part according to the applicable DTC troubleshooting.

(See DTC TABLE [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

(See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FW6A-EL].)

(See DTC TABLE [INSTRUMENT CLUSTER].)

No

Go to the next step.

2

VERIFY MALFUNCTION CONDITION

•  Verify the current display condition of the display.

•  Does the i-ELOOP-related gauge in the display operate?

Yes

Go to the next step.

No

Go to Step 4.

3

ASK CUSTOMER

•  Was the ambient temperature low when the symptom occurred?

Yes

Explain to the customer that the vehicle is normal and that i-ELOOP does not operate to assure battery power supply.

No

Explain to the customer that the vehicle is normal and that i-ELOOP does not operate to prioritize battery charging.

4

VERIFY BYPASS MODE OPERATION CONDITION

•  Access the DC-DC converter (i-ELOOP) PID BYPS_STAT using the M-MDS.
(See PID/DATA MONITOR INSPECTION [i-ELOOP].)

•  Is BYPS_STAT display “Bypass On”?

Yes

Go to the next step.

No

Inspect the instrument cluster and replace it if there is any malfunction.

(See INSTRUMENT CLUSTER INSPECTION.)

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

5

VERIFY CAUSE OF BYPASS MODE OPERATION

•  Access the following DC-DC converter (i-ELOOP) PIDs using the M-MDS:
(See PID/DATA MONITOR INSPECTION [i-ELOOP].)

―  DCDC_OUT_I

―  IR_LOAD_I (with i-stop)

•  Is the sum of the DCDC_OUT_I and IR_LOAD_I monitoring values 50 A or more?

Yes

Explain to the customer that the vehicle is normal and that i-ELOOP does not operate because of the vehicle electrical load.

No

Go to the next step.

6

VERIFY BATTERY CHARGE CONDITION

•  Access the PCM PID BATT_SOC using the M-MDS.
(See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 1.5, SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

•  Is BATT_SOC value less than 65%?

Yes

Explain to the customer that the vehicle is normal and that i-ELOOP does not operate to prioritize battery charging.

No

Inspect the instrument cluster and replace it if there is any malfunction.

(See INSTRUMENT CLUSTER INSPECTION.)

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
