Symptom Diagnosis. Reduction in the Driving Range

Symptom Description

• The driving range is shorter than before.

• Sudden change (Decrease/increase) in possible travel distance indicated on the combination meter.

Diagnosis Procedure

CHECK AVERAGE ELECTRICITY CONSUMPTION

Check with the customer to see if the average electricity consumption is lower than before.

Is the average electricity consumption lower than before?

YES>>

Perform symptom diagnosis "Low electrical consumption". Refer to Diagnosis Procedure.

NO>>

GO TO 2.

CHECK LI-ION BATTERY TEMPERATURE WHILE CHARGING

Check Li-ion battery temperature while charging.

Is the Li-ion battery temperature low?

YES>>

Charge Li-ion battery with normal room temperature.

NO>>

GO TO 3.

CHECK LI-ION BATTERY CHARGE LEVEL GAUGE

Check the indication of the Li-ion battery charge level gauge.

Is "—" shown?

YES>>

GO TO 5.

NO>>

GO TO 4.

DISCHARGE OF LI-ION BATTERY

1. Set the Nissan Ariya vehicle to READY.

2. Set the vehicle, according to the following conditions.

   A/C set temperature	: Full hot
   A/C fan speed	: Maximum speed
   A/C air outlet	: Defroster
   Headlamp	: High beam ON
   Door glass	: Full open

3. Let Li-ion battery discharge until Li-ion battery charge level gauge shows "—".

>>

GO TO 5.

CHARGE OF LI-ION BATTERY

1. Charge Li-ion battery by normal charge until the level reaches full charge.

2. After completion of normal charge, check that the indication of Li-ion battery charge level gauge shows 100 %.

>>

GO TO 6.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT

1. Power switch ON and wait for 1 minute or more.

2. Power switch OFF.

3. Power switch ON and wait for 1 minute or more.

4. Check “Self Diagnostic Result” of “HIGH VOLTAGE BATTERY” and “HIGH VOLTAGE BATTERY 2”.

5. Check that DTC is detected.

Is any DTC detected?

YES>>

Perform diagnosis on the detected DTC. Refer to DTC Index.

NO>>

GO TO 7.

CHECK LI-ION BATTERY CHARGE LEVEL.

Check Li-ion battery charge level on combination meter.

Is Li-ion battery charge level low?

YES>>

Explain the customer that the symptom is due to a decrease in Li-ion battery charge level.

NO>>

Li-ion battery is normal. Electricity consumption may be worse. Perform symptom diagnosis “Low electricity consumption”. Refer to Diagnosis Procedure.
