Tech Tips
These DTCs can be stored after clearing DTCs and driving the vehicle for approximately 10 minutes.
These DTCs are stored when a malfunction is detected in the EV battery or a battery voltage sensor. However, depending on the driving conditions, the malfunction may not be reproduced if the status of the EV battery changes. If internal resistance is abnormal, the voltage of the battery blocks indicated by the DTCs are likely to decrease more than others blocks voltage during acceleration (discharging), and increase more during deceleration (charging).
When the EV battery is malfunctioning:
- Voltage of 1 or more of the battery blocks has dropped.
- Voltage of all battery blocks is output randomly with no certain pattern.
When the battery voltage sensor is malfunctioning:
- Differences in battery block voltages have a certain pattern.

Tech Tips
In order to ensure EV battery performance, appropriate cooling performance must be maintained. Perform the following items as necessary. If cooling performance has decreased and "MAINTENANCE REQUIRED FOR HYBRID BATTERY COOLING PARTS AT YOUR DEALER" is displayed on the multi-information display, make sure to perform the following items:
- Make sure the air intake port is not blocked.
- Make sure there are no gaps between the connecting parts of the ducts.
- Clean the No. 1 EV battery intake duct (filter).
Afterwards, clear the DTCs to reset the learning values even if no DTCs are stored.
CAUTION / NOTICE / HINT
Note
When the vehicle is parked with the power switch off, if the FC control ECU judges that the FC stack temperature will go below 0°C (32°F), it activates the FC air compressor, hydrogen pump and FC cooling water pump for a maximum of 180 seconds and drains water from the FC stack assembly. When performing inspection or repairs with the power switch off (not on (IG) or on (READY)), disconnect the cable from the negative (-) auxiliary battery terminal before performing work (If the auxiliary battery voltage is needed to conduct inspection, warm up the FC system beforehand).
Tech Tips
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
Drive the vehicle on urban roads for approximately 10 minutes.
(This DTC may not be stored if the vehicle is stopped or being driven at a constant speed.)
When disposing of an EV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the EV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.
