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.


    1. Turn the power switch on (IG) and wait for 10 seconds or more.

  • The interlock switch opens when the service plug grip is removed.

  • 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.
