P3000-389

  • Battery Block Voltage -V01 to V17

  • State of Charge (All Battery)

  • VB-Battery Voltage

  • IB-Battery Current

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


  • Thoroughly interview the customer as DTC P3000-389 may be stored if the SOC drops due to running out of fuel.

  • When the FC system cannot be started, DTC P3000-389 may be stored because the EV battery cannot be charged.

  • 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).

    2. Enter the following menus: Powertrain / FC / Data List / FC Mode, FC Intermittent Operation.

    3. Move the shift lever to P, turn the power switch on (READY) and wait until the FC system is activated. Waiting for at least 2 minutes is required after turning the power switch on.


      • - FC system is activated: Data List shows that "FC Mode" is "FC Working" and "FC Intermittent Operation" is "OFF".

    4. Wait until the Data List (FC) item "FC Intermittent Operation" turns ON.

  • 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.
