Refer to INSTALLATION [12/2023 - ]

HINT:  Perform this procedure when the No. 2 traction battery device box assembly or battery ECU assembly has been replaced.

1. Perform a road test.
   NOTE:

   Accelerate and decelerate gently. Avoid rapid acceleration and deceleration.

   1. Drive the vehicle with the value of Data List item "Hybrid/EV Battery Current" between -50 A and 50 A.

      Powertrain > HV Battery > Data List 

      Tester Display
      Hybrid/EV Battery Current

      HINT: 

      Distance and driving time are not specified.

   2. Turn the ignition switch off and leave the vehicle for 30 seconds or more.
   3. Check that the value of "Hybrid/EV Battery Current" is between -0.5 A and 0.5 A with the ignition switch to ON.

      Powertrain > HV Battery > Data List 

      Tester Display
      Hybrid/EV Battery Current

      NOTE:

      If the value is outside the specified range, perform the road test again.

      HINT: 

      • When the ignition switch to ON, if value of "Hybrid/EV Battery Current" is between -0.5 A and 0.5 A, current sensor offset learning has been completed.
      • Even if the current sensor offset learning is not complete, the current sensor value will be corrected by repeating the road test a maximum of 7 times.
