Re-Calibration of Main Pack

MAIN BATTERY CAPACITY AUTOMATIC MEASUREMENT

 


note

  • Do not disconnect the battery cable from the auxiliary battery (-) terminal.
  • To improve the measuring accuracy, working at more than 10° C of the outside temperature is recommended.

1.Connect the diagnosis connector to the M.U.T.-III.
2.Perform the regular charging by connecting the regular charging cable.
3.Check that the charging lamp in the combination meter is lit and the battery is charging.
4.Check that the residual main battery level indicator shows 1 segment or more. If the residual main battery level indicator shows 0 segment, charge the main battery until the battery level indicator shows 1 segment or more.
5.Select the “BMU” from the System Select Screen of the M.U.T.-III.
6.Select the “Special Function” from the BMU Screen.
7.Select the “Main Battery Capacity Automatic Measurement” from the Special Function Screen and do it. If errors occur, restart from the step 2. When any malfunction has been found, perform troubleshooting.
8.Turn on the air conditioner under the following conditions.
<Air conditioner operating conditions>

  • Electric motor switch: LOCK
  • Air flow: largest
  • setting temperature: highest
  • A/C switch: ON
  • MAX switch: ON
note

  • Capacity measurement time can be reduced if executed while the power window is fully open compared to the execution while the power window is fully closed.
  • Check that the “Execution status” displayed on the M.U.T.-III is “Executing”. If “Not Completed” or “Not Executed” is displayed, check “Error state” , then restart from the step 2.
  • Check “Automatic Capacity Measurement Result History 1” and “Automatic Capacity Measurement ODO Value(Result History 1)” displayed on the M.U.T.-III.
