Code No. P1A5E: CMU01 battery cell high voltage abnormal, P1A5F: CMU02 battery cell high voltage abnormal, P1A60: CMU03 battery cell high voltage abnormal, P1A61: CMU04 battery cell high voltage abnormal, P1A62: CMU05 battery cell high voltage abnormal, P1A63: CMU06 battery cell high voltage abnormal, P1A64: CMU07 battery cell high voltage abnormal, P1A65: CMU08 battery cell high voltage abnormal, P1A66: CMU09 battery cell high voltage abnormal, P1A67: CMU10 battery cell high voltage abnormal, P1A68: CMU11 battery cell high voltage abnormal, P1A69: CMU12 battery cell high voltage abnormal


TROUBLE JUDGMENT
Check Conditions
  • 3 seconds elapse after the electric motor switch is turned ON, or 3 seconds elapse after the main battery starts to be charged.
  • None of the following diagnosis codes occur at the same time.

    1. P1AA8: Local CAN (for main battery) signal time-out
    2. U1082: Local CAN (for main battery) bus off
Judgement Criterion
  • The battery cell voltage is more than 4.2 V.

FAIL-SAFE AND BACKUP FUNCTION

  • Not available

PROBABLE CAUSE

  • The module (battery cell, CMU and battery cell voltage sensor) in the main battery is failed.

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III data list

  • Check the data list reference table corresponding to the diagnosis code (Refer to ).
OK: 4.2 V or less

Q. Is the check result normal?
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
Replace the main battery.
