Code No. P1AB5: CMU01 module temperature abnormal (low input), P1AB6: CMU02 module temperature abnormal (low input), P1AB7: CMU03 module temperature abnormal (low input), P1AB8: CMU04 module temperature abnormal (low input), P1AB9: CMU05 module temperature abnormal (low input), P1ABA: CMU06 module temperature abnormal (low input), P1ABB: CMU07 module temperature abnormal (low input), P1ABC: CMU08 module temperature abnormal (low input), P1ABD: CMU09 module temperature abnormal (low input), P1ABE: CMU10 module temperature abnormal (low input), P1ABF: CMU11 module temperature abnormal (low input), P1AC0: CMU12 module temperature abnormal (low input)


TROUBLE JUDGEMENT
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 module temperature is less than -30°C or more than 60°C.

FAIL-SAFE AND BACKUP FUNCTION

  • Not available

PROBABLE CAUSE

  • The module (battery cell, CMU and module temperature 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: At ambient temperature (atmospheric temperature) or equivalent (when the vehicle driving and the charge are not performed for a long time)

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.
