STEP 1. Using scan tool (M.U.T.-IIISE), check the data list. <CMU>
(1) Operate the electric motor switch with depressing the brake pedal and turn ON the power supply mode of electric motor switch.
(2) Select "CMU" from System select Screen of the scan tool (M.U.T.-IIISE).
(3) Select the "Special Function" from the main CMU screen.
(4) Select the "Reset" from the Special Function screen
(5) Select the "EEPROM Failure information" from the Test screen.
(6) Set scan tool (M.U.T.-IIISE) to the CMU data list (Refer to ).- Item No.29: Microcomputer reference voltage
- Item No.30: IC reference voltage
- Item No.80: EEPROM Fail (learning data read)
- Item No.88: A/D conversion (Reference VOLT.)
OK: Normal
Is the check result normal?
Remove the battery tray cover (Refer to ). Replace the cell monitoring unit (CMU) corresponding to the diagnostic trouble code being set. Then, assemble the main drive lithium-ion battery assembly (Refer to ). Then go to Step 2. Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
