Code No. P062F: EEPROM Malfunction <Euro5b>


FUNCTION



  • To check whether the information such as the idle learned value and so on is stored in the memory of engine-ECU.

TROUBLE JUDGMENT


Check Condition
  • Ignition switch is in "ON" position
Judgement Criterion
  • When the abnormal EEPROM memory data is detected.

PROBABLE CAUSE



  • Failed engine-ECU

DIAGNOSIS PROCEDURE

STEP 1. M.U.T.-III diagnosis codes.

Q. Is the check result normal?
Replace the engine-ECU. When the engine-ECU is replaced, write the chassis number (Refer to GROUP 00 - Precautions Before Service - How to Perform Chassis Number Writing ). After replacing the engine-ECU, register the injector identification code and learn fuel injection (Refer to GROUP 00 - Precautions Before Service - What The Common Rail Engine Learns ). After registering the injector identification code, the vehicle equipped with the closed type DPF carries out the forcible DPF regeneration. (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System - Forcible DPF Regeneration ).
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
