P062F-00 Internal Control Module EEPROM Error: generic failure Overview: ISO Code P062F-00 Customer Symptom • Transmission fault lamp ON Fault Effects (On Vehicle) • Transmission fault lamp is ON Lamp Status (If Any) Transmission fault lamp ON (Service indication 0x1) Fault Detection Condition internal TCU error with reading and writing to memory (FFT 0ms) Normal Operating Condition DCT TCU communicated properly on vehicle CAN BUS. Probable Trouble Area TCU Damaged (internal TCU error (FFT 0ms)) Healing Condition The reaction is cleared during SW restart if the detection is FALSE.
