HOW TO PERFORM CHASSIS NUMBER (CHASSIS NO.) WRITING


Write the Chassis Number (Chassis No.) of immobilizer system as following procedure.
The Chassis Number (Chassis No.) is stored in the EV-ECU, ETACS-ECU or electric motor control unit (EMCU) by the vehicle manufacture. If the Chassis No. to be stored in the EV-ECU, ETACS-ECU or EMCU is eliminated fraudulently, the electric motor warning lamp illuminates and Diagnostic Trouble Code (diagnosis code) No.P0630 (Chassisi No. not programmed) <EV-ECU, EMCU>, No.B1761 (Chassisi No. not programmed) <ETACS-ECU> is shown. When the EV-ECU, ETACS-ECU or EMCU is replaced, and entry of the Chassis No. necessary due to diagnosis code No. P0630 (Chassisi No. not programmed) <EV-ECU, EMCU>, No.B1761 (Chassisi No. not programmed) <ETACS-ECU>. Enter the Chassis No. in accordance with the procedure as follows:
