Code No.4003: P/W (RR) Above window position


caution Whenever the ECU is replaced, ensure that the input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM


Current trouble
  • If the rear right door window glass travels further in the close direction exceeding the fully-closed position, ETACS-ECU sets the diagnosis code No. 4003.
Past trouble
  • If the diagnosis code No. 4003 is set as past trouble, carry out diagnosis with particular emphasis on wiring and connector(s) in the CAN bus line. For diagnosis procedures, refer to How to cope with past trouble (Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Treat Past Trouble ).
    note For a past trouble, you cannot find it by the M.U.T.-III CAN bus diagnostics even if there is any failure in CAN bus lines. In this case, refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Treat Past Trouble and check the CAN bus lines. You can narrow down the possible cause of the trouble by referring to the diagnosis code, which is set regarding the CAN communication-linked ECUs (Refer to GROUP 54C - Explanation About The M.U.T.-III CAN Bus Diagnostics ).
