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 left door window glass travels further in the close direction exceeding
the fully-closed position, ETACS-ECU sets the diagnosis code No. 3003.
Past trouble
If the diagnosis code No. 3003 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 ).
