simulated vehicle speed. If you
connect M.U.T.-III main harness
B instead, the CAN
communication does not
function correctly.

NOTE: When the diagnosis codes relating to the LIN
communication error are set, make sure of the vehi-
cle equipment. When the vehicle is not equipped with
the system the ETACS-ECU communicates to, the
diagnosis code is always set. This is not abnormal.

TROUBLE JUDGEMENT
The ETACS-ECU receives signal from the column-
ECU. If signal cannot be received at all, diagnosis
code No.U1500 will be set.
COMMENT ON TROUBLE SYMPTOM
The M.U.T.-III shows a diagnosis code status as
active.
• Connector(s) or wiring harness in the LIN bus
lines between the column-ECU and the ETACS-
ECU, the power supply system of the column-
ECU, or the column-ECU itself may be defective.
The M.U.T.-III shows a diagnosis code status as
stored.
• If diagnosis code No.U1500 is stored as a past
trouble, carry out diagnosis with particular
emphasis on wiring and connector(s) in the LIN
bus line between the column-ECU and the
ETACS-ECU, and the power supply system of the
column-ECU. For diagnosis procedures, refer to
GROUP 00, How to Use Troubleshooting/Inspec-
tion Service Points
− How to Treat Past Trouble .
PROBABLE CAUSES
• Malfunction of the lighting switch
• Damaged harness wires and connectors
