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

Inspection Procedure 1: Electric-folding door mirrors do not work at all.

CAUTION

• Whenever the ECU is replaced, ensure that 

the input and output signal circuits are nor-
mal.

• When the ETACS-ECU of vehicles without 

KOS is replaced, the encrypted code of the 
ignition key needs to be registered to the 
ETACS-ECU. (If the encrypted code is not reg-
istered, the engine cannot be started. Regis-
ter the encrypted code as described in 
GROUP 54A, Immobilizer System 

− How to 

Register Key ID )

OPERATION

The ETACS-ECU operates this function in accord-
ance with the input signals below.

• Ignition switch (ACC)

• Electric remote controlled mirror switch (fold-

ing/unfolding switch)

COMMENTS ON TROUBLE SYMPTOM

If the system does not work, the input circuit from the 
ignition switch (ACC) or the remote controlled mirror 
switch (folding/unfolding switch), or the ETACS-ECU 
may be faulty.

PROBABLE CAUSES

• Defective remote controlled mirror switch

• Defective ignition switch (ACC)

• Malfunction of ETACS-ECU

• Damaged wiring harness and connectors

DIAGNOSTIC PROCEDURE

STEP 1. M.U.T.-III diagnosis code
Check if an ETACS-related diagnosis code is set.

Q: Is the diagnosis code set?

YES : 

Troubleshoot the ETACS. (Refer to GROUP 

54A 

− ETACS, Diagnosis Code Chart .)

NO : 

Go to Step 2.
