STEP 3. Retest the system.
Check that the electric-folding door mirror timer func-
tion works normally.

Q: Is the check result normal?

YES : 

Intermittent malfunction (Refer to GROUP 

00 - How to Use Troubleshooting/Inspection 
Service Points - How to Cope with 
Intermittent Malfunction .)

NO : 

Replace ETACS-ECU.

Inspection Procedure 4: Vehicle speed-dependent unfolding function does not work normally.

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 calculates the intermittent wiper 
interval according to the vehicle speed signal which 
is sent by the ABS-ECU <Vehicles without ASC> or 
ASC-ECU <Vehicles with ASC>.

• Ignition switch (IG1)

COMMENTS ON TROUBLE SYMPTOM

If this function does not work normally, these input 
signal circuit(s) or the ETACS-ECU may be defec-
tive. Also, with a customise function, the door mirrors 
may be set to a mode in which the vehicle 
speed-dependent unfolding function is not activated.

PROBABLE CAUSES

• Faulty vehicle speed signal

• The CAN bus line is defective.

• Malfunction of ETACS-ECU

DIAGNOSTIC PROCEDURE

STEP 1. Check the ETACS customise function.
Use the ETACS customise function to confirm that 
"AUTO FOLD MIRROR" is set to "VEHICLE SPEED 
DEPENDENT OPEN". 

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Use the ETACS customise function to set 
"AUTO FOLD MIRROR" to "VEHICLE 
SPEED DEPENDENT OPEN" (Refer to ).

STEP 2. M.U.T.-III CAN bus diagnostics
Use M.U.T.-III to diagnose the CAN bus lines.

Q: Is the CAN bus normal?

YES : 

Go to Step 3.

NO : 

Repair the CAN bus line. (Refer to GROUP 
54C - Troubleshooting .)

STEP 3. M.U.T.-III diagnosis code.
Check that the ETACS-ECU sets a diagnosis code.

Q: Is the diagnosis code set?

YES : 

Diagnose the ETACS.(Refer to GROUP 

54A 

− ETACS, Diagnosis Code Chart .)

NO : 

Go to Step 4.

STEP 4. M.U.T.-III other system diagnosis code
Check that the ABS-ECU<Vehicles without ASC> or 
ASC-ECU <Vehicles with ASC> sets a diagnosis 
code.

Q: Is the diagnosis code set?

YES : 

Diagnose the ABS-ECU <Vehicles without 

ASC> (Refer to GROUP 35B 

− Diagnosis 

Code Chart ) or ASC-ECU <Vehicles with 
ASC> (Refer to GROUP 35C 

− Diagnosis 

Code Chart .

NO : 

Go to Step 5.

STEP 5. Retest the system.
Check that the vehicle speed-dependent unfolding 
function of the door mirrors works normally.

Q: Is the check result normal?

YES : 

Intermittent malfunction (Refer to GROUP 

00 - How to Use Troubleshooting/Inspection 
Service Points - How to Cope with 
Intermittent Malfunction .)

NO : 

Replace ETACS-ECU.

Inspection Procedure 5: Ignition-linked fold/unfold function does not work normally.

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

− How to 

Register Key ID )

OPERATION

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

• Ignition switch (IG1)

• Driver’s door switch

COMMENTS ON TROUBLE SYMPTOM

If this function does not work normally, these input 
signal circuit(s) or the ETACS-ECU may be defec-
tive. Also, with the customise function, the door mir-
rors may be set to a mode in which the ignition 
interlock fold/unfold function is not activated.

PROBABLE CAUSES

• Malfunction of the driver’s door switch

"AUTO FOLD MIRROR" is set to "IG OPEN OR 
CLOSE". 

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Use the ETACS customise function to set 
"AUTO FOLD MIRROR" to "IG OPEN OR 
CLOSE" (Refer to ).

STEP 2. M.U.T.-III data list

Inspection Procedure 6: Keyless entry system-linked fold/unfold function does not work normally.

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 keyless entry transmitter input signals.

COMMENTS ON TROUBLE SYMPTOM

If this function does not work normally, keyless entry 
transmitter input signal circuit or the ETACS-ECU 
may be defective. Also, with the customise function, 
the door mirrors may be set other than to the keyless 
entry interlock fold/unfold function.

PROBABLE CAUSES

• Defective keyless entry transmitter

• Malfunction of the ETACS-ECU

• Damaged wiring harness and connectors

DIAGNOSTIC PROCEDURE

"AUTO FOLD MIRROR" is set to "KEYLESS OPEN 
OR CLOSE". 

Q: Is the check result normal?

00 

− How to Use 

Troubleshooting/Inspection Service Points - 
How to Cope with Intermittent Malfunction ).

NO : 

Replace the ETACS-ECU.

defogger switch is turned on. If the mirror heater 
does not work for the specified period, the defogger 
relay circuit (heated door mirror power supply circuit) 
may be defective.

POSSIBLE CAUSES

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Check the rear window defogger.
Check that the rear window defogger system should 
work normally. (Refer to GROUP 54A, Printed heater 
check .)
