Step 15. Check the wiring harness between C-220 
ETACS-ECU connector terminal Nos.31, 40 and 
F-13 door mirror assembly (RH) connector 
terminal Nos.7, 6.

NOTE: 

Prior to the wiring harness inspection, check 
intermediate connector C-14 and junction block 
connector C-32 <L.H drive vehicles>, and repair if 
necessary.

• Check the input and output signal line for open 

circuit.

Q: Is the check result normal?

YES : 

Go to Step 16.

NO : 

Repair the wiring harness.

Step16. Retest the system.
Check that the electric retractable remote controlled 
mirror works normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Replace the ETACS-ECU.

SYMPTOM PROCEDURES

SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR

54B-264

Inspection Procedure J-3: Electric retractable remote controlled door mirror timer function does not 
at all.

CAUTION

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

COMMENTS ON TROUBLE SYMPTOM

If the door mirror can be folded and unfolded with the 
remote controlled mirror switch (fold/unfold switch), 
the ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the driver’s door switch

• Malfunction of the ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check the electric folding door mirrors 
operation.
Check that the door mirror is folded and unfolded 
with the remote controlled mirror switch when the 
ignition switch is at ACC position.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to inspection procedure J-1 "The 
electric retractable remote controlled door 
mirrors does not work at all 

P.54B-250

."

Step 2. Pulse check
Check the input signals below which are related to 
the electric retractable remote controlled door mirror 
timer function.

OK: The MUT-III sounds or the voltmeter 
needle fluctuates.

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Refer to inspection procedure Q-1 "The 
ignition switch (ACC) signal is not received 

P.54B-416

."

Step 3. Retest the system.
Check that the electric-folding door mirror timer 
function works normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

Cope with Intermittent Malfunction 

P.00-5

).

NO : 

Replace the ETACS-ECU.
