P.51-36

.

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Replace the washer motor.

Step 5. Check the wiring harness between B-134 
ETACS-ECU connector terminal Nos.12, 9 to A-35 
washer motor connector terminal No.1, 2.

NOTE: 

Prior to the wiring harness inspection, check junction 
block connector B-112, and repair if necessary.

• Check the output signal line.

Q: Is the check result normal?

YES : 

Go to Step 6.

NO : 

Repair the wiring harness.

Step 6. Retest the system.
Check that the rear washer works normally.

Q: Is the check result satisfactory?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction 

P.00-13

).

NO : 

Replace the ETACS-ECU.

ELECTRIC RETRACTABLE REMOTE 
CONTROLLED DOOR MIRROR

INSPECTION PROCEDURE H-1: Electric retractable remote controlled door mirror does not work at 
all.

CAUTION

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

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 and unfolding), the door mirror 
assembly or the ETACS-ECU may be defective.

POSSIBLE CAUSES

• Malfunction of the remote controlled mirror switch

• Malfunction of the ignition switch (ACC)

• Malfunction of door mirror assembly

• Malfunction of ETACS-ECU

• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE

Step 1. Pulse check
Check the input signals below which are related to 
the electric retractable remote controlled door mirror.

OK: The M.U.T.-III sounds or the voltmeter 
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. : 

Go to Step 

2.

The ignition switch (ACC) signal is not received. : 

Refer to Inspection Procedure N-1 "The 
ignition switch (ACC) signal is not received 

P.54B-200

."

The electric remote controlled mirror switch 
(folding/unfolding switch) signal is not received. : 

Refer to Inspection Procedure N-8 "Signal is 
not received from the electric remote 
controlled mirror switch (folding/unfolding 
switch) 

P.54B-213

."

Step 2. Connectors check D-01 door mirror 
assembly (RH) connector and D-15 door mirror 
assembly (LH) connector

Q: Is the check result normal?

YES : 

Go to Step 3.

NO : 

Repair the connector.

Step 3. Check the door mirror assemblies.
Check whether the door mirror assemblies work nor-
mally (Refer to GROUP 51 

− Door Mirror 

P.51-43

).

Q: Is the check result normal? 

YES : 

Go to Step 4.

NO : 

Replace the door mirror assemblies.

Step 4. Connector check: B-134 ETACS-ECU 
connector

Q: Is the check result normal?

YES : 

Go to Step 5.

NO : 

Repair the connector.

Step 5. Voltage measurement at the B-134 
ETACS-ECU connector

(1) Remove the ETACS-ECU, and measure at the 

junction block side.

(2) Check the voltage between the B-134 

ETACS-ECU connector terminal No.1 and body 
earth.

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 7.

NO : 

Go to Step 6.

Step 6. Check the wiring harness between B-134 
ETACS-ECU connector terminal No.1 to the 
fusible link (6)

NOTE: 

Prior to the wiring harness inspection, check junction 
block connector B-108, and repair if necessary.

• Check the power supply line to the battery for 

open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

− How to 

use Troubleshooting/inspection Service 
Points 

− How to Cope with Intermittent 

Malfunction 

P.00-13

).

NO :
