Step 6. Check the wiring harness between B-140
key reminder switch connector terminal No.6 to
B-133 ETACS-ECU connector terminal No.53.
• Check the input line for open circuit.
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Repair the wiring harness.
Step 7. Retest the system.
Check that the key reminder switch signal is received
normally.
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
).
NO :
Replace the ETACS-ECU.

INPUT SIGNAL PROCEDURES
SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR
54B-213
INSPECTION PROCEDURE N-8: Signal is not received from the remote controlled mirror switch
(folding/unfolding switch).
CAUTION
Whenever the ECU is replaced, ensure that the
input signal circuit is normal.
COMMENTS ON TROUBLE SYMPTOM
The electric-folding door mirrors work in accordance
with the input signal from the remote controlled mir-
ror switch. If the input signal is abnormal, the door
mirrors will not work normally.
POSSIBLE CAUSES
• Malfunction of the remote controlled mirror switch
• Malfunction of the ETACS-ECU
• Damaged harness wires and connectors

DIAGNOSIS PROCEDURE
Step 1. Connector check: B-20 remote controlled
mirror switch connector
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the defective connector.
Step 2. Check the remote controlled mirror
switch.
Refer to GROUP 51
.
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Replace the remote controlled mirror switch.
Step 3. Resistance measurement at the B-20
remote controlled mirror switch connector.
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Continuity between B-20 remote controlled mirror
switch connector terminal No.1 and body earth
OK: Continuity exists (2
Ω or less)
Q: Is the check result normal?
YES :
Go to Step 5.
NO :
Go to Step 4.

Step 4. Check the wiring harness between B-20
remote controlled mirror switch connector
terminal No.1 to body earth.
NOTE: Prior to the wiring harness inspection, check
joint connector B-25, and repair if necessary.
• Check the earth wires 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
).
NO :
Repair the wiring harness.
Step 5. Connector check: B-132 ETACS-ECU
connector
Q: Is the check result normal?
YES :
Go to Step 6.
NO :
Repair the defective connector.
Step 6. Check the wiring harness between B-20
remote controlled mirror switch connector
terminal No.4 to B-132 ETACS-ECU connector
terminal No.27.
• Check the input line for open circuit.
Q: Is the check result normal?
YES :
Go to Step 7.
NO :
Repair the wiring harness.
Step 7. Retest the system.
Check that the electric remote controlled mirror
switch signal is received normally.
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
).
NO :
Replace the ETACS-ECU.
