INPUT SIGNAL PROCEDURES
SMART WIRING SYSTEM (SWS) NOT USING SWS MONITOR
54B-224
DIAGNOSIS PROCEDURE
Step 1.Connector check: D-08 front door lock
actuator (RH) connector
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Repair the defective connector.
Step 2. Check the front door lock actuator (RH).
Refer to GROUP 42
− Door
Q: Is the check result normal?
YES :
Go to Step 3.
NO :
Replace the front door lock actuator (RH).
Step 3. Resistance measurement at the D-08 front
door lock actuator (RH) connector
(1) Disconnect the connector, and measure at the
wiring harness side.
(2) Resistance between D-08 front door lock actuator
(RH) connector terminal No.3 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 D-08
front door lock actuator (RH) connector terminal
No.3 to body earth D-08
NOTE:
Prior to the wiring harness inspection, check interme-
diate connector B-21, 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 from D-08 front
door lock actuator (RH) connector terminal No.1
and 2 to B-132 ETACS-ECU connector terminal
No.41 and 36.
NOTE:
Prior to the wiring harness inspection, check interme-
diate connector B-21, and repair if necessary.
• 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 driver's door lock actuator switch sig-
nal 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.
Inspection Procedure N-12: Each switch signal of the keyless entry transmitter is not received.
CAUTION
Whenever the ECU is replaced, ensure that the
input signal circuit is normal.
COMMENTS ON TROUBLE SYMPTOM
Input signal from the keyless entry transmitter is
used to operate the keyless entry system. If the sig-
nal is abnormal, the keyless entry system will not
work normally.
• Keyless entry system
• Keyless entry hazard answerback
• Multi-mode keyless entry system
POSSIBLE CAUSES
• Malfunction of the keyless entry transmitter
• Defective battery of the keyless entry transmitter
• Malfunction of the ETACS-ECU

DIAGNOSIS PROCEDURE
Step 1. Pulse check
Check whether the ETACS-ECU receives signal from
a transmitter or not. For this check, you should use
the 2-button-type transmitter (integrated with a key),
which cover screw is silver and has already been
registered.
NOTE: For how to register the keyless entry trans-
mitter encrypted code, refer to GROUP 42
−
On-vehicle Service
.
OK: The M.U.T.-III sounds or the voltmeter
needle fluctuates.
Q: Is the check result normal?
YES :
Go to Step 2.
NO :
Go to Step 4.
Step 2. Register the encrypted code, and then
retest the system.
1. Register the keyless entry transmitter again.
2. Check that each signal is received from the key-
less entry transmitter.
Q: Is the check result normal?
YES :
Accidental erasure of the encrypted code Or
the key is mismatched. Check that the
customer is an authorised person.
NO :
Go to Step 3 (including the case that key
registration is not possible).
Step 3. Replace the battery of the keyless entry
transmitter, and retest the system.
1. Replace the battery of the keyless entry transmit-
ter.
2. Check that each signal is received from the key-
less entry transmitter.
Q: Is the check result normal?
YES :
Flat battery.
NO :
Go to Step 4.
Step 4. Register the encrypted code again by
using a known good keyless entry transmitter.
Then retest the system.
1. Register a known good keyless entry transmitter
(the one which mounting screws are silver).
2. Check that each signal is received from the key-
less entry transmitter.
Q: Is the check result normal?
YES :
Replace the original keyless entry
transmitter.
NO :
Replace the ETACS-ECU (including the
case where registration is impossible).
