STEP 4. Check the wiring harness between trunk lid latch
assembly connector F-05 (terminal 2) and ETACS-ECU
connector C-217 (terminal 37).
NOTE: Also check intermediate connector C-28 for loose, cor-
roded, or damaged terminals, or terminals pushed back in the
connector. If intermediate connector C-28 is damaged, repair or
replace the connector as described in GROUP 00E, Harness
Connector Inspection P.00E-2.
Q: Is the wiring harness between trunk lid latch assembly
connector F-05 (terminal 2) and ETACS-ECU connector
C-217 (terminal 37) in good condition?
YES : Replace the ETACS-ECU. If the functions described
in "CIRCUIT OPERATION" work normally, the input
signal from the trunk lid latch assembly should be
normal.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. If the
functions described in "CIRCUIT OPERATION" work
normally, the input signal from the trunk lid latch
assembly should be normal.

SIMPLIFIED WIRING SYSTEM (SWS)54B-472
INSPECTION PROCEDURE N-8: Transmitter (integrated into key): ETACS-ECU does not receive any
signal from the lock, unlock, trunk or panic switch.
Whenever the ECU is replaced, ensure that the input signal
circuit is normal.
.
COMMENTS ON TROUBLE SYMPTOM
Refer to circuit diagrams GROUP-90
Refer to configuration diagrams GROUP-80
Input signal from the keyless entry transmitter is used to oper-
ate the keyless entry system. If the signal is abnormal, the key-
less entry system will not work normally.
.
POSSIBLE CAUSES
Malfunction of the ETACS-ECU
Malfunction of the keyless entry transmitter
Defective battery of the keyless entry transmitter
1. Lock switch
2. Unlock switch
3. Trunk switch
4. Panic switch
5. Indicator lamp

DIAGNOSTIC PROCEDURE
Step 1. Pulse check
Check whether the ETACS-ECU receives signal from a trans-
mitter or not. For this check, you should use the 4-button-type
transmitter (integrated with a key), which has already been reg-
istered.
NOTE: For how to register the keyless entry transmitter
encrypted code, refer to GROUP 42
On-vehicle Service
P.42-73.
OK: The MUT-III sounds or the voltmeter needle fluctu-
ates.
Q: Is the check result normal?
YES : Go to Step 2.
NO : Go to Step 4.
Step 2. Check the transmitter battery.
Refer to GROUP 42
Keyless entry system P.42-70.
Q: Is the check result normal?
YES : Go to Step 3.
NO : Replace the keyless entry key integrated transmitter
battery.
Step 3. 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 keyless entry
transmitter.
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.00-14).
NO : Replace the keyless entry transmitter.
Step 4. Retest the system.
Check that each signal is received from the keyless entry key
integrated transmitter.
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.00-14).
NO : Replace the ETACS-ECU. System switch Check condition
