INPUT SIGNAL PROCEDURES
SIMPLIFIED WIRING SYSTEM (SWS)54B-473
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
