SIMPLIFIED WIRING SYSTEM (SWS)
54B-139
If the front passenger's door is open when it is locked with the driver's door switch
If the passenger's door or driver's door are locked
while the passenger's door is open and when the key
is still in the ignition key cylinder, approximately 0.3
second later the ETACS-ECU activates the unlock
relay output for 0.25 second to prevent the door from
being locked with the key inside the vehicle.
In addition, if locking the door was not prevented, a
re-try current is sent (an unlock relay output ON is
sent for 0.25 second up to 5 times including the first
attempt).
NOTE: The dotted line indicates that the system is
trying to turn on the unlock relay if the door cannot be
unlocked.
