GENERAL DESCRIPTION

• Antenna and receiver are incorporated in the 

ETACS-ECU.

• ID code can be registered by using the scan tool 

MB991958 (MUT-III sub assembly).

• Transmitter is a key holder type, which incorpo-

rates lock button, unlock button, and panic but-
ton.

• The locking is answered back by two times' flash-

ing of the dome light, two times' flashing of the 
turn signal lights and one time sounding of the 
horn answerback.

• The unlocking is answered back by illuminating of 

the dome light for 15 seconds and one time flash-
ing of the turn signal lights.
