Keyless Entry: Description and Operation

Circuit Description
The ETACS control module controls the keyless entry system. When the ETACS control module receives code signals from the transmitter the ETACS control module compares the received code signals with memorized code. If the codes agree, the ETACS control module sends signals to the door modules and turn signal lamps. According to the signals, the turn signal lamps are flashed several times and the door locks are opened.
