Keyless Entry: Description and Operation

CIRCUIT DESCRIPTION

The ETACM controls the keyless entry & burglar alarm system. When the ETACM receives code signals from the transmitter, the ETACM compares the received code signals with memorized code. If the codes are aligned, the ETACM 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.
