Circuit Description

CIRCUIT DESCRIPTION

The ETACM controls the keyless entry and burglar alarm system. The Burglar Alarm activates when the ETACM receives abnormal input signals (for instance, hood switch signal, left/right door unlock switch signal, tail gate unlock switch signal, etc..). The hazard relay coil is energized through the ETACM and battery voltage is supplied to the turn signal lamps, and the ETACM sounds the siren.

The Keyless Entry operates when the ETACM receives code signals from the keyless entry transmitter. The ETACM compares the received code signal switch memorized code. If the codes are aligned, the ETACM sends a signal to the door modules and turn signal lamps. According to the signals, the turn signal lamps are flashed twice and the doors are opened.
