[Comment]When the PANIC switch is pressed, the receiver sends a PANIC signal to ETACS-ECU. Then the ECU flashes the headlights and sounds
the horns intermittently for approx. three minutes.
The headlights and horns share an operation circuit with the theft-alarm system. Because of this, if the theft-alarm system functions normally,
the
harness between the receiver and the ETACS-ECU mav be defective.
