4 - Engine Hood Courtesy Switch Circuit
CIRCUIT DESCRIPTIONWhen all the alarming functions do not operate and when the setting is possible even if the conditions are not met, the miscarriage of the alarming condition that the ON signal from the courtesy light switch of the luggage door cannot be recognized by the theft deterrent ECU (because of short-circuit) causes them. Also, when the automatic alarm works without any operation, it is because the courtesy light switch of each door, hood or luggage door is turned on by short-circuit.
