Light monitor

The warning signal sounds if the driver's door is open, the parking lights are on and the key has been removed from the ignition switch. Voltage +B from the ignition switch is connected to pin 7 on the control module. Accordingly, DICE detects +B when the car key is in the ignition switch.

If the driver's door is opened, DICE gets a message via the bus from TWICE (OPEN/CLOSED).

To enable DICE to determine what position (0-1-2) the light switch (10) is set to, the control module uses information from TWICE and its own pin connection.

TWICE (632), which operates the parking lights, puts information onto the bus (ON/OFF). ON corresponds to switch position 1. OFF corresponds to position 1 or 2.

DICE pin 39 is connected to light switch pin 10, which corresponds to position 0. DICE pin 15 is connected to light switch pin 11, which corresponds to position 2.

DICE sends information on the bus to SID (Audible signal) which generates a PING sound.

Maximum length of time for the acoustic signal is 10 minutes.
