Lighting Warning

WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.

An acoustic warning signal will be activated if the driver's door is open, the parking lights are on, and the key is removed from the ignition. Voltage +B from the ignition switch is supplied to pin 7 on the control module. This means that DICE detects +B when the key is in the ignition switch.

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

So that DICE can safely determine in which position (0-1-2) the switch (10) is, it uses information from TWICE and its own pin connection.

The parking lights are controlled by TWICE (632) which gives information to the bus (ON/OFF). The message ON corresponds to switch position 1 and the message OFF corresponds to switch positions 1 or 2.

DICE pin 39 is connected to switch pin 5, which corresponds to position 0. DICE pin 15 is connected to switch pin 4, which corresponds to position 2.

DICE outputs information on the bus to SID (ACOUSTIC SIGNAL) and a PLING sound is generated.

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