Automatic Control Function

The GM provides 12 volts (linear application providing soft on feature) to the interior lighting circuit when the one of the following input signal statuses change:

• Interior light switch
• Door contact hall sensor active (door opened)
• An Unlock request from the driver's door key lock hall sensors are received. This only occurs if the ignition switch is off.
• An Unlock request is from the FZV keyless entry system is received via the K bus. This only occurs if the ignition switch is off as well.
• The ignition switch is switched off (within 32 seconds) and the vehicle exterior lights (LCM) have been on for a minimum of 2 minutes prior. This information is provided to the GM via the K bus.
• Active crash signal from the MRS III control module.
• Lock button of FZV key is pressed with the vehicle is already locked (interior search function).

  The GM gradually reduces the full 12 volt power supply (linear reduction providing soft off) until the lights are off when the following input signal statuses change:

• Interior light switch
• Immediately after the ignition switch is turned to KL R with the driver's door hall sensor door contact closed.
• When the vehicle is locked (single or double) with the door contacts closed.
• When the vehicle door contacts are closed. The lights remain on for 20 seconds and then go to soft off.
• After the interior search function is activated, the lights will automatically turn off (soft off) after 8 seconds.
• After 16 minutes with a door contact active (open door) and the key off, the lights are switched off (consumer cutoff function).
