Using a feature called Inadvertent Power Control, the body
control module (BCM) supplies power to all of the following components:
| • | The glove compartment lamp |
| • | The rear compartment lamp |
The left front door ajar switch turns ON the interior lamps through
the BCM by grounding CKT 394. When the left front door is open, the
switch is closed. This condition provides a ground and a door open input
to the BCM. The BCM then grounds the following lamps in order to turn the
lamps ON:
The right front door ajar switch and the rear door ajar switches turn
ON the interior lamps by grounding CKT 395 from the BCM. When the ignition
key is removed from the lock cylinder, the interior lamps remain ON for
approximately 10 seconds.
The BCM provides an interior lamps-ON delay after a door is opened.
The lamps remain ON for approximately 10 seconds or until the ignition
switch is turned to the ON position.
The dome lamp OFF-DOOR-ON switch controls the dome lamp. When the switch
is in the OFF position, the dome lamp remains OFF. When the switch is in the
DOOR position, the dome lamp lights when a door is opened. When the switch
is in the ON position or the dimmer switch is moved to the dome lamp position,
the dome lamp lights without turning on the courtesy lamps. The rear view
mirror reading lamps are controlled by the following items/actions:
| • | The rear view mirror reading lamps switch |
| • | Moving the dimmer switch to the dome lamp position. |
When a door unlock signal or a trunk release signal is received by the
remote control door lock receiver, the remote control door lock receiver signals
the BCM to turn ON the interior lamps through the use of a class 2
serial data link.
Voltage is applied at all times through the INT LPS fuse to the BCM.
The BCM then applies voltage at all times to the inadvertent power control.
Voltage is applied at all times through the AUX PWR/CIGAR fuse to the
auxiliary power outlet and the cigar lighter.
Battery Run Down Protection
The inadvertent power control output of the BCM applies
voltage to the following components:
| • | The glove compartment lamp |
| • | The rear compartment lamp |
When the ignition switch is in the OFF position, the output timer turns
off the power to all of the above lamps after 18-22 minutes.
Reset the inadvertent power control output by performing one of the
following actions:
| • | Turn the ignition switch to the RUN position. |
| • | Turn OFF any interior lamps that may be ON. |
| • | Press the power door lock switch. |
| • | Press the decklid release switch. |
