Trunk Warning Lamp

WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

Trunk warning lamp is controlled by the BCM. When the trunk is opened, ground is supplied

to BCM terminal 19
through body grounds B7 and B19.

The BCM then signals the combination meter (unified meter control unit) via the CAN lines and ground is provided to the trunk warning lamp.

When power and ground are supplied, the trunk warning lamp illuminates.
