Cruise Indicator 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.
The cruise indicator lamp is controlled by the ECM.
When the ASCD system is turned on, the ECM signals the combination meter (unified meter control unit) via the CAN lines and ground is provided to the cruise indicator lamp.
When power and ground are supplied, the cruise indicator lamp illuminates.
