Normal Operation

WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The digital transmission range (TR) sensor is hardwired directly to the powertrain control module (PCM), which provides the instrument cluster with the transmission range data over the communication network. The instrument cluster PRNDL display is controlled by the instrument cluster, indicating the appropriate range as transmitted to the instrument cluster by the PCM. The front electronic module (FEM) and rear electronic module (REM) both control and monitor the exterior illumination. When an exterior lamp is inoperative, the FEM or REM notify the instrument cluster over the communication network and the instrument cluster illuminates the warning center message LAMP OUT.
