Circuit 8-BA25 (WH/RD)
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 generator monitor (GEN MON) communicates the generator load and error conditions to the PCM. The PCM sends a signal to the instrument cluster using the Standard Corporate Protocol (SCP) bus to turn on the charging system warning indicator if there is an error condition.
