Normal Operation

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

Under normal operation, the Dual Automatic Temperature Control (DATC) module receives battery voltage through circuit 29-FA10 (OG/GN) and ignition voltage through circuit 20-FA10 (PK/OG). A ground is provided for the DATC module through circuit 31-FA10 (BK).
