Theory of Operation

The (E12) Panel Lamps Driver Circuit, (M24) Courtesy Lamps Driver Circuit, and the (M27) Reading/Rail Lamps Driver Circuit all share an internal voltage feed from the Cluster. The (A909) Fused B(+) circuit supplies the voltage for these circuits. A short to ground on the (E12), (M24), or (M27) circuits, or the components they feed, will cause the entire interior lighting system to fail.
