Normal Operation - Vehicles Equipped With IVD

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.

Each stoplamp is supplied battery voltage independently. The stoplamp ground circuits are independently controlled by the rear electronic module (REM). When the brake pedal is pressed, the BPP switch allows voltage to flow through circuit 29S-CF1 (OG/YE) to the IVD module. The IVD module then sends voltage through circuit 29S-CF2 (OG/BU), which is spliced to carry the voltage to the powertrain control module (PCM) and the rear electronic module (REM). Voltage to the REM (from the IVD module) after the splice is carried through circuit 29S-DK30 (OG). When the REM receives voltage from the IVD module, the REM grounds circuits 31S-LG6 (BK/YE) (high-mounted stoplamp), 31S-LG14 (BK/OG) (LH stoplamp) and 31S-LG21 (BK/GN) (RH stoplamp) to illuminate the stoplamps. The electric parking brake can also trigger the stoplamps by communicating to the REM (via the SCP link) that the parking brake has been actuated while the vehicle is moving.
