Ford Repair Questions? Ask a Mechanic for Answers ASAP
Thank you for asking your question on JustAnswer.
The front left and right turn signal outputs, the front hazard lamp outputs, the LH and RH turn signal mirror outputs, and the cornering lamp outputs are controlled by the FEM. The rear turn signal outputs and the rear hazard lamp outputs are controlled by the REM. The multifunction switch and the hazard switch are hardwired to the instrument cluster. When the multifunction switch is in the left or right turn position, or the hazard switch is placed in the ON position, the instrument cluster will send a command through the standard corporate protocol (SCP) network to the FEM and REM, which apply the signals to the appropriate lamps. When the instrument cluster commands a turn signal ON, the FEM additionally commands the appropriate cornering lamp, which is hard-wired to the FEM.
