Code B1247 Mercury Description

The Steering Column Control Module (SCCM) monitors the multifunction switch position. When the multifunction switch is in the left or right TURN position, the SCCM sends a turn signal switch_status message over the communication network to the Body Control Module (BCM) indicating a request for the left or right turn signal. When the BCM receives a request for a turn signal, the BCM supplies on/off voltage to the appropriate turn lamps.
The timed on/off cycle for turn lamps is determined by the BCM and is set to flash approximately 80 times per minute if both the front and rear turn signal lamps operate correctly. If an individual turn signal lamp is inoperative, the BCM fast flashes the remaining turn lamp approximately 160 times per minute to indicate a bulb outage to the driver. The OBDII sets when the BCM detects the front, rear or exterior mirror turn lamp output is not to factory specifications.
