B1310 MERCURY MeaningWhen the ignition switch is turned to the RUN position, a voltage signal is sent to the Body Control Module (BCM). The BCM then activates the run/start relay and the run/acc relay, which distribute fused voltage to various components. The run/acc relay is serviced as part of the BCM. the BCM continuously monitors the control side of the run/start relay. This Diagnostic Trouble Code (DTC) sets if the BCM detects an open or a short to ground on the control circuit. The BCM uses a Field-Effect Transistor (FET) to control the run/start relay. When this DTC sets, the control side of the run/start relay is disabled via the FET. Once the condition that caused the DTC to set is repaired, the BCM must pass a self-test in order for the DTC to clear and the system to resume normal operation.
