B11D8 MERCURY Description
The Battery Energy Control Module (BECM) monitors the impact notification output from the Restraint Control Module (RCM). The RCM outputs a Pulse Width Modulation (PWM) voltage on the circuit based on status. If the BECM senses the frequency is out of range, will illuminate the powertrain malfunction (wrench) warning indicator and set a Diagnostic Trouble Code (DTC).
