To diagnose the B11D8 code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
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).
