The cost to diagnose the B13B3 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
The Restraints Control Module (RCM) analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the Parameter Identification (PID) is the deployment loop resistance measured by the Restraints Control Module (RCM). If the value displayed is lower or higher than the desired range, the Restraints Control Module (RCM) can set a Diagnostic Trouble Code (DTC). As the deployment loop resistance drifts farther outside the desired range, the chance for a Diagnostic Trouble Code (DTC) increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the Parameter Identification (PID) value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand Diagnostic Trouble Code (DTC) at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern.
