The cost to diagnose the B0061 MERCURY 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 Belt Tension Sensor (BTS) operates in conjunction with the Occupant Classification System (OCS). The Occupant Classification System (OCS) interprets a variable voltage signal provided by the Belt Tension Sensor (BTS) to identify the possible presence of a child safety seat in the front passenger seat. The voltage output of the Belt Tension Sensor (BTS) is proportional to the amount of tension applied to the sensor by the belt: no belt tension causes a low voltage (approximately 0.95 volt) to be output, and high belt tension causes a high voltage (approximately 3.8 volts) to be returned to the Occupant Classification System Module (OCSM).
