Normal Operation

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The Occupant Classification System Module (OCSM) monitors each Occupant Classification System (OCS) weight sensor bolt for correct calibration/weight and identification. When the OCSM detects a fault from any of the 4 sensors or if an OCS system component has been installed new, it will store a DTC in memory and send a message to the Restraints Control Module (RCM).

The RCM will store DTC B00A0:09 in memory and send a message to the Instrument Panel Cluster (IPC) to illuminate the air bag warning indicator.

DTC DESCRIPTION TABLE

DTC Description Fault Trigger Condition
  • B00A0:54 - Occupant Classification System: Missing Calibration
 When the OCSM senses a calibration from one or more weight sensor bolt(s) that is not stored in memory, a fault will be indicated. A new OCS component installed in the vehicle can set this DTC.
  • B00A0:76 - Occupant Classification System: Wrong Mounting Position
 When the OCSM senses signals from weight sensor bolt(s) that are not the correct values for their position on the seat track, a fault will be indicated. Sensors that are not connected correctly can set this DTC.
  • B00C0:49 - Passenger Seat Occupant Classification Sensor "A": Internal Electronic Failure
 The OCSM determines sensor "A" is clamped high or clamped low. When the OCSM measures sensor output to be between 4.750 volts and 4.850 volts (sensor is clamped high) or when measured sensor output voltage is between 0.250 to 0.625 volt (sensor is clamped low), a fault will be indicated. A faulted sensor, passenger seat not installed correctly or bent or binding passenger seat track can set this DTC.
  • B00C1:49 - Passenger Seat Occupant Classification Sensor "B": Internal Electronic Failure
 The OCSM determines sensor "B" is clamped high or clamped low. When the OCSM measures sensor output to be between 4.750 volts and 4.850 volts (sensor is clamped high) or when measured sensor output voltage is between 0.250 to 0.625 volt (sensor is clamped low), a fault will be indicated. A faulted sensor, passenger seat not installed correctly or bent or binding passenger seat track can set this DTC.
  • B00C2:49 - Passenger Seat Occupant Classification Sensor "C": Internal Electronic Failure
 The OCSM determines sensor "C" is clamped high or clamped low. When the OCSM measures sensor output to be between 4.750 volts and 4.850 volts (sensor is clamped high) or when measured sensor output voltage is between 0.250 to 0.625 volt (sensor is clamped low), a fault will be indicated. A faulted sensor, passenger seat not installed correctly or bent or binding passenger seat track can set this DTC.
  • B00C3:49 - Passenger Seat Occupant Classification Sensor "D": Internal Electronic Failure
 The OCSM determines sensor "D" is clamped high or clamped low. When the OCSM measures sensor output to be between 4.750 volts and 4.850 volts (sensor is clamped high) or when measured sensor output voltage is between 0.250 to 0.625 volt (sensor is clamped low), a fault will be indicated. A faulted sensor, passenger seat not installed correctly or bent or binding passenger seat track can set this DTC.
