B1D6D Description


The seat track position sensor is a Hall Effect-type sensor. This sensor consists of a Hall Effect Integrated Circuit (IC) chip encased in potting material within a cavity of the molded plastic sensor housing. The seat track position sensor is designed to provide a seat position data input to the Occupant Classification Module (OCM) indicating whether the driver front seat is in a forward or rearward position. The OCM sends electronic seat position messages to the Occupant Restraint Controller (ORC) over the Controller Area Network (CAN) data bus. The ORC uses this data as an additional logic input for use in determining the appropriate deployment force to be used when deploying the multistage front airbags. The seat track position sensor cannot be adjusted or repaired and, if faulty or damaged, the entire sensor must be replaced. The Diagnostic Trouble Code (DTC) will set when the Memory Seat Module (MSMD) detects the switch engaged in an active position for over 50 seconds. If the sensor voltage is not within a specified range this DTC will set. This DTC will only set when the seat switch is moved in the same direction three consecutive times.
