The Seat Track Position Sensor (STPS) located underneath the occupant seat detects the horizontal position of the occupant seat and delivers it to the Supplemental Restraint System Control Module (SRSCM). The signal of STPS is one of the major parameters that determine the way dual output type airbag deploys. The SRSCM sets the Diagnostic Trouble Code (DTC) if it detects that the Seat Track Position Sensor is not to factory specifications.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

  • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
  • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
  • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
  • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
