Code B0080 Buick Description

The seat position sensor is used to determine the proximity of the front driver or passenger seat position with respect to the front air bag. There are two states of seat position, forward and rearward. The seat position sensor interfaces with the Inflatable Restraint Sensing and Diagnostic Module (SDM) and allows the inflatable restraint sensing and diagnostic module to disable stage 2 of the air bag for a front seat that is forward of the forward/rearward point in seat track. The seat position sensor provides two current ranges, one range for the forward seat position and one for the rearward seat position. When the Inflatable Restraint Sensing and Diagnostic Module receives input from a seat position sensor that the seat is rearward, and the inflatable restraint sensing and diagnostic module will not disable stage 2 deployment. When the seat is forward, the Inflatable Restraint Sensing and Diagnostic Module will disable stage 2 deployment. The inflatable restraint sensing and diagnostic module monitors the seat position sensor circuit and if a fault is detected, the Inflatable Restraint Sensing and Diagnostic Module will set Diagnostic Trouble Code (DTC) B0080 and disable stage 2 frontal deployment.

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.
