Code B0081 2016 Chevrolet Silverado Description

The B0081 diagnostic trouble code (DTC) for a 2016 Chevrolet Silverado indicates a malfunction in the Passenger Presence Module (PPM). The PPM is a crucial component of the vehicle's occupant detection system, responsible for determining whether there is a passenger in the front passenger seat and activating or deactivating the airbag system accordingly. When the PPM malfunctions, it can lead to inaccurate readings or a complete failure to detect a passenger, potentially resulting in the airbag system not deploying in the event of a crash when a passenger is present.

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.
