Tech Notes for B101D 2015 Chevrolet Silverado

Do not replace a device based only on Diagnostic Trouble Code (DTC) B101D being set in history except for the Inflatable Restraint Sensing and Diagnostic Module (SDM) and the Passenger Presence Module. If the DTC B101D is set as current, replace the appropriate device.



B101D:F0 set in the BCM after a dead battery event. The rare condition that sets B101D:F0 is an extremely dead battery case. It is NOT the cause of the dead battery, but the extremely low voltage is a trigger that causes this DTC to be set. If DTC B101D:F0 is set current in the Body Control Module (BCM), clear the codes. If DTC B101D:F0 clears with no other symptoms, DO NOT replace the BCM.

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.
