Tech Notes for B101D Buick
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.
