What happened when owners saw B101D?

10 of the 11 reports, spread across the models above, as the owners wrote them. NHTSA removes names and VINs; long reports are trimmed. CarHooq has not verified individual claims.

After my car battery was professionally replaced my airbag light came on. GM dealer service got a code of B101D requiring the airbag control module to be replaced. There are no new compatible modules available in the US. Two GM dealers advised getting a used module that had not been in an airbag deployment. Upon obtaining a compatible module the dealer is now getting a code of B3902, this code indicates that the environment identifier of the module does not match the vehicle and prohibits further programming permitting the airbags to function properly. So GM has intentionally prohibited compatible modules from salvage cars and they are no longer making new modules for my car. How is this…

I have a 2016 Chevy volt. It had to be towed to a Chevy dealership because it will not drive. The BECM module has failed, as is apparently the case with so many volt owners. GM, as a result of lawsuits about this car, extended the warrantee to fix the issue, but my vin number is not included in the case. The gar is a brick, and there is no way to fix it now. GM doen't even replace these batteries any more, and most often just buys back the bad vehicles. I still owe 9k on this car and it is useless now. I need help. These are the codes is is throwing.

I owned a 2019 GMC Acadia Denali with surround vision system (rear camera). In December 2023, my rear camera went out and almost caused me to hit someone while backing up. I don't totally depend on the rear camera when backing, but this time when I turned around to look if anything was behind me I didn't see no one. I took my vehicle to the dealer to get it checked out and to repair it. They found that the vision process module was bad. The technician found that the vpm had internal malfunction and corrosion due to water intrusion damaging vpm completely. found code B101D for internal failure and not responding to any programming or commands. Replaced vision processing module at a cost of…

B101D: questions drivers ask

What does code B101D mean?

B101D is a manufacturer-specific body code (body: airbags, seats, lighting, climate and comfort electronics), so its exact definition depends on the carmaker and is not in the generic OBD-II list. 11 owners reported it to NHTSA, most often for the Chevrolet Malibu (6), Chevrolet Silverado (2), Chevrolet Impala (1); their reports describe what happened.

Which cars get code B101D most often?

In NHTSA owner complaints, B101D is mentioned most for the Chevrolet Malibu (6), Chevrolet Silverado (2), Chevrolet Impala (1), across 6 models and model years 2012 to 2019. Popular models collect more reports because more of them are on the road.

Is there a recall for code B101D?

No NHTSA recall text names B101D directly. 8 recalls on the cars that report this code concern the same component owners name most (Air Bags); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.

What should I do if my car shows B101D?

Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
