2024-2025 Tesla Cybertruck Airbag Module: The Critical 'Crash Data' Problem
This is the Supplemental Restraint System (SRS) control module, not a Body Control Module, and buying a used one requires a mandatory data reset to function.
- This part is the SRS Restraint Control Module (RCM), not a Body Control Module (BCM).
- A used module that has been in a vehicle during a collision will have permanent 'crash data' and is non-functional.
- The module MUST be sent to a third-party reset service to clear crash data before it can be installed and used.
- Tesla dealers will NOT install a used SRS module or reset a locked one; they will only replace it with a new part.
Identifying the Cybertruck's Airbag Control Module
While sometimes confused with a Body Control Module (BCM), this part is exclusively dedicated to the airbag system. The correct term is the Restraint Control Module (RCM) or Supplemental Restraint System (SRS) module. It is a critical safety component responsible for deploying the airbags and seatbelt pretensioners during an accident. The primary OEM part number for the 2024-2025 Cybertruck is 1872985-00-A, manufactured by Bosch.
Warning: This is a safety-critical part. Tesla's official service documentation explicitly warns against installing used SRS components from another vehicle. This is primarily because a used module will contain the VIN and configuration of the donor vehicle and, more importantly, will have stored crash data if it came from a vehicle involved in an accident.
Symptoms of a Faulty Airbag Module
The most common and obvious symptom of a malfunctioning or locked RCM is a persistent airbag warning light on the vehicle's touchscreen display. This light indicates that the SRS system is inactive and will not deploy the airbags in a crash. Diagnostic scans may reveal specific trouble codes related to internal module faults or communication errors.
The 'Crash Data' Problem: Why You Can't Just Swap a Used Module
After any collision that triggers airbag or seatbelt pretensioner deployment, the RCM permanently stores crash data in its internal memory (EEPROM). This action locks the module, rendering the entire airbag system inoperative until the module is either replaced or reset. A standard diagnostic tool cannot clear this locked data.
Tesla service centers will not install a used RCM or reset one with crash data; their policy is to replace the unit with a new one. This makes third-party reset services essential for anyone purchasing a used or recycled airbag module.
Pro Tip: Before purchasing a used RCM, you must have a plan for getting it reset. Numerous independent services specialize in clearing crash data from Tesla airbag modules. This process involves reprogramming the module's memory back to its factory state, making it ready for installation without needing further programming by a dealer.
Buying a Used 2024-2025 Cybertruck Airbag Module
When buying a used RCM, the most critical factor is not mileage or physical condition (though you should avoid any units with physical damage or corrosion), but rather the understanding that it must be sent to a specialist for crash data clearing before installation. A used module that has not been reset is non-functional.
- Verify the Part Number: Ensure the part number is 1872985-00-A to match your 2024-2025 Cybertruck.
- Inspect for Damage: Check the housing and connectors for any signs of cracks, water intrusion, or damage from being dropped. Tesla service literature warns never to use a module that has been dropped.
- Factor in Reset Costs: The price of the used module is only part of the total cost. You must add the fee for a mail-in reset service.
- Why Used OEM is the Only Option: There are no new aftermarket RCMs available for these vehicles. A used OEM module, once properly reset, is identical to a new one in function. The reset service restores the original factory programming.
Programming and Installation Requirements
Once a used module has had its crash data cleared by a reputable service, it is typically plug-and-play and will not require additional programming or coding to the vehicle's VIN. However, the installation process itself is involved and requires following specific safety protocols.
According to Tesla's service manual, replacement involves disconnecting all low-voltage power, removing the center console to access the module, and then performing post-replacement software routines using the vehicle's touchscreen Service Mode to ensure the new module communicates correctly with all sensors. While a DIY replacement is possible for an experienced mechanic, the safety-critical nature of the SRS system means professional installation is highly recommended.
Known Issues, Recalls, and TSBs
As a new vehicle, the 2024-2025 Cybertruck has had several recalls, though none directly implicate the Restraint Control Module itself. Recalls have addressed issues such as detaching exterior trim panels, accelerator pedals, and wiper motors. There are no widespread reports of premature RCM failure, but some early owners have reported issues with 'body controllers' causing no-start conditions.
Cost Comparison
| Part Type | Estimated Cost | Notes |
|---|---|---|
| New OEM (from Tesla) | $800 - $1,800+ | Price varies by location and includes the module only. Labor is additional. |
| New Aftermarket | Not Available | No aftermarket manufacturers produce this safety-critical component. |
| Used OEM (Recycled) | $90 - $200 | Requires an additional fee for a crash data reset service. |
| Crash Data Reset Service | $50 - $150 | Mail-in service to clear crash data from a locked module. |
| Shop Labor for Replacement | $150 - $250 | Estimated 1-2 hours of labor. Tesla's flat rate time is approximately 0.42 hours for the module itself, but this does not include removing interior components like the center console. |
Frequently Asked Questions (FAQ)
Do I need to program a used Cybertruck airbag module?
No, provided you have it sent to a reset service first. These services wipe the crash data and restore the module to its original factory state, making it plug-and-play without needing dealer programming.
Can a Tesla Service Center install a used airbag module I bought?
No. Tesla's official policy is to only install new, genuine Tesla parts for SRS components. They will not install a used part from any source, nor will they reset a module with crash data.
Where is the airbag module located on the 2024-2025 Cybertruck?
While specific Cybertruck documentation is sparse, Tesla vehicles typically place the RCM under the center console, between the front seats. Accessing it requires removing the center console assembly.
What OBD-II codes are related to a bad airbag module?
While Tesla uses a proprietary diagnostic system, common generic SRS codes start with a 'B' (for Body). Codes like B1211 (Airbag Control Unit Internal Fault) or B1231 (Airbag Control Module Communication Error) could indicate a problem. After an accident, codes indicating 'Crash Data Stored' like B1650 will be present and cannot be cleared with a standard scanner.
