Tesla RCM Replacement & Post-Crash Reset: What to Check

Replacing a Tesla RCM, completing its post-replacement tasks and clearing post-crash load shedding are separate operations. A car powering up or a routine reporting success does not establish that collision repairs are complete. First identify the vehicle, what deployed and the applicable Tesla repair procedure.
The RCM is the restraint control module. This guide helps owners understand a repair quote and helps collision technicians find the correct documentation. It is not a substitute for the vehicle-specific SRS procedure. Sources checked October 17, 2026.
Which problem are you trying to resolve?
| Situation | What it means for the repair |
|---|---|
| Airbags or belt pretensioners deployed | Start with the required SRS replacements and inspections. |
| Replacement RCM fitted, setup incomplete | Follow the correct model-specific commissioning procedure. |
| “Post-crash load shed” condition | Check the separate power-management routine; establish safety before re-energizing. |
| Airbag warning without known deployment | Record and diagnose the exact fault. A warning alone does not identify a failed RCM. |
| Vehicle starts after a reset | Complete the repair and handoff checks. Starting is only one observation. |
Does the RCM need replacement after every collision?
Do not use visible airbag deployment as the only decision point. Tesla's 2025+ Model Y SRS inspection document includes the RCM in the replacement list for airbag or seat-belt pretensioner deployment; it also lists replacement after pedestrian hood-actuator deployment on equipped vehicles. It specifies other replacements and inspections according to the event, including belts, buckles, wiring and associated components.
The same document calls for a replacement pyrotechnic battery disconnect fuse after airbag deployment; for pretensioner-only deployment, its fuse requirement depends on whether the fuse blew. This is an example of why a “replace the RCM and clear everything” quote can miss required work. Use the complete list for the exact vehicle, not this example as a universal parts list. Tesla: SRS inspection and component replacement — 2025+ Model Y.
For a collision with no known deployment, establish the damage and diagnostic findings before deciding which components need replacement. Do not infer a deployment solely from a seller's description, a warning lamp or a car that will not start.
A mail-in crash-data clearing service is not evidence that the applicable Tesla replacement requirement has been satisfied. Ask the repairer to identify the procedure and document the replacement parts.
What “Clear Post Crash Load Shed” actually does
Tesla's Service Mode guide describes a vehicle-controller routine that clears collision-related load shedding. Its purpose is to restore electrical-system operation after the vehicle has been established as safe to re-energize. It is not an airbag repair or a substitute for required restraint-component replacement.
The published guide is based on software 2024.2.7 and shows different low-voltage panels for Model 3/Y and 2021+ Model S/X. Current menus and availability may differ. A missing button does not justify trying a similarly named action. Tesla: Service Mode guide, Low Voltage section.
If the car remains unable to power up, keep the exact alert and routine result in the repair record. Do not repeatedly clear collision conditions as a diagnostic shortcut. The pyrofuse overview explains the separate battery-disconnect component; it should not be bridged to make the car run.
Toolbox or Service Mode? Follow the correct procedure
There is no single menu sequence for every Tesla. The linked procedures below illustrate actual differences. They are reference points, not interchangeable instructions or a complete workshop procedure.
Model 3: heat-pump and non-heat-pump examples
Both linked Model 3 procedures specify a software reinstall, then Service Mode Plus and the RCM post-replacement tasks. They also distinguish headlight-leveling systems: a virtual pitch sensor requires a subsequent headlight adjustment, while the ride-height-sensor branch finishes differently.
Use the procedure matching the vehicle's equipment: Model 3 with heat pump or Model 3 without heat pump. A touchscreen-based task does not mean ordinary owner Service Mode access is sufficient.
2025+ Model Y example
This procedure requires RCM disarming before removal. After installing the correct replacement, it specifies a software reinstall, gateway unlock and RCM post-replacement tasks, followed by headlight adjustment and verification of vehicle operation. It also identifies an access-method difference for certain APAC production dates. Tesla: 2025+ Model Y RCM replacement.
Legacy Model X example
The legacy Model X manual specifies a CAN ECU software reinstall, a Toolbox connection, gateway unlock and an RCM service-task routine. That routine has a firmware prerequisite of 2024.8 or later. Its completion checks include the airbag indicator behavior and falcon-door calibration. Access involves the front-seat inner riser and an HVAC duct, so “remove the center console on every Tesla” is incorrect. Tesla: legacy Model X RCM replacement.
For other generations, Model S or a different regional configuration, select the matching manual at Tesla Service. Do not borrow a torque value, isolation delay or routine from another model. Check current diagnostic access requirements before booking the job; old subscription-price estimates are not a reliable repair budget.
What to put in the repair plan
Before authorizing parts or software work, ask the shop to record:
- Vehicle identity: VIN, build date, market, installed software and relevant equipment.
- Collision evidence: deployed devices, occupied seats where known, inspection findings and the original diagnostic report.
- Procedure selection: the applicable replacement policy, RCM replacement procedure and linked safety/setup instructions.
- Parts: correct part numbers, required associated components and replacement fasteners, with traceable sourcing.
- Completion scope: software/setup work, any required adjustments or calibrations, and the checks used to confirm the repair.
This is a practical job-record checklist. It does not replace Tesla's damage-specific inspection list, and it does not imply that every collision needs the same parts.
For owners comparing estimates, ask whether the price covers diagnosis, required associated restraint work, commissioning and final verification. A low price for “crash reset” may describe only one operation.
What to verify before handoff
The useful result is a documented repair, not merely a cleared screen:
- Required physical work is complete. Account for the components and inspections in the selected collision procedure.
- The correct setup tasks completed. Save the routine name, result and any failure details. “We cleared the codes” does not identify what was done.
- Remaining warnings have an explanation. Review current alerts and investigate unresolved restraint faults. Do not assume every fault is a loose connector.
- Vehicle-specific finishing checks are complete. Include the adjustments, calibrations and indicator checks called for by the applicable procedure.
- The customer receives the record. List parts replaced, work performed and any outstanding issue clearly.
Service Mode alert guidance helps distinguish current and recent alerts. An empty alert list alone cannot verify an unseen mechanical repair or prove that the correct parts were fitted.
If the shop cannot complete the prescribed setup or verification, refer that portion to a qualified Tesla collision specialist before handoff. Diagnostic-tool access by itself is not SRS training.
