Airbag control module (ACM/SDM/RCM)
Run the part number through a reset-service site. If it comes back resettable and the car wasn't in a deployment, it's a $60 core. If the vehicle was airbag-deployed, the crash data is burned in and it's a dollar of board.
How to spot it
Small aluminium or plastic box about 3×4×1 inches with one to three yellow-locking connectors, mounted on the transmission tunnel under the centre console, under a front seat, or behind the radio. Usually marked with an orientation arrow — FRONT →.
Metal content
| Metal | Quantity | Notes |
|---|---|---|
| Gold | 0.010–0.030 g per unit | gold-flashed pins; older units have an Au/Pd/Ag thick-film hybrid |
| Silver | 0.05–0.2 g per unit |
At 4 Aug 2026 spot prices that works out to $5.70 per pound of contained metal — Gold 0.04 g = $5.22, Silver 0.25 g = $0.48. A refiner paying $3 returns about 53% of that, which is normal: refining costs money and the buyer takes a margin.
Safe removal
Working temperature: Cold
Battery negative off, then wait 10–30 minutes. SRS modules hold a backup capacitor that can still fire squibs after the battery is disconnected. Then press the CPA lock, release the latch and unplug the yellow connectors. 10 mm socket or T30.
Hazards
NEVER open, cut, heat, drill, drop, shred or sell an inflator. There is no recoverable metal in one — the initiator's gold is measured in micrograms. Deploy-in-place by a trained handler, or hand it to the OEM collection stream.
NEVER dry sweep or use compressed air on a scrapping bench. HEPA-vac or wet-wipe only.
