What you’re buying
- One refurbished and fully tested Engine Control Module (ECM / PCM / ECU), programmed to your VIN so it will match your vehicle.
- No core charge – you keep your old ECM.
Important – VIN required
After purchase, you must provide your vehicle VIN so we can program the module to exactly match your vehicle. The module will be programmed prior to shipment.
Warranty
- One-year replacement warranty.
Possible procedures after installation
Two procedures may be required after installing the programmed ECM:
-
Anti-theft (passlock) relearn
- If required, the vehicle may not start until the anti-theft relearn is completed.
-
Crankshaft variation (CV) relearn
- If the engine runs but the “Service Engine Soon” / check engine light illuminates, a CV relearn may be required and Code P0315 may be stored.
- A scan tool capable of performing the CV relearn is required to complete the procedure and clear related codes. If you do not have access to such a tool, a repair shop can perform the relearn and clear the codes.
- The vehicle will run normally, but the warning light and stored code will remain until the relearn is completed.
Instructions for both procedures will be included with the module.
Shipping
- We ship within one business day of payment.
- Same-day shipping available if ordered by 2:00 PM EST (Mon-Fri).
Additional note
Flashmasters does not use ACDelco Technical Delivery System (TDS) services for module programming. (ACDelco is an automotive parts brand owned by General Motors.)
