Show original supplier description
The Flagship One ECM (Engine Control Module) is a refurbished and tested replacement for the 2001-2003 3.8L Pontiac Bonneville. This module, identified by service number 12209624, is programmed to your specific Vehicle Identification Number (VIN) to ensure compatibility and direct fitment. After installation, two procedures may be necessary. An anti-theft relearn might be required if the vehicle does not start, and a crankshaft variation relearn may be needed if the check engine or service engine soon light illuminates (indicated by trouble code P1336). Instructions for both procedures are included, though access to a compatible scan tool may be required, or a repair shop can perform these steps.
