“Fits” 2001-03 GM Cars/Trucks – Computer 12200411 (Programmed to your VIN) – PCM / ECM
Overview
This listing is for one refurbished and tested Engine Control Module (ECM / PCM), service number 12200411, configured and programmed to your Vehicle Identification Number (VIN) so it exactly matches your vehicle.
Fitment
- Fits various 2001-2003 GM cars and trucks.
(Confirm fitment for your specific vehicle before purchase.)
Condition
- Refurbished and tested for functionality.
- No core charge – you keep your old ECM.
VIN Programming
- After purchase you must provide your VIN so we can program the ECM specifically to your vehicle prior to shipping.
Post-install Requirements
Two possible procedures may be required after installation:
- Anti-theft (passlock/PK) relearn
- If required, the vehicle will not start until this relearn is completed.
- Crankshaft variation relearn
- May be required once the vehicle is running. If needed, the Check Engine / Service Engine Soon light will illuminate and Diagnostic Trouble Code P1336 will be stored.
- A scan tool capable of performing the crankshaft variation relearn and clearing related codes is required to complete this procedure. If you do not have access to a capable scan tool, a repair shop can perform the relearn and clear the code.
- The vehicle will run normally even if the light is on, but the trouble code will remain stored until the relearn is completed and codes are cleared.
- Instructions for both relearn procedures are included with the ECM.
Warranty
- One-year replacement warranty.
Shipping
- We will ship within one business day of payment.
- Same-day shipping if ordered by 2:00 PM EST (Mon-Fri).
Important Note
- Flashmasters does not use ACDelco Technical Delivery System (TDS) services for any module services. ACDelco is an automotive parts brand owned by General Motors Company.
