Frequently Asked Questions
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship the module until we receive this information.
Will I need to do anything after I install it?
In most cases, this is a plug-and-play installation. However, some vehicles may require a simple security or Crankshaft Position Sensor (CASE) relearn procedure, which can be done with a capable scan tool. This is a standard step for this type of repair.
Is this a new part?
This is a professionally prepared, tested, and guaranteed functional component, programmed with the latest software for your vehicle. It is a direct replacement for the original factory unit.
What if my original part number is different from 12653246?
This ECM is also a direct replacement for service numbers 12635043 and 12639471. As long as your vehicle is a 2010-2014 GM truck/van with the 4.3L engine, this module will be programmed to work perfectly.
Where is the ECM located on my truck?
On the 2010-2013 Silverado and Sierra 1500, the ECM is located in the engine bay, on the driver’s side, underneath the battery tray. On Express and Savana vans, it is typically on the driver’s side rear of the engine compartment.
