We load the correct GM-certified calibration file, so when you install our 2003 GMC Safari PCM 12576869, the vehicle’s systems communicate correctly, avoiding the ‘no-start’ surprises and communication errors common with un-programmed modules.

Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM arrives at your door fully programmed to the VIN you provide. The only thing you may need to do on certain GM vehicles is a simple security relearn procedure, which takes about 30 minutes and requires only your ignition key. We include instructions for this process.
Where is the PCM located on my 2003 GMC Safari?
On the 2003 GMC Safari and Chevrolet Astro vans, the Electronic Control Module (PCM) is located in the engine compartment on the driver’s side, near the battery.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
Will this fix my specific check engine light code?
This module will correct any codes related to an internal failure of the PCM itself, such as P0601 through P0606. If your codes are for sensors or other components, you must repair those issues first. A faulty PCM can sometimes cause false sensor codes, but it’s crucial to ensure the rest of your system is in good working order.
What if my original module has a different service number?
This part, 2003 GMC Safari PCM 12576869, is compatible with a wide range of service numbers listed in the product details. As long as your vehicle is listed and your original service number is on our compatibility list, this module will work perfectly once programmed to your VIN.
