When the brain of your engine is compromised, you need a reliable replacement SSR 12573503 PCM that’s ready to install right out of the box.
Common Symptoms of a Failing PCM & Your Solution
If you’re experiencing any of the following, a failing PCM is the likely culprit:
- Persistent Check Engine Light: Especially for codes like P0601, P0602, or P0606 (Internal Control Module Errors).
- Engine Stalling or Misfiring: Unexplained stalling at idle or while driving.
- Poor Performance & Fuel Economy: A noticeable drop in power, acceleration, and miles per gallon.
- Erratic Transmission Shifting: Harsh or delayed gear changes that aren’t related to a mechanical transmission fault.
- No-Start Condition: The engine cranks but refuses to start, even with a good battery and starter.
Replacing sensors and other components without addressing the core issue can be a costly and time-consuming process. Installing a properly programmed SSR 12573503 PCM is the most effective solution to eliminate these electronic gremlins and get your vehicle running correctly again.

Expert Insight: The “Ghost in the Machine”
“Over my 20 years in diagnostics, I’ve seen countless owners spend hundreds, sometimes thousands, replacing perfectly good sensors, coils, and fuel pumps, all because the root cause was a failing PCM. The module can send faulty signals, making other parts appear defective. It’s the classic ‘ghost in the machine’ scenario. By starting with a correctly diagnosed and programmed PCM, you’re not just replacing a part; you’re restoring the vehicle’s central nervous system and avoiding a frustrating chain of unnecessary repairs. It’s the smartest first step for complex electronic issues.”
Frequently Asked Questions
Do I need to do any additional programming?
No. We program the unit to the VIN you provide, so it’s ready for installation right out of the box. You may need to perform a simple security relearn procedure, which typically involves cycling the key in the ignition and takes only a few minutes. We include instructions for this easy process.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). You can typically find this on your dashboard (visible through the windshield), on your vehicle’s registration, or on the driver’s side door jamb sticker.
What if my original part number is different?
This PCM, part number 12573503, is also the correct replacement for several other service numbers (SERV.NO), including 12562481, 12571591, and 12573650. Please check our compatibility list or contact us if you are unsure.
Will this fix my transmission shifting problems?
In many cases, yes. The PCM controls both engine and transmission functions. Erratic shifting, slipping between gears, and failure to shift are common symptoms of a faulty PCM. However, it is essential to ensure your vehicle has been properly diagnosed, as mechanical transmission faults can cause similar symptoms.
Is this a brand new part?
This is a genuine, high-quality component that has been meticulously inspected, tested, and programmed with the latest software to meet or exceed original factory specifications. Confirming compatibility for your SSR 12573503 PCM ensures you receive a reliable, long-lasting solution.
