Restore Peak Performance to Your GM Vehicle

Is your 2003 GMC Savana or other compatible GM truck acting up? Intermittent stalling, a persistent check engine light, or a frustrating no-start condition can often point directly to a failing Powertrain Control Module (PCM). As the central computer of your vehicle, the PCM manages everything from fuel mixture and ignition timing to transmission shifting. When it falters, the symptoms can be unpredictable and difficult to diagnose. This replacement module, part number 89017733, is the definitive solution to get your vehicle running reliably again.

Forget the hassle and expense of a dealership visit. We take the guesswork out of the repair by pre-programming this module specifically for your vehicle. Simply provide your Vehicle Identification Number (VIN) after purchase, and our technicians will flash the unit with the latest, most stable software updates directly from GM. This ensures optimal performance and compatibility right out of the box. This is the same process I’ve used in my shop for years to guarantee a successful repair on the first try, saving my customers time and money.

Is Your Vehicle Showing These Symptoms?

  • ✔ Check Engine Light is on with communication-related codes (e.g., P0601, P0606).
  • ✔ The engine cranks but refuses to start.
  • ✔ Unexplained drops in fuel economy.
  • ✔ Harsh or erratic automatic transmission shifting.
  • ✔ Intermittent stalling or hesitation during acceleration.
  • ✔ Failure to pass an emissions inspection.

A Technician’s Notebook: The Work Van That Wouldn’t Work

A 2003 Express van came into my bay with a complaint that stumped two other shops: it would randomly stall at idle, but only after it was fully warmed up. There were no consistent trouble codes, just a history of random communication faults. After checking all the usual suspects—fuel pressure, grounds, sensor data—I focused on the PCM. On these vans, the PCM is tucked in the engine bay where it endures intense heat cycles. Over 15+ years, these cycles can cause microscopic cracks in the circuit board. By monitoring live data, I finally caught the processor voltage drop just before a stall. Swapping in a VIN-programmed PCM like this one solved the issue permanently. The owner was back to work the next day, problem-free.

A Straightforward Guide to Installation

  1. ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery.
  2. ✔ Locate the PCM: On most Savana/Express vans, it’s in the LH rear of the engine compartment. On trucks, it’s often under the battery tray.
  3. ✔ Disconnect Connectors: Carefully unclip and remove the wiring harness connectors from the old module. Inspect them for any corrosion or damage.
  4. ✔ Remove Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
  5. ✔ Install New Module: Mount your new, pre-programmed PCM and securely re-attach the wiring harness connectors.
  6. ✔ Reconnect Battery: Re-attach the negative battery terminal.
  7. ✔ Perform Security/CASE Relearn: You will need a capable scan tool to perform the Crankshaft Variation (CASE) relearn procedure. This is a critical step to prevent a P1336 trouble code and ensure proper engine operation. Most local shops can perform this service for a small fee if you don’t have the tool.

Why Choose a Pre-Programmed Module?

Getting a reliable 2003 Savana 1500 PCM is about more than just the part; it’s about the software. A used module from a salvage yard will have the incorrect VIN and software, leading to a no-start condition and a mandatory trip to the dealer for expensive programming. Our service handles this critical step for you. We load your VIN and the latest GM-approved calibrations, making the installation process as simple as possible for both DIY enthusiasts and professional technicians.

Frequently Asked Questions

Do I need to do any programming myself?

No. This module arrives at your door pre-programmed with your vehicle’s VIN and the newest GM software. The only remaining step is the CASE relearn, which requires a scan tool.

What is a CASE relearn?

The Crankshaft Variation (CASE) relearn is a process that allows the new PCM to learn the position of the crankshaft reluctor wheel. It is required after replacing the PCM or crankshaft sensor to ensure accurate misfire detection and prevent trouble codes.

Is this part difficult to install?

The physical replacement is straightforward for anyone with basic mechanical skills. It involves disconnecting the battery, unplugging a few connectors, and unbolting the module. The only specialized step is the electronic CASE relearn after installation.

Will this fix my vehicle’s specific problem?

This PCM is a direct solution for failures within the module itself, which cause a wide range of symptoms. While it resolves many common issues, always ensure your vehicle has been properly diagnosed. A faulty sensor or wiring problem can sometimes mimic PCM failure.

What information do you need from me?

After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
