Restore Your Van’s Heartbeat and Get Back on the Road
Is your trusty GMC Savana letting you down? If you’re dealing with frustrating issues like unpredictable stalling, poor fuel mileage, or a persistent check engine light that just won’t go away, the problem might be deeper than a simple sensor. The Powertrain Control Module (PCM) is the brain of your vehicle, and when it starts to fail, it can cause a cascade of confusing and costly problems. This isn’t just an inconvenience; it’s a hit to your productivity and peace of mind. We’re here to provide the definitive solution: a reliable, VIN-programmed PCM that gets you back in control.
Warning Signs and How to Overcome Them
A failing PCM can manifest in numerous ways. This replacement module is designed to resolve these common headaches, restoring the smooth, dependable operation you expect from your van. Look out for these symptoms:
- ✔ Sudden and unexplained engine stalling or rough idling.
- ✔ A noticeable decrease in fuel economy, costing you money at the pump.
- ✔ The Check Engine Light is on with Diagnostic Trouble Codes (DTCs) like P0601, P0604, or P0605.
- ✔ Harsh, erratic, or delayed transmission shifting.
- ✔ A frustrating no-start condition, even with a good battery and starter.
- ✔ Communication errors with diagnostic scan tools.
A Mechanic’s Pro-Tip
Before you condemn your PCM, double-check your battery terminals and primary ground connections. A loose or corroded ground wire can mimic PCM failure by causing voltage drops and erratic behavior. A few minutes with a wrench and a wire brush can sometimes save you a lot of diagnostic time. If the connections are clean and tight and the problems persist, the PCM is the most likely culprit.
Guided Installation for a Confident Fix
Replacing your 1998 Savana 3500 PCM is a straightforward job you can tackle with basic hand tools. Our module arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership programming. Just follow these steps for a successful installation:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Old Module: On most of these GM vans and trucks, the PCM is located in the engine compartment, typically on the driver’s side fender well or near the battery.
- Disconnect the Harnesses: Carefully unplug the electrical connectors from the old PCM. There are usually release tabs that need to be depressed. Inspect the connectors for any corrosion or damaged pins.
- Remove the Old Unit: Unbolt the old PCM from its mounting bracket. It’s usually held in place by a few bolts or nuts.
- Install the New PCM: Mount your new, pre-programmed PCM securely onto the bracket and reconnect the electrical harnesses. Ensure they click firmly into place.
- Reconnect and Start: Reconnect the negative battery terminal. In some cases, a security relearn procedure (often called a CASE relearn or Passlock relearn) may be necessary. This can typically be done without special tools and instructions are widely available online.

Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM (indicated by codes like P0601-P0606), then yes, this replacement will resolve the issue. However, if the light is on due to a faulty sensor or other component, that separate issue will still need to be addressed.
