Guided Installation to Restore Peak Performance
Replacing the PCM is a manageable job for a DIYer with basic hand tools. Follow these steps for a confident, successful installation. Always prioritize safety.
- Safety First: Begin by disconnecting the negative terminal on your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most of these 1997 GM trucks and vans, the PCM is located in the engine compartment, typically on the driver’s side near the battery or firewall.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that may need to be gently pried up. Once disconnected, unbolt the old module from its mounting bracket.
- Install the New PCM: Mount your new, pre-programmed 1997 Savana 3500 PCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- Reconnect and Start: Reconnect the negative battery terminal. Your vehicle may require a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Start the engine and enjoy a restored ride!
An Expert’s Diagnostic Tip
Before you’re certain the PCM is the culprit, take a moment to inspect your battery terminals and the main engine ground wires. A loose or corroded connection can mimic PCM failure by causing low voltage and erratic behavior. Cleaning these connections is a simple, no-cost step that has saved many technicians hours of diagnostic time. A healthy electrical foundation is crucial for any computer to operate correctly.
