1998 GMC SAVANA 1500 Powertrain Control Module (PCM) 09355699 – Programmed to Your VIN
Imagine your 1998 GMC Savana 1500 suddenly hesitating during acceleration or throwing check engine lights that disrupt your daily hauls. These frustrating symptoms often stem from a faulty powertrain control module, disrupting engine timing and fuel delivery. Our pre-programmed PCM, part number 09355699, arrives ready for your exact vehicle, flashed with the latest GM updates via your VIN for seamless integration. It matches compatible numbers like 16250279 and 09366810, ensuring broad fit across various GM models from that era. This direct replacement restores smooth performance, clears persistent codes, and gets you back on the road reliably. With over two decades in diagnostics, I’ve seen how a fresh PCM transforms sluggish vans into dependable workhorses, especially for those long delivery routes.

Common Issues & How This Fixes Them
Owners of 1998 GMC Savana 1500 vans frequently encounter powertrain control module failures that manifest as rough idling, poor acceleration, or failure to start. For instance, a corroded PCM might trigger diagnostic trouble codes like P0601 for internal memory faults, leading to erratic engine behavior during heavy loads. Water intrusion from engine compartment leaks often causes this, especially in vans exposed to harsh weather. Another common problem is intermittent stalling at stops, linked to faulty sensor communicationโthink P0122 for throttle position issuesโwhich disrupts fuel injection and leaves you stranded. I’ve diagnosed cases where outdated software in the original module exacerbates these, causing excessive emissions or reduced power. Replacing with our VIN-programmed PCM resolves these by recalibrating all systems with fresh GM updates, clearing codes and restoring precise control. Additionally, if you’re dealing with transmission slip codes like P0753, this module fixes solenoid communication glitches, preventing costly breakdowns. In one scenario, a delivery driver noticed surging speeds on highways; swapping the PCM stabilized everything without further tweaks. Always check for loose connections first, as they mimic module failuresโclean them with dielectric grease for prevention. This approach not only fixes immediate concerns but also prevents recurring issues, drawing from years of hands-on repairs on GM vans.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the PCM with the latest GM updates tailored to your 1998 GMC Savana 1500.
- Disconnect the battery to ensure safety and reset any stored codes before starting; locate the PCM in the left front engine compartment near the battery.
- Remove the old module by unplugging connectors and unbolting itโnote the orientation to avoid mix-ups.
- Install the new PCM in the same position, securing bolts and reconnecting all harnesses firmly.
- Reconnect the battery and perform a CASE relearn if needed: Cycle the ignition from off to run (without starting) three times, waiting 10 seconds each, to sync crankshaft position sensors.
- If the vehicle doesn’t start post-install due to security features, conduct a theft deterrent relearnโinsert key, turn to run for 10 minutes until the security light goes off, then repeat twice more for full synchronization, thanks to our specialized programming method.
