Expert Insight: The Importance of Correct Software
As a technician with over two decades of experience, I’ve seen countless issues arise from generic, non-programmed modules. The Vortec engines in these late-90s GM trucks are robust, but they are highly dependent on the precise software calibrations in the PCM. A generic or junkyard module can cause persistent drivability problems that are impossible to diagnose. Our process ensures your Programmed 09355699 PCM has the exact software your truck was designed to run on, updated to the latest version from GM. This isn’t just a part; it’s a complete, reliable solution that gets the job done right the first time.
Frequently Asked Questions
What information do you need from me?
After you place your order, we require your vehicle’s 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your specific engine, transmission, and options.
Do I need to do anything after installing this PCM?
In many cases, you may need to perform a security relearn procedure (often called Passlock or Passkey) to sync the new PCM with your vehicle’s anti-theft system. This procedure can typically be done without special tools and instructions can be readily found online for your specific model. On some vehicles, a Crankshaft Variation Relearn (CASE Relearn) may also be required with a scan tool to clear a P1336 code.
How do I know if my original PCM is faulty?
Common signs include a no-start condition where the engine cranks but won’t fire, multiple unrelated error codes, erratic engine behavior like stalling or misfiring, and communication failures with a diagnostic scan tool. A professional diagnosis is always recommended, but these symptoms strongly point to a failing PCM.
Is this a brand new part?
This is a high-quality replacement component that has been thoroughly inspected and prepared to meet or exceed original equipment specifications. We load it with fresh, VIN-matched software to ensure it functions as intended.
Will this fix my vehicle’s failed emissions test?
If the failed emissions test was caused by a Check Engine Light and codes related to PCM performance or sensor circuits it controls, this Programmed 09355699 PCM is a critical step in resolving the issue. By restoring proper engine function, it allows the emissions systems to operate as designed.
