A Technician’s Insight: Many DIYers get stuck after installing a generic, non-programmed module. On these GM vehicles, the PCM is tied into the VATS or Passlock security system. An incorrect or un-programmed module will prevent the engine from starting, period. By providing us with your VIN, we handle that critical programming step for you. This Programmed 16265035 PCM arrives ready to work, saving you from a tow bill and hours of frustration.
Frequently Asked Questions
What do I need to do after I place my order?
After your purchase is complete, you must send us your vehicle’s 17-digit Vehicle Identification Number (VIN). We cannot ship your module until we have this information, as the programming is specific to your exact vehicle.
Is any additional programming required once I install it?
For the vast majority of vehicles on the compatibility list, no further action is needed. It is a true plug-and-play part. In very rare cases, a Crankshaft Variation Relearn (CASE Relearn) may be needed, which can be done with a capable scan tool, but this is uncommon.
How do I find my VIN?
Your VIN can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
What’s the difference between a PCM, ECM, and ECU?
The terms are often used interchangeably. PCM (Powertrain Control Module) typically controls both the engine and transmission. ECM (Engine Control Module) controls only the engine. For most vehicles this part fits, it functions as the PCM, making it the central computer for all powertrain operations.
Will this definitely fix my vehicle’s problem?
This module will correct any issues directly caused by a failing computer. However, it’s crucial to ensure your vehicle has been properly diagnosed. This part will not fix problems caused by faulty sensors, wiring, or mechanical components. A correct diagnosis ensures our Programmed 16265035 PCM is the right solution for you.
