Restore Peak Performance to Your GM Truck or SUV
Is your 1998-2000 Oldsmobile Bravada, Chevy S10, or GMC Jimmy suffering from frustrating, hard-to-diagnose issues? As a technician with over two decades of experience, I’ve seen countless vehicles with erratic behavior—stalling at stoplights, harsh shifting, a persistent check engine light, or a complete no-start condition. More often than not, the culprit is a failing Powertrain Control Module (PCM), the electronic brain of your vehicle.
This isn’t just a replacement part; it’s a direct solution. We are providing a high-quality Powertrain Control Module, part number 218-11787, that arrives at your doorstep programmed and ready to install. We take your vehicle’s unique VIN and flash the module with the latest factory software from GM. This critical step ensures all engine and transmission parameters are perfectly calibrated for your specific vehicle, eliminating the need for an expensive trip to the dealership for programming.
Case Study: A Tricky Diagnosis
I recall a 1999 GMC Envoy that was brought to my shop. The owner had already replaced the fuel pump and ignition coil trying to chase down an intermittent stalling problem. The codes were inconsistent. After checking all the wiring and grounds—a common issue on these platforms—my diagnostics pointed to an internal fault in the PCM. We installed a VIN-programmed module, just like this one. The vehicle started instantly, idled smoothly, and the problem never returned. This isn’t just about replacing a part; it’s about providing a definitive, long-lasting repair.
Why a VIN-Programmed Module is Essential
The 1998-2000 Bravada PCM is not a one-size-fits-all component. It manages everything from fuel injection and spark timing to transmission shift points and emissions controls. Without the correct software matched to your VIN, your vehicle may not run correctly, or at all. Our process ensures seamless integration, restoring the original performance and reliability you expect from your truck or SUV.
Common Signs of a Failing PCM
If you’re experiencing any of the following, a faulty engine computer could be the cause. Don’t keep throwing parts at the problem; address the source.
- ✔ Check Engine Light is on with codes like P0601, P0604, or P0605 (Internal Module Failure).
- ✔ The engine cranks but refuses to start.
- ✔ Unexplained drops in fuel economy.
- ✔ The transmission shifts harshly or at the wrong times.
- ✔ Intermittent stalling or a rough, unstable idle.
- ✔ Communication errors with your scan tool.
A Straightforward Guide to Installation
This installation is manageable for a confident DIYer with basic hand tools. For the 1998-2000 Bravada, the PCM is typically located in the engine bay on the right-hand (passenger) side.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the PCM: Find the module in the engine compartment. It’s a metal box with several large electrical connectors.
- Disconnect the Harnesses: Carefully unlatch and remove all electrical connectors from the old PCM. Inspect them for any corrosion or damage.
- Remove the Old Module: Unbolt the PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Bolt your new, pre-programmed PCM into place.
- Reconnect Everything: Firmly re-seat all electrical connectors until they click into place. Reconnect the negative battery terminal.
- Perform Security Relearn: Many GM vehicles of this era require a simple security relearn procedure to allow the engine to start. Typically, this involves turning the key to the ‘ON’ position for 10-15 minutes, then ‘OFF’ for 10 seconds, and repeating this cycle three times. Consult your vehicle’s service information for the exact procedure.

Frequently Asked Questions
Do I need to program this module?
No! This is the biggest benefit. We program the module to your vehicle’s specific VIN before we ship it. It arrives ready for installation.
What is a VIN and why do you need it?
The VIN is your 17-digit Vehicle Identification Number, found on your dashboard or driver’s side door jamb. It contains specific information about your vehicle’s engine, transmission, and options, which we use to load the correct software onto the PCM.
Is this part difficult to install?
For most DIYers with basic tools, this is a straightforward job that takes less than an hour. The most important part is performing the security relearn procedure after installation, which does not require special tools.
Will this fix my check engine light?
If the check engine light is caused by an internal PCM failure (like code P0601), then yes, this will resolve the issue. However, you should always diagnose other potential causes first, such as faulty sensors or wiring.
What part numbers does this replace?
This module is a direct replacement for service numbers 16263494, 16265035, 8162634940, and Hollander part number 218-11787.
