Restore Peak Performance to Your GM Truck or SUV
As a technician with over two decades of experience under the hood, I’ve seen firsthand how a failing Engine Control Module (ECM) can turn a reliable vehicle into a source of constant frustration. If your 2017 Yukon is experiencing bizarre electrical gremlins, poor fuel economy, a persistent check engine light, or even a no-start condition, the ECM is often the culprit. This isn’t just a part; it’s the central computer of your vehicle, and when it falters, everything else does too. We’re offering a dependable and straightforward solution: a replacement 2017 Yukon Engine Control Module, professionally programmed to your vehicle’s specific VIN.
Forget the hassle and high cost of a dealership visit. We take the guesswork out of the equation by flashing this module with the latest official GM software updates before it even leaves our facility. All we need is your VIN during checkout. This ensures that when you receive the part, it’s ready to communicate with your vehicle’s specific systems, restoring the precise engine management, fuel delivery, and emissions control it had from the factory.
From the Diagnostic Bay: The Ghost in the Machine
I remember a 2017 Sierra 1500 that came into the shop with an intermittent no-start condition that was driving the owner crazy. The battery was new, the starter checked out, and the fuel pump was priming. It would start fine for a week, then refuse to crank for two days. After hours of tracing wires and checking grounds, we hooked up our high-level scan tool and noticed intermittent communication loss with the ECM (a classic U0100 code). On a hunch, we swapped in a known-good, programmed ECM. The truck fired up instantly and never had the problem again. The original module had an internal hairline fracture on the circuit board, a common failure point from years of heat cycles and vibration. This is the kind of tricky issue that a quality replacement ECM solves definitively.
Common Signs of a Failing ECM
- ✔ Check Engine Light is on with codes like P0601, P0606, or U0100.
- ✔ Vehicle refuses to start or has intermittent starting problems.
- ✔ Noticeable drop in fuel efficiency.
- ✔ Engine stalling, sputtering, or misfiring for no apparent reason.
- ✔ Poor or erratic automatic transmission shifting.
- ✔ Communication issues with diagnostic scan tools.
A Straightforward Guide to Installation
Installing your new 2017 Yukon Engine Control Module is a manageable job for a confident DIYer or any professional mechanic. The key is our pre-programming service, which handles the most complex step for you.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the ECM: On most compatible GM trucks and SUVs, the ECM is located in the engine compartment, typically on the driver’s side (LH).
- Disconnect Connectors: Carefully release the locking tabs and unplug the wiring harnesses from the old module. Inspect the connectors for any corrosion or damage.
- Remove the Old Module: Unbolt the old ECM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed ECM and securely reconnect the wiring harnesses. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Theft Deterrent Relearn: In many cases, the vehicle will start right up. However, if it doesn’t, a Vehicle Theft Deterrent System (VTDS) relearn is required. This is a standard security procedure that syncs the new ECM to your vehicle. This process requires a GM-compatible scan tool with access to TIS2Web or Techline Connect. This step, along with any other necessary relearns (crankshaft position, injector flow rates), is the responsibility of the installer.

Do I have to send you my old ECM?
Do I have to send you my old ECM?
No core charge or return is required for this part. You can keep your old module.
What happens if I don’t provide my VIN?
We cannot ship the module until we receive your vehicle’s 17-digit VIN. The programming is essential for the part to function correctly in your specific vehicle. Please provide it in the notes at checkout or send us a message after your purchase.
Is the theft relearn procedure difficult?
For a professional technician with the proper GM diagnostic tools (like Techline Connect), it’s a routine procedure that takes only a few minutes. For a DIYer without these tools, you may need to have a local mechanic or mobile technician perform this final step for you.
Will this fix my specific problem?
