06-07 Chevy GMC 6.6L Duramax LBZ ECM Engine Computer REPAIR SERVICE 12606126 For Sale

DriveTech Electronics6.6L Duramax LBZ ECMRepair Service

We rebuild your own engine computer at component level and send it back running - with every bit of your factory programming still on it. You are not receiving a replacement ECM. You send us your own unit, we repair it, and the same unit comes back to you. Most units are repaired and shipped back within 1 business day of arriving, occasionally 2, counted from the day your unit reaches our bench. Lifetime limited warranty on the repair we perform. Zero programming needed on reinstall because your VIN, calibration, theft-deterrent (Passlock) password and injector flow rate (IQA) codes stay on the board. Standard return shipping back to you is included, and a faster return is an optional $60 upgrade. Fits the 2006-2007 6.6L Duramax E35 ECM: 2006 Silverado and Sierra 2500HD and 3500 (8th VIN digit D, or 2 for the 2006 LLY-tune engine, which uses this same ECM) and 2007 Classic-body Silverado and Sierra 2500HD and 3500 (digit D). 2006-2007 Express and Savana 2500/3500 diesel vans and C4500/C5500 Kodiak and Topkick trucks with a matching ECM number are also covered. Several part numbers were used across this platform and we run a separate listing for each - match the number printed on your unit to the number in the item specifics above before ordering.

If you wanted to buy a working computer outright, this is not that listing.SymptomsWhat we fixCrank, no startEngine turns over but never firesNo communicationScan tool cannot reach the ECM at allInjector driver failureThe injector drivers are built into this ECM, so a failed driver is an ECM repairP0201-P0208Internal processor faultsThe module reporting its own failureP0606On a tuned truck, P0606 can come from the tune itself; return to a stock or known-good tune before sending your unit.Stalling and random shutdownDies while driving, restarts like nothing happenedCompletely dead unitNo power up, no response, no signs of lifeCommon finds are cracked or cold solder joints and failed injector-driver components. We repair at component level and bench test under load, not just for power-up.The advantageYour programming never leaves the board

This is your original ECM going back into your truck. Your VIN, calibration, theft-deterrent password and injector flow rate (IQA) codes all stay exactly as they were. Which means:

Not neededNo programmingNot neededNo VIN codingNot neededNo relearnNot neededNo dealer visitIt bolts back in and the truck runs. That is the whole reason to repair yours instead of buying a replacement that has to be flashed.The processHow it works01PurchaseWe send you the return address right away.02Ship it to usBuyer pays shipping to us.

Standard turnaround covers most people. If you need it sooner, pick one of these - not both.

Option AExpress Return$60Upgrades the shipping only. Your unit moves through the bench in normal order - it just gets home faster once it is done.Option B - FastestRush Repair + Overnight$100Your unit goes to the front of the bench queue and ships back overnight.

Want either one? Message us before you ship your unit and we will set it up.

WarrantyLifetime limited warranty on the repair we performIf the repair we did fails, we stand behind it. It covers our work - not a new unrelated failure, physical or water damage, a wiring or injector fault elsewhere in the truck, or improper installation.PricingIf your unit needs more than a standard repair

Most units are a standard repair - you pay the listing price and nothing else. If one comes in worse than expected, we stop, contact you, and quote you first. Nothing extra is ever charged without your approval.

This service covers the 6.6L Duramax ECM listed in the item specifics above. Typical applications, 2006-2007:

Chevrolet Silverado 2500HD / 3500 (2006; 2007 Classic)GMC Sierra 2500HD / 3500 (2006; 2007 Classic)Chevrolet C4500 Kodiak / C5500 Kodiak 6.6L Diesel (2006-2007)GMC C4500 Topkick / C5500 Topkick 6.6L Diesel (2006-2007)Chevrolet Express 2500 / 3500 Diesel (2006-2007, matching ECM number)GMC Savana 2500 / 3500 Diesel (2006-2007, matching ECM number)

2007 was a split year. Classic-body pickups have the LBZ (8th VIN digit D); 2007.5 New Body pickups have the LMM (digit 6) and need our LMM ECM repair listing. 2007 vans were also split, so match the number printed on your unit. The 2006 LLY-tune engine (8th VIN digit 2) uses this same ECM. On C4500 and C5500 Kodiak and Topkick trucks, match the number printed on your unit as well. Not for 2001-2004 LB7 or 2004.5-2005 LLY trucks, which use a different computer.

Several part numbers were used across this platform, and we run a separate listing for each one. Match the number printed on your unit to the number in this listing before ordering - or send us your VIN or a photo of the label and we will point you to the right listing before you buy.ImportantBefore you pull the ECM - read thisInjector circuit codes are often caused by an injector or the injector harness, not the ECM. Have the injectors and harness tested before you reinstall, so the same fault is not waiting for your repaired unit. Message us - we will walk through what your codes point to.ShippingGetting it here and backTo usShipping to us is paid by the buyer. Pack the module in a rigid box with real padding on every side, and use a tracked service. If we haven't heard from you that your unit has shipped within 3 business days of your order (weekends excluded), we'll text and email you a free prepaid shipping label.Back to youStandard return shipping is included. A faster return is the optional $60 Express Return upgrade above. Orders totalling $400 or more ship back with signature required on delivery.Not sure it is your ECM?Message us through with your VIN, your codes, or a photo of the label. We would rather answer a fitment question up front than have you order the wrong service.DriveTech ElectronicsRepair. Return. Warranty for life.
