This OEM Engine Control Module (ECM) was removed from a 2007 Lexus ES350 equipped with a 3.5L V6 engine and automatic transmission. The ECM was originally mounted by the glove box compartment and has been professionally inspected by our technicians. This genuine Lexus part is currently on our shelf and ready for immediate shipment to get your vehicle back on the road.
The Engine Control Module is the brain of your vehicle’s engine management system, controlling fuel injection, ignition timing, emissions systems, and transmission operation. ECMs commonly fail due to electrical surges, water damage, or internal component degradation over time. When your ECM fails, you may experience no-start conditions, rough idle, poor fuel economy, transmission shifting issues, or various warning lights on your dashboard.

Yes, this ECM will need to be programmed by a qualified technician or dealership to match your vehicle’s VIN and security system. Programming is required for proper operation and cannot be done without professional diagnostic equipment.
Common symptoms include engine not starting, rough idle, stalling, poor fuel economy, transmission shifting problems, and check engine or other warning lights. A professional diagnostic scan can confirm ECM failure versus other potential issues.
This ECM is specific to the 2007 ES350 with 3.5L engine. While some Lexus models may share similar ECMs, programming and connector differences require the exact part for your specific year and engine combination.
ECMs can fail due to electrical surges from jump starting or alternator problems, water damage from floods or leaks, overheating, or simply age-related component degradation. Power supply issues and corroded connections are also common causes.
While the physical installation involves removing the old ECM and connecting the new one, professional programming is required afterward. The ECM must be programmed to your vehicle’s VIN and may require security system initialization by a qualified technician.

RatingI'm replacing damaged panels on my 2006 Ridgeline on a tight budget so I may quickly sell it and they were so helpful and priced better than anyone else in the area. Raised a glass of scotch for these ladies! Thanks again!
Great service! The best price and condition for the Porsche Cayenne parts needed to finish the job. Radiator core support and headlight fit perfectly!
Drove from new york, Julie was a sweetheart asked questions to make sure that my ECU was the proper part number and was compatible with my manual Accord, price was phenomenal I highly recommend them for any parts your car may need. Definitely the best salvage yard around
Great experience at 603 Auto Salvage! ⭐️ The owner and employee were both extremely helpful and easy to work with. I was able to find everything I needed in one stop — about seven different items — which saved me a lot of time and hassle. Good selection, fair pricing, and friendly service. Definitely recommend checking them out if you're looking for parts. I’ll be back again! 👍🔧🚗
I had a great experience with 603 Auto Salvage Inc. The team was very helpful and quickly found the exact part I needed. They kept me informed and made the pickup process easy. The price was very fair, and the service was excellent. I would definitely recommend them and will use them again if I need parts in the future.

The customer service at 603 was great. They found the part I needed very quickly and promptly notified me when it was ready to be picked up. There wasn’t any other place in the area that had what I needed. The price was very good also. I will be using them again for sure.
I had a great experience. They didn’t just look up the part I needed they took the time to explain how to install it and made sure I understood everything. I even received a call back, which I really appreciated. Everyone I spoke with was friendly and patient, and I never felt brushed off. I truly felt taken care of. Highly recommend if you want knowledgeable people who actually care about helping you. Kristy Thanks Guys!
Drove from Connecticut to get here. Had parts for a relatively rare car that dozens of other places didn't have. I got a hood, fender and bumper cover that were in near mint condition for a fifteen year old car. They pulled all the parts for me and had everything ready within an hour. Very reasonably priced. Highly recommend
Exceptional service, large selection of parts, will come back if more Audi parts are needed. A++
