Yes, most Honda ECMs require programming to match your vehicle’s VIN and security system. This should be done by a Honda dealer or qualified automotive locksmith with Honda programming equipment.
Common symptoms include check engine lights, poor fuel economy, rough idling, stalling, or failure to start. The ECM may also cause transmission shifting problems or trigger multiple error codes.
ECM (Engine Control Module) specifically controls engine functions, while PCM (Powertrain Control Module) controls both engine and transmission. ECU is a general term for Electronic Control Unit covering various vehicle systems.
While physically replacing the ECM is straightforward, programming requires specialized equipment. Most DIY installers can handle the removal and installation but will need professional programming services.
Honda ECMs generally last 150,000-200,000 miles or more. Failures are often caused by electrical issues, water damage, or voltage spikes rather than normal wear.
Common causes include electrical surges from jump-starting, water damage from flooding, corroded connections, or internal component failure. Heat and vibration can also contribute to ECM degradation over time.

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++
