FAQs

Q1. Will this ECM fit my 2011, 2012, or 2013 Nissan Altima 2.5L?

A. Yes. This is a genuine OEM engine control module (ECM/ECU/PCM), part number MEC112-130, for the 2011-2013 Nissan Altima with the 2.5L engine. It also covers interchange numbers 1X14A, 590-61713, and MEC112-130 B1. Confirm the number on your current module matches, or send us your VIN and we will verify the fit.

Q2. Is the Altima ECM plug-and-play, or do I have to program it?

A. It ships plug-and-play. We program the ECM to your VIN before it leaves us, so you unplug the old unit and plug in the new one in the same spot. Some Nissans then need the keys re-registered to the new ECM (NATS anti-theft relearn) and a quick idle-air-volume relearn — see the immobilizer question below.

Q3. Why do you need my VIN to program the Altima ECM?

A. Your 17-digit VIN lets us load the correct factory calibration for your exact Altima before shipping. You provide it at checkout; if it is missing we reach out before shipping. Find your VIN on the driver's door-jamb sticker, the base of the windshield on the driver's side, or your registration.

Q4. Will I need to re-register my keys or immobilizer (NATS) after installing the ECM?

A. Possibly. On many Nissan Altimas the keys must be registered to the new ECM through the NATS anti-theft system after installation, and the vehicle may need an idle-air-volume relearn. A Nissan dealer, an automotive locksmith, or many capable scan tools can complete this in minutes. Contact our support team and we will tell you what your vehicle needs.

Q5. Is this a genuine OEM Nissan part or an aftermarket copy?

A. It is a genuine OEM MEC112-130 module that we remanufacture and test in-house — not an aftermarket clone. We restore the original factory unit and bench-test it with ASE-certified technicians before shipping.

Q6. What are the symptoms of a bad Altima ECM?

A. Common symptoms include a no-start or hard-start condition, stalling, a check engine light with multiple or communication-related codes, poor performance or fuel economy, and no communication with a scan tool. Confirm the ECM is the cause before ordering; our team can help you read your codes.

Q7. Will this ECM fix my check engine light?

A. If your diagnosis points to a failed ECM, installing this correctly programmed replacement should clear the module-related codes and turn off the check engine light. If the underlying cause is a sensor, wiring, or mechanical fault, that problem must be repaired as well.

Q8. How long does it take to install the Altima ECM?

A. The physical swap usually takes about 15 to 40 minutes because the ECM ships pre-programmed. Allow a little extra time if your vehicle needs the NATS key registration or idle relearn afterward.

Q9. Do I need to send in my original ECM (core)?

A. Some ECM orders require your original unit as a core or for data transfer; others do not. This product page notes if your original module is required, and when a core is needed you typically send in the old unit after receiving the replacement.

Q10. What warranty comes with the Altima ECM?

A. It includes a 6-month warranty plus lifetime phone support. The warranty is full for the first 3 weeks and prorated after that. If a covered module fails, contact us and we will make it right under the warranty terms.

Q11. Is the ECM tested before shipping?

A. Yes. Every unit is bench-tested by ASE-certified technicians before it ships. We repair and test modules in-house, so the ECM you receive has been verified to function before it leaves us.

Q12. How much does the Altima ECM cost and what is included?

A. The ECM is priced at $324.00 and ships programmed to your VIN, tested, and ready to install plug-and-play (some vehicles need a NATS key relearn afterward). [REVIEW: confirm current price and note if anything else is included, such as free shipping.]

Q13. How fast will the ECM ship?

A. Orders are programmed and shipped quickly, and most units ship within Business days once we have your VIN. You receive tracking as soon as it ships.

Q14. What is your return policy on this ECM?

A. Contact us before returning any module so we can issue return instructions and an authorization.

Q15. What if I get stuck during installation or the relearn?

A. Lifetime phone support is included with every module. Our ASE-certified team can walk you through installation, the NATS key registration, the idle relearn, and any troubleshooting for as long as you own the part.
