Do you own a 2001, 2002, 2003, 2004 or 2005 Toyota Rav4?
Are you having problems with the automatic transmission? The transmission acts erratically? Loss of power when accelerating or launching in other than first gear? Engaging very harsh in reverse? Slipping from 2nd to 3rd gear?
All those are problems caused by a defective ECM or Engine Control Module, a.k.a “Car Computer”.
The good news is that we have a solution for getting rid of the problem for good.
We are offering a REPAIR AND RETURN service for your Toyota Rav4 ECM (ECU). You send us your defective ECM, we repair and reprogram it and then it is shipped back to you. Our turn around time is one business day for most of the times or 2 business days when the workload is high. International orders are welcome too.
Shipping
ShippingWe offer FREE return shipping through USPS Priority Mail to continental USA, Puerto Rico, Hawaii, Alaska, Guam, American Samoa and US Virgin Islands. For international locations, return shipping cost will be calculated for FedEx shipping service. Return shipment to Canada can be served by USPS too, but unfortunately, we have no free options for it. We recommend FedEx for Canada though.
This is affecting more than a million units all around the world. It is so common that Toyota issued an “enhanced warranty” on this, which is long expired now.
This service covers 4WD Rav4 and 2WD Rav4 automatic vehicles. It also covers the Toyota Picnic and Toyota Avensis models of the same years (2001-2005).

Tampered Units
Did you already service your ECM with any other shop or Company and they could not fix it? or, did you try fixing it yourself following any video and realized that it does not work? No worries, we accept those units too. ECMs that have been serviced previously by other shops or units attempted to be repaired by yourself, may take a little more time because in some cases, we need to fix additional problems induced by any previous repair attempt, but we will gladly accept your unit and do our best to help.
Wouldn’t it be better if the ECM is replaced by a new one?
New or used (recycled) ECMs are giving the same problems, some in the long run and others in a few months. Also, the repair cost of the ECM is much less than the cost of a brand new replacement ECM. We offer the most complete service on these units, as we cover the whole unit, not just the transmission problem and not just the symptom of the problem, but the cause of the problem too.
Symptoms
The following are the most common symptoms of this issue with the ECM:
- Check engine is not triggered in most cases
- When Check engine is triggered, it commonly shows P0750, P0753, P0755, P0758 and/or P1760 trouble codes when scanned
- Hesitation or harsh shifting, mostly from 2nd to 3rd gears
- Slams into gear when putting it in reverse
- Sometimes it feels like braking by itself
- Erratically shifts on an intermittent interval
- Rattling or clicking noise coming from the engine bay when the engine is running, even if in neutral gear
- Some days fails and some days works with no issues
- The problem is there only when the engine gets warm or only when it is started the first time in the morning
- When stopping completely and moving again, it loses power and feels sluggish or heavy
- Lower fuel economy. Spends more gas than usual
ECM Part Numbers

ECM Location
Removing the ECM from your vehicle:
Tools you will need:
- Short #2 Phillips screwdriver (stubby)
- Regular #2 Phillips screwdriver
- 10MM Socket Wrench
- Flashlight.
The kick panel and the scuff plate should be removed first, before starting the ECM removal procedure (check the first drawing below).
Now, proceed to:
1. Open the glove compartment box. There are two plastic pins, limiting its opening, one on each side at the inner end of the box. Push the two inner edges inwards, so the glove box gets disengaged from its place.
2. Now, with the regular Phillips screwdriver, remove the two screws in the lower part, that are holding the glove box to the dash.
3. With the glove box completely out, find the ECM computer at the right, which is a metallic box with 5 wiring connectors on it. It is near a smaller metallic box.
4. Unplug the 5 white wiring connectors one by one, by pushing on a locking plastic clip that each connector have while pulling the harness out at the same time.
5. With the 10mm socket wrench, remove the 10mm head bolt that attaches the ECM to the bracket at the lower part (refer to the second drawing below) and with the short Phillips screwdriver, remove the two screws at the top.
You might need a flashlight here to easily find those two upper screws and you might also need to move away any wiring away that might be in the path for taking the ECM out.
6. When the ECM is loose, carefully slide it downwards. It will come out with the rear bracket attached to it, so when it is out, remove the four Phillips screws as shown in the second picture below.
That’s it. You may pack it in a small box and send it to us!

I have been driving my 2003 Rav4 for a couple days now and could not be happier with your services. I was only on my second tank of gas since purchasing it when i discovered it had shifting issues. My cars symptoms were very occasional. Sometimes a slightly harsh shift from 2nd to third. A few times it started out from a stop in a higher gear. Twice i noticed extreme slippage when shifting into 3rd. So I parked it and found you on the web.
The car now shifts perfect in every situation. I had an occasional low, slightly rough idle which i did not realize initially was related to the ecm and that is fixed too. It seems I caught it early enough before it damaged the transmission so all looks good.
I also have to mention i was impressed with your professionalism as far as communication and how quickly you turned it around and got it back to me.
Everything as advertised!
Thank You,
James B.

My car was behaving so weird, nothing was going well, car could not climb any hill and gallops on good road. The mechanic finally diagnosed it was the ECM that was faulty and no one could repair it out here in Cameroon. I researched online and met this company and i sent ECM to the US for them to repair it. My ECM was repaired, reprogrammed and tested before being shipped back to me. It worked perfectly well and my car is very ok now. Thank you very much Richard for saving my car.
