2001-2005 Toyota Rav4 ECM Repair Service

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 harsh in reverse like in a bump? 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 and prevent imminent damage to your vehicle’s transmission.

 

We are offering a REPAIR AND RETURN service for your Toyota Rav4 ECM (a.k.a 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

 

We 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 (out of the USA), return shipping cost will be calculated for FedEx shipping service. Return shipping to Canada can be done through USPS too, but unfortunately, we have no free options for it at this moment.

 

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 2001-2005 automatic Rav4 models, either 4WD (4 wheel drive or 4×4) and 2WD (2 wheel drive or 4×2). 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 and it did not work? No worries, no shame. We accept those units too. ECMs that have been serviced or attempted to be serviced previously by others or 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 WITHOUT adding any extra cost to the repair job.

 

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

Some common questions:

 

Wouldn’t it be better if the ECM is replaced by a new one?

 

Either brand new or used (recycled) ECMs are giving the same problems, the brand new in the long run and the others in a few months. Also, the repair cost of the ECM is a lot less than the cost of a brand new replacement ECM that would fail again in a few years if it is not corrected. We offer the most complete service for 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.

 

Do you actually repair or reprogram the ECM?

 

We do both. We first repair the circuit and replace any needed parts. Second, we reset the transmission adaptation table memory, so it starts relearning from zero when it is installed back. If your vehicle is equipped with the immobilizer security system, we reset it too to make sure the engine will start when installed back after it has been serviced. Third, we recondition the whole circuit to prevent future problems with any other area. Fourth, we check if there is an update available from Toyota for your unit. If there is one, we do the update by installing the latest software version available for your ECM. If your ECM’s software is outdated, it won’t leave our shop without been updated. Finally, it is tested in an actual vehicle. This is done with USA and Canada Market models. Japanese and European market models will be bench tested for transmission functions and vehicle tested for engine functions.

 

Will I have a tracking number?

 

Sure! When you send your unit to us and we receive it, we will notify you and will do the same when it is completed and shipped back and will notify you the tracking number. If you do not receive an email from us, it probably is in your email’s spam folder. To some users, we will try to notify from an alternative email if our system tells us that the email was denied or if it bounced. But when the system says “email delivered“, sometimes it lands in the “spam” folder. It depends on the way the email server of your email works. Our emails bounce the most from Yahoo mail. That is why, though it is optional, it is a good practice to (1) create an account with us when ordering instead of ordering as a guest and (2) leave your phone number in the order.

Warranty

 

We always stand by our customers. For our warranty on this service, please check the “Warranty” tab on this page.

 

 

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 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!

Yes

Warranty

 

The included warranty term (stated at the top of this page) covers the job done in the ECM and any parts replaced. In the rare event that the ECM fails again, showing the same or similar problems as before, we will consult the customer about the symptoms and if the ECM is suspected to be the culprit, it will be taken back for service at no cost for the job or parts.

 

While the job would be done at no cost and needed parts would not be charged in the period covered by the warranty term, inbound and outbound shipping costs will depend on the case, as explained below.

 

Shipping coverage

 

A. If a claim is filed anytime within the warranty period and the problem is caused by something we did wrong (errors or mistakes in the repair process), if it happens in the first 30 days of the warranty period, we will cover both ways shipping. If it happens after the first 30 days of the warranty period, then we could only cover return shipping (from our location to the customer’s location).

 

B-1. If the claim is filed within the warranty period and it was not our fault, for example, a different part or different circuit is damaged this time and it was not caused by our previous intervention with the ECM, or (B-2) the same part is damaged, but because of an external cause**, then we will still cover the job and parts, but the customer would need to cover both ways shipping.

 

**Definition of “External Causes”

 

1. The ECM was soaked in water or any other liquid.

 

2. The ECM fell from a considerable height or was hit hard (ex. an accident), causing internal damages to the circuit.

 

3. Short circuit in the vehicle’s wiring or problems with the electrical system of the vehicle.

 

4. Battery polarity reversed.

 

5. The ECM was used in an application that it is not intended for (different car or different setup).

 

6. The ECM was tampered with, either by opening it or by connecting wires to the ECM’s terminals other than the ECM’s wiring harness.

 

7. The use of piggybacks – External modules connected to the ECM terminals in order to modify the received signals (mostly done for engine performance).

 

8. Broken warranty seals indication tampering.

    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.

    Repair of my 2001 Rav4 ECM

    Clarisse L

    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.

      Hello Larry. We have many reviews, but since we moved here from a previous website, we are still integrating other functions of more priority. Reviews will be imported from our old website later on. The ones here were left after we moved in. Thank you for your comment.

Question about 2001-2005 Toyota Rav4 ECM Repair Service


Name (required):


Email (required):


Your Question or Inquiry (required):





Here are some questions that are frequently asked about this service.
1. What do I need to send to you for this service?
ANSWER: We only need the ECM to be repaired, please without the brackets. The ECM has three brackets for attaching it to the vehicle. If you include the brackets, it will be more difficult to ship and shipping will also cost more, as the extra space that the brackets take will demand a bigger package.

We understand that sometimes, either the screws used to attach the brackets are very, very tight and the screw head gets deformed in the attempt of removing it, or in some other cases, the manufacturer uses non-standard security Torx screws instead of the common Philips screws. In those cases, just send it with the brackets.
2. May I send only the circuit board? You know, without its metal case?
ANSWER: Unfortunately, even when shipping would be even lighter that way, we can not accept units without its metal case. A warranty could not be offered if the unit comes without its metal case, as the unit would be vulnerable to shipping damage and tampering.
3. My vehicle has the immobilizer feature. Do I need to send you the car keys along with the ECM?
ANSWER: No, we do not need the keys. We will reprogram your ECM in a way that it will re-register and work with your current keys.
4. Do you need the VIN number?
ANSWER: No. It is not needed and not altered either during this service. Different from other Toyota models, the VIN number is not stored in this ECM.
5. Do you reprogram the ECM as part of the service?
ANSWER: Yes, in two ways; (1) we reprogram the transmission adaptation table memory. That is, the wrong codes learned by the ECM because its own failure are cleared so it relearns the correct codes when it is reinstalled and (2) if the ECM requires an update of its internal software (firmware), it is done with the latest version update from Toyota. We always check that every ECM we service has the latest software version before it is shipped back to our customers.
6. You charge a shipping fee. Do you send a shipping label for shipping the ECM to you?
ANSWER: No, we don't. Shipping to our location is done on the customers' behalf. The shipping fees we charge are for sending the repaired ECM back to you. This charge is FREE if shipped to the USA. In those cases, it is shipped through USPS Priority Mail (3-5 business days). Paid shipments are also available if a faster shipment is needed (USPS Express Mail and FedEx). Unfortunately, we have no free shipping options for international shipments at this time.
7. Do you accept international orders?
ANSWER: Yes. International orders are welcome. We offer our service to all countries. Shipping to international locations (out of the USA) are done through FedEx. Canada is served either by USPS or FedEx.
8. I have an account with a shipping company (USPS, FedEx, DHL, UPS, TNT, ARAMEX etc). Can I pay only for the service and ship using my account with such a company?
ANSWER: Sure, it can easily be done. just let us know and we will do the arrangements. We do not profit from shipping, nor we charge any handling fees. The rates we use are directly returned from USPS and FedEx APIS (Application Programming Interface) that are directly connected to our website when doing the calculation. So if you want to use your own shipping account it can be fixed no problem.
