2001 2002 2003 Toyota RAV4 ECM / ECU Repair Service
Do you own a 2001, 2002 or 2003 automatic Toyota RAV4? Having transmission shifting problems? Erratic problems? Power loss? Is transmission slipping? Read on. In 98% cases it is a faulty ECM (ECU). It is been informed that around 235,500 RAV4 models might be affected with this issue on the ECM. That is; 77,100 units from 2001 models, 87,600 units from 2002 models and 70,800 units from 2003 models.


We are offering the service of repairing your 2001, 2002 and 2003 Toyota RAV4 ECM which is also known as car computer, ECU, engine control module or engine control unit. This service is for either 4x4 (AWD - All Wheel Drive) or 4x2 (FWD - Front Wheel Drive) vehicles, equipped with automatic transmission.


***Customers from Asia, Europe, Africa and Australia, you are all welcome, but please, check an IMPORTANT notice below in a red frame about sending us your ECM for repair.***



The ECM of these RAV4 models are failing and as a result of this failure, the transmission starts slipping (mostly from second to third gear) and showing other shifting problems, like starting from zero in third gear instead of first gear, making it sluggish when it is accelerated. RPMs go up and vehicle barely starts to move. This, among many other symptoms, which are listed further below.


If this situation is not solved on time, the transmission will suffer an internal failure, making the problem worse and a lot more expensive to fix. Like if it were not enough, owners even have reported having minor accidents because of the malfunction of the vehicle while having this issue. Citing the words of one of our customers before we serviced his ECM, "lately, this is been kind of a dangerous car...".


The good news is that the Toyota RAV4 really is a very dependable car and the issue on these models has a cure! Bring us your ECM and you will see the difference!


This issue will only be solved by either (1) replacing the ECM computer by a new one, or (2) by sending the ECM to us for repairing it. A reprogramming alone will NOT solve the problem, as suggested by many dealers.


If you decide to replace your ECM, a new ECM will cost from $1000 - $1300. If you get an used ECM, it will be prone to fail for the same issue, unless PROPERLY repaired and if it has the immobilizer security system enabled, it must be programmed first, before you can use it in your car.


The best choice is our professional service. We repair and reprogram your actual RAV4 ECM computer. When we ship it back to you, it will be ready to be installed and used right away (plug and play). No programming will be needed. No trips to the dealer. We eliminate all the following problems that this ECM might be causing to your RAV4:


  • Erratic Shifting
  • Transmission slips any gear, but mostly from second to third gear.
  • Starting in 3rd gear and shifting erratically or not shifting
  • Rattling noise coming from the front area when parked with engine running
  • The feeling of applying the brakes by it self in some occasions
  • False solenoid codes P0750, P0753, P0755, P0758 and/or P1760
  • The codes above not always show (DTC codes). Sometimes it fails with no codes at all or no check engine light
  • Engages hard in reverse with a "bump" or takes time to engage
  • Symptoms are intermittent. Sometimes symptoms show only when warm or when cold and sometimes symptoms don't show at all
  • One day it runs OK and all the symptoms magically disappear and the next day all or some of those symptoms are back
Toyota extended their warranty specifically for this issue, only for vehicles sold and currently in USA, and only for original owners with proof of ownership. The extension was made to 10 years or 150,000 miles, whichever comes first.


If your RAV4 is over 150,000 or if you wish to take care of this right now, we will gladly help and repair it for you.


We do a high quality job and take preventive measures to avoid this from happening ever again. A warranty, stated in the information box above at the top is included with all repair jobs.


If your ECM is equipped with the factory immobilizer system, it will NOT be a problem at all. You will NOT need to program, reprogram or bring your RAV4 to a dealer in order to use it after this service is done. Just re-install the ecu after receiving it back from us and it is ready to drive your new-again RAV4.

Take action now! Don't allow the transmission to fail by driving your RAV4 while having these problems. A transmission repair job may cost you up to $5000.


IMPORTANT: Worldwide orders are accepted, but if you are sending us your ECM for repair from Europe, Asia, Africa or Australia, we highly recommend to use FedEx, UPS or DHL. We DO NOT recommend using any other services on this specific case. Otherwise, Customs brokerage fees of $200 may apply and must be collected (charged to the customer) before the ECM is returned. FedEx, UPS or DHL will not generate this charge.



If you are interested in a new ecu unit, we can help too! We offer a BRAND NEW, NEVER USED RAV4 ecu / ecm at the link below:





A few examples of RAV4 ECM units that are having these problems are listed below, but there are several more, so don't hesitate on asking us or acquiring the service if you don't see your ECM's number on this list. If it is an Automatic, 2001, 2002 or 2003 Toyota RAV4, either 4x2 or 4x4, then it is one of the affected models.

Toyota RAV4 ECM repair FAQ


What do you do? Do you reprogram or repair the ECM?

We repair the circuit of the ECM and then reprogram it. A reprogramming alone will not fix the transmission problem. The reprogramming is done to the transmission adaptation tables, which are located in a memory chip in the ECM's circuit. The repair process includes replacing any damaged electronic part and reconditioning of the circuit, to avoid this from happening ever again.


May I have a copy of the bulleting distributed by Toyota about this?

Sure! Below you may download the official Toyota bulleting issued for this:

T-SB-0156-10

and below, is the warranty extension bulletin issued to the service managers and warranty administrators:

2001-2003 Toyota RAV4 Warranty Enhancement



Where are you located?

We are located in USA. For shipping your ECM to our location if you are in the United States (USA), including its territories or protectorates, it can be easily done through US Postal Service (USPS), either through Priority or Express Mail services, just as shipping to any of the US States.

If you are sending your ECM from outside of the United States, specifically from the non-USA Caribbean, Canada, Central America or South America, then it can be done through your current postal system or through FedEx, UPS or DHL.

Finally, if you are located in Asia, Europe, Australia or Africa, then those three services mentioned before (FedEx, UPS or DHL) are the only ones accepted. Other services may be used, but if you send your ECM from any of those Countries and use any shipping service other than FedEx, UPS or DHL, a Customs brokerage fee of $200 will apply.


Is it hard to remove the ECM from the vehicle? Is it a mechanic needed for the job?

Not really. It is a matter of removing several bolts. For doing so, a short Phillips screwdriver and 10mm socket head wrench will be needed. Other than that, you will need to disconnecting the 5 plastic connectors attached to the ECM, by simply pushing a clip on each connector and pulling it out.

However, because of the small area where it is installed, it might be somewhat difficult to handle and remove from its place. If you are doing it yourself, take extreme caution not to cut yourself with any sharp edges around the area.


My ECM is not on the list shown. May I send it to you?

If it is from a 2001, 2002 or 2003 Toyota RAV4 with automatic transmission, either 4x2 or 4x4, yes, we will fix it. There are more ECM types affected than the ones listed on our page and more than counted on Toyota's bulletins, as those bulletins cover only ECMs sold in the USA, but more units are affected with the same issue.

We have serviced units with the same problem, coming from Australia, several locations of East and South Africa, South America, Central America, many locations from Europe and some from Asia. All units serviced are for the 1AZ-FE engine, but some units serviced are for the 1AZ-FSE stratified direct injection engines. What these units have in common, and this is mentioned only as a way of identifying them, is that all the ECMs with this issue are made by the Fujitsu Ten company, not Denso or Delco, as some other Toyota ECMs.

Note: As mentioned above, this is only for identification purposes. Fujitsu Ten is an excellent electronics Company, the same as Toyota is an excellent automotive Company. RAV4 vehicles are very dependable and once this issue with the ECM is corrected, applicable only to 2001-2003 automatic models, it will last a lifetime.


Will my RAV4 pass the smog test (emissions test) when doing inspection of my RAV4 if I get this service?

Short answer, YES. Long answer, if it passed the emission tests before the problem showed up, it will then pass the test after the service. This service will not alter in any way the engine's combustion parameters, mixtures, performance or factory specifications at all. We have received reports of the vehicle performing better than before, but it is because of the transmission shifting properly now. If the ECM issue caused somehow to not pass the test, then after repaired it will pass without a problem.


What are the engine specifications of these RAV4 you are servicing their ECMs

Engine is 4 cylinder, 2.0L, either the 1AZ-FE or 1AZ-FSE Toyota engines.


Do I need to program or do anything else that require a trip to the dealer in order to use my repaired ECM?

No, not at all. Your ECM will be "plug and play" after you receive it back. That means that you just reinstall it in your RAV4 and it will be ready to use. No programming, no trips to the dealer and no towing your RAV4 to the mechanic will be needed at all. You will start enjoying your new-again RAV4 as soon as the ECM is serviced and reinstalled.


People tell me that these ECMs will lock once serviced and will need to go to the dealer so they can fix that. Is it true?

Short answer, NOT with us. Detailed answer, Yes, it might happen if the ECM has the immobilizer system enabled and the technician does not do the job properly or does not know how to handle it(other shop).

We always prepare our customers' ECMs so they are ready to start the engine as usual when installed and can be used right away. If your ECM has the immobilizer system enabled, it is not a problem for us. We will know just by reading the memory of the ECM and will program it accordingly so it works with your keys and only with your keys.


You charge an amount for the job, plus shipping. How does shipping work?

The shipping fee we charge is for covering the return shipment. That fee will pay the shipping service used when we return the repaired ECM to you.


I have more than one ECM. Do you offer combined shipping or any other discount?

Yes, we will ship up to 2 ECMs in the same box for the shipping charge of one, if shipped Internationally (outside of the USA). If shipped in the USA, we will ship up to 3 ECMs in the same box for the shipping charge of one. About the job charge, if you send 2 ECMs to be repaired, we will take off 20% ($50.00 out of $250.00) to the second ECM, if it is not in special price offer and the 2 ECMs are sent together.


What warranty do you offer and what does it cover?

We include a one year warranty. It covers the repair job itself. In the rarest occasion that your ECM fails with the same symptoms (not happened yet), we will take care of it and if it is the same problem we worked on, we will solve it at no cost. We will even cover shipping charges.

"The same problem" in the above statement means that the circuit has the same part or parts damaged again and it was not an external cause. "External cause" is defined as a short circuit in the vehicle's circuitry, ECM used in the wrong car model, ECM fell into the water or any other liquid, ECM fell down from a considerable distance to a hard surface, where "considerable" in the previous statement means "enough to harm the circuit", the ECM was smashed or metallic debris in the ECM connector when it was reinstalled caused the malfunction and some others not controlled by us or are not related to our service.


How much time will this service take?

We generally take only one business day. On days when workload is high, we might take up to 2 business days. The rest of the time it will take, will be shipping transit time, which will generally be 2 to 5 business days if mailed inside the United States, US Territories and US Protectorates and 6 to 10 business days if shipped to international destinations (outside USA).

If shipped to international destinations (outside USA), it must be added up the time it might take in customs on the Country of destination, which depending on the Country, might be from 1 business day to more than 12 business days. This is greatly improved if using services like FedEx for return shipments, which might take up to a total of 5 business days to many destinations. To get the ECM returned to you through FedEx, please let us know, so we can send you a personalized Invoice, while we integrate FedEx to the shipping system.


How does this service work? Do you send an ECM after I pay?

No. Right after you order the service, we will be awaiting for your ECM to arrive, so it can be repaired, reprogrammed and tested and then shipped back to you.

Unfortunately, we no longer can send an ECM beforehand while your ECM arrives, due to the ever increasing demand on this service. Each day these refurbished ECMs are becoming more scarce and new ones are becoming more expensive.


Is the ECM the same as ECU?

Yes, it refers to the same automotive part. ECM stands for Engine Control Module and ECU stands for Engine Control Unit, but refers to the same.


If the ECU is "Engine Control Unit", why should I send it for repairing a problem with the transmission?

In the case of the automatic 2001-2003 Toyota RAV4 model, the ECM controls both, the engine and the transmission. In other automatic car models and brands, there are two separated units, one for each part. The engine unit would be the ECM or ECU and the transmission unit would be the TCM or TCU.


Do you offer this service to XXX country?

Yes, we repair RAV4 ECMs from all around the world. All Countries are welcome.


How should I pack my ECM when shipping it to you?

Just send it in a small box, wrapped with some paper, plastic wrap any packing material of your choice (newspaper is fine). The construction of this ECM is pretty tough and withstand moderate impacts. So far, all incoming ECUs have arrived OK, even those that came packed in a plain bag.


My RAV4 has the immobilizer system. Can you still service my ECM?

Sure! You will have no problems with the immobilizer or with starting the engine with your keys (transponder keys). It will be ready to use as soon as you receive it.


I depend a lot of my RAV4. What could happen if I keep using it like that?

Using your RAV4 with this issue may cause the transmission to have an internal failure and then, the ECM and the transmission will both need service. There are occasions, where the failure in the ECM makes the transmission to start in third gear, instead of first gear. In that moment, you will feel your RAV4 like if it is very heavy, hard to start moving from zero and the RPMs go up and still it is slow moving. It is in that moment when the clutches and other parts inside the transmission start to burn and fail.

If you have ever ride a multi-speed bicycle, let's say 15 speeds, it would be like starting from zero in around 13th speed. The bicycle have no clutches, but you will feel the burning in your muscles in no time.


Is it really the ECM and not the transmission? It slips and jolts and feels like the transmission is really broken!

Yes. Remember that the ECM controls your RAV4's automatic transmission electronically, by doing the shifting through solenoids. These solenoids are electromechanical parts that are incorporated in the transmission body and do the physical shifting (mechanical movement) by receiving electrical pulses sent from the ECM. When the ECM is failing, it sends erratic pulses to those solenoids and make it so annoying that makes us feel that the problem is the transmission, but it is not.


Is there a chance that the transmission could be damaged besides the ECM?

Yes. The ECM must be repaired and that is a fact, but depending on how much you use your RAV4 after the failure shows up for the first time, it will be the difference between an ECM repair only and an ECM plus transmission repair job.

It is very important that once the ECM failure is present, you stop your RAV4 and either replace or repair the ECM.

Do not hesitate in sending your ECM to repair, as according to our experience, 98% of the cases were solved by just repairing the ECM.
