2001-2002 Toyota RAV4 Immobilizer Virgin Dump

Do it yourself - immobilizer reset. This is the virgin dump for the ECM of the 2001 - 2003 Toyota RAV4 Immobilizer.

What is this? - This is the software or code that goes inside the immobilizer chip, located in the ECM, that will reset the Immobilizer, so the vehicle accepts your current or new keys. It is also known as firmware or dump. It is composed of only 1 KByte (1024 Bytes) file in binary format.

Will this fix the transmission problems of these models? - No, this will make the ecm ready (plug and play) if it was repaired or remanufactured or if it is used, sourced from a recycler, junkyard or any other source like eBay and sold to a customer, so the customer will not need to reprogram it to use it.

For using this, you will need an EEPROM programmer and a special connecting clip for either programming it on circuit or off-circuit. The EEPROM programmer can be any inexpensive type, able to accept serial EEPROMs like the 93c56, 93c66, 24c02, 25020, 25080, etc. and the clip is sold by the 3M Company and Pomona, with a cost of about $15.

The clip is known as an SOIC-8 SMD clip and can be acquired at online electronic catalogs like Digikey.com. The target EEPROM on this case is the 25080 EEPROM.



You take out the ECM from your vehicle, open it, locate the small 8-legged chip and reprogram it with the included code and then you are ready to reinstall the ECM back in your vehicle and drive it with your existing old or new keys. No soldering/desoldering needed, that is the purpose of using the SOIC-8 clip. This code can be used as many times as you wish, as the EEPROM is completely re-programmable and also you can do this on as many vehicles as you wish, making it ideal for selling the service of clearing or resetting the 2001 / 2003 RAV4 ECM.



This includes the code for programming the chip and general instructions. Programmer and clip are not included. Please note that this package is intended for technical personnel.

SOIC-8 Clips, "Pomona" brand, can be obtained from Digikey.com in the link below. While the clip pictured in that link is for an SOIC-28, it is for representation only, as the part number in that page is for the SOIC-8.

Because a wiring harness is needed to use the clip, you may construct your own. It is not difficult, but you may also obtain complete assembled kits from several sources, like the one shown below.

Lastly, you will need a serial EEPROM programmer to read/write the EEPROM chips. While there are both expensive and non-expensive units available, what is really important is that such unit is able to work with the target device or devices (EEPROMs). Below are two examples of good programmers.

Note: This is for vehicles WITHOUT a separated immobilizer module or immobox. The illustrations above are for tools or accessories needed, but are not included. This is a download of the needed file for writing the EEPROM. In this model, you WILL NEED to bridge the crystal oscillator to read or write the EEPROM in circuit.

This is an INSTANT download. As soon as purchased, the download will be available from your account on this store.
