Immobilizer reset. This
is a virgin dump for the ECM of the 2001 - 2003 Toyota
RAV4.
What is this? - This is the software (code) that
goes inside the immobilizer chip, located in the ECM, for resetting the
Immobilizer system (security), so the vehicle accepts your current, used or
new keys. Once you write this code in the immonilizer EEPROM chip (25080), it
will be in auto reguster mode, where it will register the keys you have for
starting the engine. This file will be instantly available for downloading after
the purchase is made.
Will this fix the transmission problems of these
models? - No, this will make the ecm ready to start with your
keys if it was repaired, remanufactured, sourced from a recycler,
junkyard or any other source like eBay. Instructions are included in the
download.
For using this, you will need an EEPROM programmer and an SMD
SOIC-8 clip for writing the EEPROM either in-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 the Pomona Company, with a cost around $15.
NOTE: If you are
going to do only one vehicle or if you don't have the hardware or tools needed
as explained in this page, then we have a much more economical way. We are also
offering the chip already programmed, so you just uninstall the old chip and
install our chip in its place and your RAV4 will be ready to run. If interested
in this alternative, you will find the product in the link below:
The
clip is known as an SMD SOIC-8 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 (pins) chip and
reprogram it by writing the included code and then you are ready to
reinstall the ECM back in your vehicle and drive it with your existing old,
used 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 purposes only, as the part number in that page is for the SOIC-8.
POMONA SOIC-8 SMD Clip 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.
SOIC-8 Assembled Kit Lastly, you will need a
serial EEPROM programmer to read/write the EEPROM chips with the file you will
download from here. 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 with
