How do I know if my 2001-2003 Toyota Rav4 has immobilizer (immo)? If in doubt, one way to know if your Rav4 has the immobilizer system or not is by checking the description in the article below: The ECMs without the immobilizer system will NOT need this process. NOTE: The chip file (program) available in the form above is for the 2001-2003 Rav4 models, equipped with the immobilizer system. Get the 2001-2003 Toyota Rav4 Immobilier file for FREE! You may get that specific immobilizer reset file from us ( FREE) in the form below: The reset file is the file that you will need to program (write) to the EEPROM. You may do the programming either in-circuit or off the circuit by using a reset file. At this point, you can go ahead and try programming the chip.įor reprogramming the chip, you will need an EEPROM programmer. The replacement ECM being defective is another possibility.
#PONY EEPROM PROGRAMMER FULL#
If the sync process in the link above does not work, it could be that something was done wrong or went wrong in the process, or could be that the key memory is full (it has a limited capacity for storing key codes). This sync process is described in the article below and while it is for the Toyota Corolla, it is also exactly the same process for the Rav4 and it covers all Toyota models from 1999 all the way to the present. We call it the Toyota synch process and what it does is exactly what its name suggests, synchronizing the immobilizer system data of the new ECM (replacement) with the immobilizer system data of the vehicle.
#PONY EEPROM PROGRAMMER MANUAL#
This applies to either 4WD or 2WD models and to either Automatic or Manual transmission models.īefore programming the ECM, you should know that there is a simple process that car owners can do by themselves to synchronize the immobilizer data of the ECM to the Immobilizer system of the vehicle. In this article, we will cover the removal of the immobilizer EEPROM chip of the 2001-2003 Toyota Rav4 ECM circuit for either replacing or reprogramming it. When you replace your 2001, 2002, or 2003 Toyota RAV4 ECM (engine computer or ECU) with a used or recycled unit, if your vehicle is equipped with an immobilizer system, which is an anti-theft security system, you must reprogram the ECM to work with your existing keys (immobilizer system).
