Programming and Relearning
VEHICLE REPROGRAMMING
Beginning with some 2001 models and expanding to all models by 2007, Toyota/Scion and Lexus vehicles are equipped with flash reprogrammable Powertrain Control Modules (PCM). Reprogramming should only be performed if a Technical Service Bulletin or Service Campaign provides direction to do so.
Flash reprogramming may be accomplished using one of the following methods:
- Toyota/Lexus factory scantool
- Vetronix Mastertech
- J2534 Compatible Vehicle Interface (Toyota validated and approved)
REPROGRAMMING WITH SCANTOOL
Toyota/Scion/Lexus ECMs can be reprogrammed using either the Toyota/Lexus factory scantool, or the Vetronix Mastertech scantool. The ECM reprogramming function is only available with the authentic Toyota factory scantool software which runs on either of the above mentioned scantools. Scantool software version requirements are specified in applicable Technical Service Bulletin (TSB)/Service Communication (SC) documents.
The Toyota/Lexus factory scantool and/or authentic factory software program cards can be purchased through the official Toyota and Lexus Special Service Tool provider, SPX Corp. To order, call (800) 933-8335 and request either:
- P/N 01001271 for the Toyota/Lexus factory scantool including factory software program card
- P/N 01002593-005 for the "stand alone" program card
Program cards are provided with the latest production version software available at time of purchase.
Vehicle recalibration using a scantool requires use of the following:
- Personal Computer running a Microsoft Windows 2000 or Windows XP operating system
- Toyota Diagnostic Tester or Vetronix Mastertech Scantool with Toyota factory software
- Toyota/Lexus factory scantool program card
- PC Interface Cable (P/N 01001090) to transfer data from PC to scantool
- Calibration CD (00456-REPRG-001)
REPROGRAMMING WITH J2534 INTERFACE
Toyota/Scion/Lexus ECMs that can be reprogrammed with a scantool can also be reprogrammed using a Toyota validated J2534-1 interface. Vehicle recalibration requires the use of the following:
- Toyota validated J2534 interface
- Toyota Calibration Update Wizard software (available on calibration CD)
- Personal Computer running Microsoft Windows 2000/XP or later operating system
- Calibration CD (00456-REPRG-001)
Toyota strongly recommends USING ONLY VALIDATED INTERFACE DEVICES that appear on this list.

IMPORTANT NOTICE
It is possible to permanently damage a vehicle controller during the flash reprogramming process. It is especially important to understand that once started, the reprogramming process must not be interrupted, reprogramming devices must not be disconnected and PCs must not be allowed to go into standby, hibernation or similar power management modes. The information provided herein is intended expressly for use by qualified professional automobile technicians. To prevent damage to your customer's vehicle and ensure safe service practice, read these materials completely and thoroughly before servicing the vehicle and be sure to follow all instructions.
