Powertrain Reprogramming

Beginning with some 2001 models and expanding to all models by 2007, Toyota/Scion/Lexus vehicles have flash reprogrammable powertrain ECMs.
Reprogramming is only performed if a Technical Service Bulletin or Service Campaign provides direction to do so. Flash reprogramming can be accomplished using a scantool or a PC and a 'Toyota validated' J2534-1 interface.

Scantool Reprogramming
Toyota/Scion/Lexus ECMs can be reprogrammed using either TIS techstream, Techstream Lite, previous Toyota/Lexus factory Diagnostic Tester, or the Vetronix Mastertech scantool. The ECM reprogramming function is only available with the authentic Toyota factory scantool software which runs on any of the above mentioned scantools. Please reference the following link for more information: TIS Techstream
Tool
The Toyota Diagnostic Tester scantool can be used for all flash reprogrammable Toyota/Scion/Lexus ECMs, 2001 through April 2007. The Diagnostic Tester Scantool is not recommended for service reprogramming operations introduced after April 2007. Please reference the following link for more information: Toyota Diagnostic Tester Scantool / Vetronix Mastertech
