• Q: What are the guidelines and requirements for reprogramming the Engine Control Module on 2005 Toyota MR2 Spyder?

  A: All Toyota/Scion and Lexus vehicles produced from 2001 up to 2007 contain flash-reprogrammable Powertrain Control Modules (PCM) in their systems and technicians should limit their reprogramming to scenarios when Technical Service Bulletins or Service Campaigns give specific instructions. Reprogramming procedures for flash memory use authorized Toyota/Lexus factory tools as well as Vetronix Mastertech devices alongside J2534 Compatible vehicle interfaces that Toyota authenticated and accepted. ECM reprogramming functionality becomes available through genuine Toyota factory scantool software operating from the mentioned scantools but Software version specifications exist in Technical Service Bulletin/Service Communication documents. Customers can obtain the Toyota/Lexus factory scantool and authentic factory software program cards from SPX Corp by contacting (800) 933-8335 for P/N 01001271 factory scantool with software card or P/N 01002593-005 stand-alone software card which comes with the latest production software at purchase time.
