  Q: What are the guidelines and requirements for reprogramming the Engine Control Module on Scion xA?

  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. The vehicle recalculation process using a scantool requires a Microsoft Windows 2000 or Windows XP operating PC and a Toyota Diagnostic Tester or Vetronix Mastertech Scantool equipped with Toyota factory software together with a Toyota/Lexus factory scantool program card and a PC Interface Cable (P/N 01001090) for data transfer and the Calibration CD (00456-REPRG-001). The reprogramming of ECMs with scantools can be accomplished through a Toyota validated J2534-1 interface system that needs a verified J2534 interface and Toyota Calibration Update Wizard from Calibration CD (00456-REPRG-001) alongside Personal Computer running Microsoft Windows 2000/XP or later. Toyota mandates vehicle owners to use interface tools from its validated list since these tools have undergone thorough testing on Toyota, Scion, and Lexus automobiles. The validated J2534 devices consist of Drew Technologies CarDAQ Plus (01.08.06 / 01.08.06 / 04.04) and Actia PassThru+ XS (02.01 / 02.01 / 04.04) along with Vetronix Corporation ES6510 Flasher (06.12 / 04.23 / 04.04), EASE Diagnostics Universal Reprogrammer (JPI1_11b / 1.3.0.13 / 04.04), Snap-On Pass Thru Pro (02.01 / 02.01 / The firmware and DLL versions used for original validation can be replaced by manufacturers of the devices. For additional information regarding J2534 devices you should contact the vendors directly. The Calibration CD can be purchased through the Toyota Material Distribution Center by using P/N 00456-REPRG-001 and includes the following contents: vehicle calibration files, TSBs, a Windows PC-based Calibration Update Wizard application and use instructions for mentioned scantools and J2534 interfaces. The flash reprogramming operation threatens to initiate long-lasting damage to the vehicle controller due to three vital requirements: avoid interruption during the process and prevent disconnection of any device and disabled power management on PCs. Technical automobile professionals should use the provided information but must study all material contents before vehicle work to guarantee the vehicle stays intact with safe service procedures.
