  Q: What are the guidelines and requirements for reprogramming the Engine Control Module on Toyota Echo?

  A:

  Starting with 2001 model year vehicles until Toyota/Scion and Lexus vehicles got full implementation in 2007, all Powertrain Control Modules have the capability to receive flash reprogramming functions. These reprogramming sessions must follow Technical Service Bulletin and Service Campaign instructions. You can execute flash reprogramming of Toyota vehicles by using either the Toyota factory scantool or Vetronix Mastertech or any J2534 Compatible Vehicle Interface which Toyota has validated. The ECM reprogramming capabilities become available when using authentic Toyota factory scantool software that operates on the noted scantools while specific software versions follow the guidance mentioned in relevant TSB/SC documents. SPX Corp supports the purchase of Toyota/Lexus factory scantools and authentic factory software program cards by dialing (800) 933-8335 to obtain P/N 01001271 for the complete scantool setup consisting of both hardware and software card or P/N 01002593-005 for the standalone software card which includes the latest production version software. Vehicle recalibration using scantools demands Personal Computer execution of Microsoft Windows 2000 or Windows XP alongside a Toyota Diagnostic Tester or Vetronix Mastertech Scantool which contains Toyota factory software and a Toyota/Lexus factory scantool program card as well as a PC Interface Cable (P/N 01001090) to move PC data to the scantool and Calibration CD (00456-REPRG-001). Toyota authorized J2534-1 interfaces can reprogram ECMs that scantools can modify through the use of Calibration Update Wizard software provided on the Calibration CD set (00456-REPRG-001) and any Personal Computer operating Microsoft Windows 2000 or XP or later versions. Toyota demands users to employ solely validated interface devices presented on their lists because these tools have received thorough testing and completing validation for Toyota, Scion, and Lexus models. Toyota performed testing on every listed device firmware DLL and API combination and stresses that any modifications to the J2534 hardware or software framework could decrease system reprogramming capabilities. The approved diagnostic tools include Drew Technologies CarDAQ Plus (01.08.06 / 01.08.06 / 04.04) and Actia Pass Thru+ XS (02.01 / 02.01 / 04.04) as well as 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 / 04. The Calibration CD supports all scattered scantools and J2534 interfaces and includes vehicle calibration files and TSBs alongside Windows PC software for the Calibration Update Wizard with operating instructions which can be purchased through the Toyota Material Distribution Center with P/N 00456-REPRG-001. A vehicle controller faces permanent damage during flash reprogramming so all processes must remain uninterrupted by maintaining devices connected to PCs awake at all times. Before any vehicle work starts readers must thoroughly study the materials along with following all instructions since the content serves only qualified automobile technicians.
