2005 Toyota Sienna Parts Questions & Experts Answers

• Q: How to register the Identification Number (VIN) into the replaced Engine Control Module (ECM) on 2005 Toyota Sienna?

  A: A hand-held tester enables the registration of a VIN into the replaced Engine Control Module (ECM) through the input of the 17-digit alphanumeric Vehicle Identification Number (VIN). The registration procedure consists of three fundamental sections: Input Instructions as well as Read VIN and Write VIN. During Input Instructions the hand-held tester requires full operation guidance which uses the UP, DOWN, RIGHT, LEFT arrow keys and 0-9 numerical buttons for entering the VIN. To access different screen options on the tester users can utilize the RIGHT and LEFT buttons while selection between alpha and numeric keys is performed via UP and DOWN buttons and the corresponding numeric keys provide further options. Users should place the cursor on the desired character with the RIGHT or LEFT button followed by selecting the right character through either the UP/DOWN or numerical buttons. Proceed to finalize the input operation by pressing ENTER after confirming that the entered VIN matches the vehicle VIN. The hand-held tester allows reading the VIN stored in the ECM while the writing process for VIN into the ECM occurs through hand-held tester operations.
