2005 Toyota Prius Engine Control Module Parts Q&A

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

  A: A hand-held tester must be used to enter the Vehicle Identification Number (VIN) which contains 17 alphanumeric digits. The registration process demands step-by-step instructions for entering the VIN followed by reading its value before writing it. The tester provides two sets of buttons for input where you can move the cursor with up, down, right, left and use the numerical buttons 0 through 9. The tester controls movement with right and left buttons and accepts alphabetic selections through up and down buttons while each numeric value requires selection using the matching numerical button. Users should navigate to the incorrect character using the right or left buttons to select the correct version of that character after correcting errors during input. The next step after data entry involves verifying the VIN for correctness followed by pushing the enter button to complete the process. The VIN will be accessible through the hand-held tester while using the same method to transfer the VIN to the ECM through the hand-held tester.
