Process Overview
ECU Flash Reprogramming is a 4-step process:
1.
Locate the desired calibration file on TIS (Technical Information System).
Calibration files may be found in two areas:
a.
Search by model and year for a Technical Service Bulletin addressing a specific product issue.
b.
Search by model under the ECU Flash Reprogramming section.
2.
Download the calibration file from TIS to the Diagnostic Tester.
The Calibration Update Wizard (CUW) is an application on TIS which downloads calibration files from TIS to the Diagnostic Tester Program
Card. This step is only required when the calibration file is not currently stored on the Diagnostic Tester Program Card.
3.
Reprogram the vehicle ECU with the Diagnostic Tester.
Diagnostic Tester Software now incorporates a function to update a vehicle's ECU calibration through flash reprogramming.
4.
Confirm successful flash update and affix calibration update sticker.
Modifications to ECU calibration files must be recorded and properly displayed on the vehicle using the calibration update sticker.
