wiTECH 2.0 Programming Guide

Flash programming using wiTECH 2.0 software, connect the Micropod II interface to OBD II / DLC port in the car. wiTECH 2 will start to identify the vehicle based on VIN and the installed components in the vehicle network, which will bring up the network topology.

In this document, we will explain how to do flash programming using wiTECH 2. Once your vehicle's all set up to flash, don't forget to connect the external battery maintainer.  For this test, we have in our programming bay a 2018 Dodge RAM 1500 PICKUP 5.7L HEMI. 

wiTECH 2.0 network topology tree

Once the Micropod II identified in wiTECH 2 click anywhere in the gray box area, it'll bring up the network topology. Click on the tab "All Flashes" at the top bring up the only flash that's available for this car. Right side there's an arrow select that, and it'll bring you to the module flashing screen, where you'll want to click on the consent checkbox. Selecting that you understand that you're flashing will ask you to select a category of why this particular vehicle needs to flash, I choose Service Information/documentation led to re-flash the component. This car has a check engine light that meets a flash so we'll type in the box flash for drivability issue as per Technical Service Bulletin TSB, and you'll click Flash ECU button.
