• Q: How to perform remote programming of the Engine Control Module on 2002 Buick Regal?

  A: A necessary step before starting remote programming on the Engine Control Module involves turning off ignition and connecting the Tech 2 to the data link connector (DLC). The first step begins with ignition activation when the engine remains powered down and all vehicle accessories must be switched off. During the procedure select Service Programming in the Tech 2 software to identify the vehicle information as displayed. Start by selecting the module for programming as well as the programming type from the menu and verify the displayed VIN matches the actual vehicle VIN using the Techline terminal. Note any inconsistencies between the two VINs before making a correction. The programming sequence ends by exiting Service Programming while you turn OFF the Tech 2 and disconnect its cords from the vehicle. Connect the Tech 2 to its Techline terminal after which select Service Programming again with the correct tool selection set to Tech 2. Select the programming type for a second time while making necessary VIN corrections if required. The application type includes Normal for calibrations updates and Reconfigure for tire size changes while VCI stands for Vehicle Configuration Index when the VIN is missing.

The procedure requires turning OFF the Tech 2 before disconnecting its cable from the Techline terminal and then reconnecting it to the device link connector. Users should activate the Tech 2 and start the ignition switch when the engine remains off before proceeding with Service Programming selection. Reprogramming the control module requires ensuring all PCM and DLC connections are secure along with an updated Techline software before another attempt.
