• Q: How to program the Engine Control Module on 2002 Chevrolet Impala?

  A: Obtain the VIN from the vehicle and start programming the Engine Control Module. The Techline terminal enables users to choose Service Programming followed by Tech 2 then select Reprogram ECU and Off-Board Programming Adapter as the programming location. Follow the protocol to connect the control module with the Tech 2 by utilizing off-board programming adapter equipment from the off-board programming adapter kit using appropriate connectors. Start the Service Programming Request Information function on the Tech 2 to exchange signals with the control module before you close the function screen. The Tech 2 requires detachment from the Off-Board Programming Adapter before it should be connected to the Techline terminal for activation. Using the Techline terminal enter the VIN of the vehicle that will accept the control module and a database connection message will appear. Determine the programming nature and pick the suitable calibration file while ensuring all cables remain secure. The Techline terminal presents the summary screen that requires your confirmation before starting the automatic calibration file transfer to the Tech 2. Terminating the Tech 2 download provides the option to detach it from the Techline terminal before connecting it to the Off-Board Programming Adapter. Select Service Programming on the Tech 2. Do not disconnect the Off-Board Programming Adapter unless you complete the programming procedure successfully and all system connections remain secure and the software is updated on Techline. The control module needs replacement if reprogramming fails to execute. Complete the download within Service Programming on the Tech 2 then choose Program and finally disable the off-board programming adapter.
