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

  A: The first step to perform remote programming of the Engine Control Module involves turning OFF the ignition while installing the Tech 2 connector to the data link connector (DLC). Start the ignition while keeping the engine at rest and disable all vehicle accessory features. Open the Service Programming menu on the Tech 2 tool before you identify the vehicle information following the prompts. Follow these steps by choosing the equipped module followed by selecting the programming type then double-check the displayed VIN matches the one on the vehicle; if not equal write down the actual VIN while correcting it on the Techline terminal for future reference. Exit Service Programming then deactivate the Tech 2 while disconnecting it from the vehicle. To reestablish connection between the Tech 2 and Techline terminal select Service Programming before choosing Tech 2 as the tool option. The technician should verify the VIN again before making a selection among Normal programming for updates, Vehicle Configuration Index for VINless operations or Reconfigure for fire size and axle ratio modifications. Choose the required calibration file before making sure all connections are tight and then start the download by clicking the Reprog button. The process of downloading ends when you disable the Tech 2 unit while removing it from the Techline terminal. Connect the Tech 2 to the DLC and activate the device before starting the ignition without starting the engine. Then choose Service Programming from the menu. The programming of control modules requires all PCM and DLC connections to be stable along with recent updates on Techline operating software before trying another attempt at reprogramming the module. Turn off the ignition only when a programming cycle finishes without disruptions. A failed replacement of the control module calls for replacing the component. Complete the download process by choosing Program then leaving Service Programming before waiting for 30 seconds with the ignition off and finally powering down the Tech 2. The replacement of any control module requires the execution of the CKP System Variation Learn Procedure followed by reset of GM Oil Life System and Inspection/Maintenance (I/M) Set Procedure completion along with Theft Deterrent System Components programming.
