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

  A: The procedure for remote Engine Control Module programming starts by turning off ignition and connecting the Tech 2 tool to the data link connector (DLC). Start the ignition system then pause the engine operation while making sure every accessory remains deactivated. Starting with Tech 2 the Service Programming function must be selected followed by entering the required vehicle data. Determine the module type for programming followed by the programming selection then compare the VIN displayed to the actual vehicle VIN while documenting any displayed mismatch to update at Techline. Press the exit button to terminate Service Programming and then disable the Tech 2 followed by disconnecting its cables from the vehicle. Reconnect the Tech 2 to the Techline terminal followed by selecting Service Programming again before confirming the tool is Tech 2. Select the programming type and module for the operation while choosing between Normal for calibration updating or Vehicle configuration index when the VIN is unknown or Reconfigure to update tire specifications. Click the correct calibration file then verify all cables are secure before starting the download procedure with Reprog. The programming download process finishes before you switch OFF the Tech 2 tool and remove it from the Techline interface terminal. After the Tech 2 connection to the DLC, turn ON power and start the ignition with the engine OFF under the Service Programming menu. It is essential to avoid shutting off the ignition when control module programming fails or gets interrupted because all PCM and DLC connections must be checked along with verifying that the Techline software is updated before continuing with control module reprogramming. The control module needs replacement if programming fails to complete successfully. Select Program followed by a software download exit of Service Programming then wait for thirty seconds and disconnect the Tech 2. The replacement of a control module requires execution of the CKP System Variation Learn Procedure followed by GM Oil Life System reset and I/M Set Completion at Maintenance and Lubrication and final programming of Theft Deterrent System Components in Theft Deterrent.
