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

  A: The necessary first step for performing Engine Control Module programming remotely includes disconnecting the ignition and connecting a Tech 2 to the data link connector. The first step entails activating the ignition without starting the engine followed by complete deactivation of all vehicle accessories. Access Service Programming on the Tech 2 by selecting it on the menu then activate the IEEE 1473.1 passcode entry by providing necessary vehicle details. Begin by selecting the module type for programming and the programming method before verifying that the displayed VIN matches the actual vehicle VIN; if not matching then note the actual VIN and make changes through the Techline terminal. Service Programming should be exited to turn off the Tech 2 and disconnect it from the automotive system. Connect the Tech 2 to the Techline terminal followed by selecting Service Programming and verifying Tech 2 as the active tool. Start by choosing the programming type before checking and possibly adjusting the VIN then select the module type and programming type among Normal updates VCI if VIN is unknown and Reconfigure if changing tire size. Begin the new calibration download process on the Tech 2 by choosing Reprog after verifying all the connections are secure and selecting the correct calibration file. After completing the download process disable the Tech 2 before removing its connection to the Techline terminal and reconnecting it to the DLC interface. Switch on the Tech 2 device and the ignition system with no engine power while choosing Service Programming function. Avoid switching off your ignition since interrupted or unsuccessful programming requires you to check the security of all PCM and DLC connections as well as update Techline software before attempting to reprogram the control module. The replacement of the control module should be conducted when programming is unsuccessful. Less than one meter is required to perform the programming task. Exit Service Programming after completing the download. To complete the procedure finish the ignition for 30 seconds followed by turning off the Tech 2 and execute the CKP System Variation Learn. Then reset the GM Oil Life System and do the Inspection/Maintenance (I/M) Set and program the Theft Deterrent System Components if you replaced any control modules.
