• Q: How to perform remote programming of the Engine Control Module on 2001 Chevrolet Suburban 1500?

  A: Perform remote programming on the Engine Control Module by beginning with turning off the ignition then connecting the Tech 2 to the data link connector (DLC). The first step requires turning ON the ignition while allowing the engine to remain switched OFF. During the process ensure all vehicle accessories are deactivated. You must access Service Programming on the Tech 2 while following the provided vehicle identification requests. Begin the programming stage by selecting the module type as well as its programming type while checking the displayed VIN against the actual VIN of the vehicle; record the actual VIN for future correction through the Techline terminal. Service Programming must be exited before the Tech 2 is switched OFF while removing the connector from the vehicle. To start connect the Tech 2 to the Techline terminal followed by opening Service Programming and selecting the device as Tech 2. Check the VIN that displays on the screen and make changes if needed before selecting the module type and choosing between Normal programming or Vehicle Configuration Index when the VIN is missing or Reconfigure for tire size modifications. Start by choosing the correct calibration file while verifying all connections are tight before selecting the Reprog command for the download process toward the Tech 2 component. Following the download process users must disable the Tech 2 before detaching it from the Techline terminal and then plug it into the DLC port. Switch ON the Tech 2 while setting the ignition OFF followed by choosing Service Programming from the interface. Before trying to reprogram the control module ensure that all PCM and DLC connections are secure plus both the programming procedure and the techline operating software are up to date. Turning off the ignition during an interrupted or unsuccessful procedure should be avoided. A replacement becomes necessary when programming the control module fails. Users must select the Program option followed by ending the Service Programming interface. After switching OFF the ignition for 30 seconds also follow by turning OFF the Tech 2 then execute the CKP System Variation Learn Procedure followed by the Inspection/Maintenance (I/M) Complete System Set Procedure and Programming Theft Deterrent System Components if a control module was replaced.
