2002 Chevrolet Malibu Parts Questions & Experts Answers

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

  A: A correct remote programming sequence for the Engine Control Module starts by switching OFF ignition and then connecting the Tech 2 to the data link connector (DLC). Start by activating ignition power while keeping the engine engine off along with shutting down all vehicle accessories. Service Programming should be selected within the Tech 2 interface before step-by-step vehicle identification is required. First choose the module type to be programmed and its programming type at the display while inspecting that the displayed VIN matches the actual VIN; correct the VIN at the Techline terminal if both values do not match exactly. Service Programming needs to be exited and the Tech 2 power switched off while disconnecting the device from the vehicle. The next step is to reattach the Tech 2 to the Techline terminal where you should select Service Programming followed by choosing Tech 2 as the operational tool. During the procedure check the vehicle's programming type while verifying the VIN for accuracy before determining the module type alongside the programming type selection which may be Normal for calibration updates, Vehicle Configuration Index (VCI) without VIN details or Reconfigure for tire size modifications. Select the suitable calibration file and double-check the mounting connections before initiating the download process by selecting Reprog on the Tech 2. The download process completes when you turn off the Tech 2 device while disconnecting it from Techline terminals to afterward reattach them to the DLC port. Use the ON/OFF switch on the Tech 2 system to activate it and the ignition system while the engine remains in an OFF position before starting the Service Programming process. Checking all PCM and DLC connections and updating Techline software stands as essential before reprogramming a control module following an interrupted procedure that requires keeping the ignition system on. The control module should be replaced after programming fails to complete successfully. Finally, leave the Service Programming mode after completing the download process. To complete the process disable the ignition for 30 seconds then switch off the Tech 2. Perform the CKP System Variation Learn Procedure then run Inspection/Maintenance (I/M) Complete System Set Procedure before Programming Theft Deterrent System Components and resetting the GM Oil Life System if a control module was replaced.
