2002 Cadillac Eldorado Parts Questions & Experts Answers

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

  A: Begin the Engine Control Module remote programming by turning off the ignition while connecting the tech 2(TM) to the data link connector (DLC) of the vehicle. Start the ignition system while the motor remains inactive and verify that all accessories stay deactivated. Begin by opening the service programming section on the tech 2(TM) tool followed by the request info page and then provide the vehicle information data when asked for. The first step involves selecting the module type for programming along with the programming type then verifying that the displayed vin matches the actual vehicle vin before noting any discrepant information at the techline terminal. Exit the service programming interface then disable the tech 2(TM) while disconnecting it from the vehicle. The following steps should be followed: connect the tech 2(TM) to the techline terminal and select service programming before choosing tech 2(TM) as the tool. Verify the vin before selecting the desired module type and programming type which may be normal, vehicle configuration index (VCI), or reconfigure. Start the download procedure by using reprog after making sure all wires are properly connected to the appropriate calibration file. After the download process completes you should disable the tech 2(TM) while removing it from the techline terminal. Plug the tech 2(TM) to the dlc and turn it on while leaving the engine ignition off. Maintain the ignition on and avoid powering it off when service programming experiences interruptions or failures during reprogramming of the control module while verifying correct connections of all pcm and dlc modules along with updated techline operating software. Attempt reprogramming one more time before moving forward to control module replacement (Powertrain Control Module (PCM)). Program selection completes after the download before you choose to exit service programming. Transfer the ignition power off for thirty seconds before exiting the tech 2(TM). Follow the pcm replacement with programming and complete the procedures for resetting fluid life indexes and learning the theft deterrent password and crankshaft variation then perform tp sensor learn and iac valve learn and i/m system status reset.
