What steps should be taken to set up for programming the Engine Control Module (EEPROM) on Chevrolet Express 3500?

Every programming operation on the vcm (EEPROM) needs a fully charged battery while the ignition remains on along with a solid data link connector (DLC). You must use a current model techline terminal that implements vcm programming according to the user manual guidelines. Attempt vcm programming once again only after ensuring all connections are correct plus checking for the latest itcs terminal and equipment software version; repeat this process two times before deciding to replace the vcm. The passlock reprogramming procedure follows the ckp system variation learn procedure during the execution. A functional check must be conducted by running the powertrain on-board diagnostic (OBD) system check.

What does the service of the engine control module (ECM) typically involve on Chevrolet Express 3500?

The powertrain control module (PCM) service requires the option between replacing the pcm unit or programming its electrically erasable programmable read-only memory (EEPROM). A proper inspection must be performed on the pcm to verify the right replacement part. Perform the installation of the new service pcm only after confirming that it is the faulty unit. Turn off the ignition prior to disconnecting or reconnecting power to the pcm because this process includes working with battery cables, pcm pigtail, pcm Fuse and jumper cables. Proceed to inspect pcm module connector gaskets for correct installation because they serve to block contaminant penetration through the pcm connector surfaces. Also remove all debris from pcm connector contact points. The programming process needs to be completed for the new pcm. Start the pcm removal process by dismantling the air cleaner before disconnecting both the Battery Cable and harness connections of the pcm while keeping away from pins and soldered sections to stop electrostatic discharge (ESD) damage. Pull the spring latch of the pcm while lifting it out of the mounting tray then extracting it through the engine compartment. Install the pcm into the mounting tray by fastening the spring latch then connect all pcm connectors before securing their end fasteners to 8 n.m (71 lb in). Restablish the black Battery Cable while reinstalling the air cleaner assembly. The new pcm needs programming through the service programming system (SPS) procedures during installation.
