Programmable Module Installation
Programmable Module Installation (PMI) method is used when a new programmable module is installed. NGS tester automatically obtains any valuable module option content information from old module during vehicle ID routine that runs when NGS tester is initially connected to vehicle. It is important to connect NGS tester to DLC and allow it to identify the vehicle and obtain configuration data prior to removing any module.
REMOVAL & INSTALLATION
| CAUTION | Electronic modules are sensitive to static electrical charges. Proper grounding of technician and workplace is essential to prevent damage. Prior to removal of modules, it is necessary to upload module configuration information to New Generation Star (NGS) tester. This information needs to be downloaded into new module once installed. See MODULE CONFIGURATION under PROGRAMMING. |
Note. When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
