The lack of knowledge of multiplex technology among mechanics is a cause for concern, and is therefore a threat to the successful introduction of multiplex.
Today, a majority of Electronic Control Modules replaced at maintenance and/or service occasions are in fact fault free. A significant reason for this is that mechanics replaces wrong parts due to lack of understanding of how the electronic system works.
With multiplex, this problem can increase an order of magnitude - if it is not recognised. The need for better training and education of maintenance personnel increases rapidly.
Multimedia training courses in multiplex technology (general and vehicle specific) is a good opportunity to meet this need. Such a training course is as a proposal integrated in a PC/CD-ROM based Diagnostic tool.
With this approach, the maintenance personnel can receive a high class, Just-In-Time, and enjoyable training program.
