MoDiC III: Introduction
The MoDiC III is necessary to meet the diagnostic needs of BMW vehicles. It compliments the DISplus as a diagnostic tool that enables the technician to quickly troubleshoot electronic faults and problems with the vehicles.
The advantage of the MoDiC is its mobility. You have the ability to take the tester anywhere in the workshop and to the vehicle. Additionally, the diagnostic head of the MoDiC will have the capabilities of being used as a flight recorder in the future. It can remain connected to the vehicle while it is driven to check for intermittent problems or conditions that only occur while the vehicle is driven.
The objectives used in the development of the MoDiC included:
- Maximum functional efficiency and mobility in the workshop
- Diagnostic procedures similar to the DISplus
- Operation similar to the DISplus
- Basic measurement techniques available
- Integrated TIS function
- Designed for future requirements
- Common Software CD for both the MoDiC and DISplus
The MoDiC is a complete Diagnostic and Information System based on the current DIS tester. The complete MoDiC consists of the following components:
- MoDiC tester
- Charging/Docking Station
- Diagnostic Head
- Diagnostic Cables (measurement cables)
- Diagnostic Interface (serial cable)
- Main/buffer batteries
The MoDiC can be used for diagnosis purposes in several different configurations as follows:
Portable:
- At the vehicle with either the radio frequency (RF) or cable interface
- At the workbench with either the RF or cable interface
Docked on the charger with the RF interface or cable interface
