- MoDiC software loading
- Charging the MoDiC batteries
- Printer connection link for the MoDiC while docked in the charging station.
The charger/docking contains the following features
Scheme 554
The floppy and CD ROM drives are used to update the MoDiC software and to down load programs. The MoDiC can only gain access to the drives when it is docked on the station.
Battery Charging
The two battery compartments on the docking station are for charging spare batteries.
The status LED on the side of the docking station indicate the state of charge of the batteries being charged.
The batteries in the MoDiC will also be charged while it is docked on the station.
Scheme 555
The status LED indicators provide the following information
Scheme 556
Printer Interface
The Docking Station printer interface connections are located on the underside of the unit.
These parallel printer connectors are for connecting the MoDiC docking station to the DIS printer.
A locally purchased Male/Male 25 pin parallel printer cable will be required. Connect as shown.
Scheme 557
Scheme 558
The diagnostic head is the link between the vehicle's electronic systems and the MoDiC tester.
The head is a self-contained computer that receives its power from the diagnostic socket when the head is plugged in.
The diagnostic head has 3 MB of data storage and a PCMCIA card for storing and transmitting data to the MoDiC.
The size of the diagnostic head has been kept small so that it can fit under the hood when it is closed. Future plans call for the head to be used as a flight recorder that can be attached to the vehicle and record data on a suspect system while the vehicle is being driven
Data from the diagnostic head can be transmitted to the MoDiC either by Radio Frequency (RF) or by a hard wire cable link. The RF transmitting range is approximately 950 feet and the hardwire cable is 25 feet long.
The diagnostic head has four connectors
- Bottom edge: Two single connectors (red/black) used for signal recording for future usage and one multi-pin connector for the 20 pin diagnostic socket or OBD II DLC.
- Top edge: COM connector for 25' wire link between Head and MoDiC.
Scheme 559
Scheme 560
The diagnostic head contains a status LED and a data recorder button (future use) on the side.
If the flight recorder button is pressed, the head goes into the record mode and communication between the head and the MoDiC is interrupted (make sure button is in the off position).
Connect the head with the 20 pin connector to the vehicle with the ignition key off. Switch ignition on and watch the Head Status LED. The status LED provides the following information in regards to the diagnostic head operation
Scheme 561
| LED DISPLAY | INDICATION |
|---|---|
| Off | No power supply to the diagnostic head |
| Green - short flashes | Diagnostic head establishing the communication link |
| Green - long flashes | No connection possible |
| Green - steady | Diagnostic head communication link established |
| Orange - slow flashing | Faulted connection |
| Orange - rapid flashing | Temperature limit of Diagnostic head exceeded |
FLIGHT RECORDER
Temperature Monitoring
If the temperature threshold of the diagnostic head is reached, a warning display will appear on the MoDiC screen. The diagnostic procedure should be terminated and the head allowed to cool down.
If the temperature threshold is exceeded, the diagnostic head will switch itself off and the connection to the MoDiC will be terminated. Once the head has cooled down, the diagnostic link can be reestablished.
Serial Interface Cable
25 feet cable for a hard wire connection between the diagnostic head and the MoDiC.
Scheme 562
DC Power Supply
External power supply cable for the MoDiC/Docking Station.
Allows vehicle 12 volt power supply to power the MoDiC or docking station.
Scheme 563
Multi-Function Cable (MFK)
MFK 1 and MFK 2 measurement cables used with the MoDiC's measurement system. Both cables are 2 meters long.
Measuring parameters for the cables are similar to the DIS tester's MFK 1 and MFK 2 MFK 1

Scheme 565
Suspend Mode
The MoDiC will switch to the suspend mode after a period of time when no activity has taken place.
The suspend mode is a power saving mode that is designed to save battery power. The MoDiC switches to the suspend mode in three steps as follows
Stage 1 (doze mode): The computer's clock pulse frequency is reduced to save power
Stage 2 (sleep mode): The hard disc is switched to the economy mode to save power.
Stage 3 (suspend mode): All internal components are switched off, but the content of the working memory is saved.
Any of the power-economy stages will be terminated if the touch screen is pressed. The suspend mode can be manually activated or deactivated by pressing the suspend mode button in the control panel.
Detailed Operation Instructions
Refer to the Handbook included with the MoDiC for in-depth setup, initial boot-up and cleaning/maintenance procedures.
Measurement System
The Measurement system is an integral part of the test procedure. It displays automatically when needed by the test schedule.
In E46 diagnosis, measurements are no longer phrased as
.... "connector X 10 pin 1 to connector X 20 pin 2."
Measurement instructions are now provided in the bottom right dialogue box as follows
Voltage Measurement
MFK 1 (+) ON (circuit name)
MFK 1 (-) ON ground
All measurements now relate to circuit name acronyms that are "hot spot" activated (if needed). Nominal values are displayed with the actual measured display. Simply answer the question the system provides in response to the measured value.
Scheme 566
If you are using a DVOM for measuring the values in place of the DIS/MoDiC MFK leads, you can enter the measured values into the system and follow the test plan as follows
- Press the measurement system value display bar to bring up a "key pad".
- Enter the measured value into the key pad and press the enter button. The DIS /MoDiC uses the entered values to continue with the test plan.
Scheme 567
Before diagnosis is terminated, a dialogue box reminds you to print the diagnosis report.
The dialogue box offers the following options
- "Terminate" ends diagnosis without printing the diagnosis report.
- "Diagnosis Report" prints the report before terminating.
If you forget to print the report before terminating diagnosis, it will be stored and can be printed by selecting "Stored Diagnosis Report" from the Print menu.
Control Unit Functions
Troubleshooting information is also available in the form of Control Module ID, status lists, component activation, read and clear fault memory by pressing the Control Unit functions button.
Only control modules identified during the short test can perform control unit functions
