Purpose of the System
The purpose of the DISplus is to meet the challenges for present and future generation BMW group vehicles.
The functions of the DISplus that are
- Diagnosis Program
- Measurement Techniques
- Remote Controller for the SSS to perform Coding Individualization and Programming
The DISplus has Network capability and allows for any necessary upgrades in the future to keep up with the vehicle technology to come.
Scheme 9
Monitor
The DISplus uses a 15" TFT (Thin Film Transistor) monitor. It has a pressure sensitive touch screen controller to direct the curser movement.
The monitor is attached to the DISplus by a 15" cable that allows it to be used either on the swivel stand or remotely, e.g. inside of a vehicle.

Main Power Switch
The main power switch is located in the upper right hand side, at the rear of the DISplus.
The main switch is turned on first, before turning the DISplus on from the front panel. The System Status LED on the front panel should illuminate amber when the main power has been turned on.
Circuit breakers are located below the DISplus computer. If the unit fails to power-up, check the reset of the circuit breakers before calling for service.

Scheme 13
After the main power switch has been turned on, the DISplus is powered up by pressing the on/off button on the front panel.
During power up, LED 2 will illuminate. When the process is complete, the System Status LED changes from amber to green.
The fault indicator, LED 3, illuminates amber when there is a fault with the DISplus.
Scheme 14
DVD and 3.5" Floppy Drive
The DVD and Floppy drives are located behind a door on the right side of the unit.
The Floppy drive is used for the boot-up disk when loading the Diagnosis Program.
The DVD drive is used to load the Basis and Program CDs for Diagnosis.
The TIS CD is also loaded in the DVD drive and remains in the drive for the computer to access during TIS operation.
Scheme 15
RF Access Point
The access point is the transfer device between the hardwired LAN network and the radio frequency assisted LAN.
The DISplus is connected to the access point via a network LAN cable. The access point then communicates with the Diagnostic Head using a radio frequency LAN link.
Scheme 16
LAN (Local Area Network) Connection
The LAN connection has the appearance of a large phone receptacle. It provides the connection for the DISplus to the Ethernet wiring for the Service Department Network.
Scheme 17
TD (RPM input) Cable
TD is a processed engine RPM signal. The TD input cable is used for specific test modules or preset measurements that require a hard wired RPM input for measurement functions.
Scheme 18
Multi-Function Test Cable-MFK#1 (two cable ends)
MFK 1 is used to measure
- Voltage - up to 50 Volts
- Current - up to 2 Amps
- Resistance
- Diode Testing
- Frequency
- Period
- Duty Cycle
- Pulse Duration
- Oscilloscope Measurements
Scheme 19
Multi-Function Test Cable-MFK #2 (Four cable ends)
MFK 2 is used to measure
- Voltage - up to 500 Volts
- Frequency
- Period
- Duty Cycle
- Pulse Duration
- Oscilloscope Measurements
Scheme 20
Both MFK 1 and MFK 2 can be used for signal outputs from the stimulate output function of the multimeter.
On MFK 2, the two large cable ends are for input only (measuring) and the two small ends are for the Stimulate Output function. MFK 1 's leads are for both measuring and stimulation.
Both large positive cable ends of MFK 1 and MFK 2 include a button used to hold the measured value on the display screen.
Scheme 21
Trigger Clip (inductive)
The trigger clip is used when testing ignition or fuel injection systems to establish engine firing order.
Scheme 22
50 and 1000 Amp Inductive Probes
The Amp probes measure AC and DC current. They are self calibrating inductive pickups.
Scheme 23
Temperature Sensor
The long temperature probe measures the temperature of liquids and gasses. The measurement range is from -20°C to 200°C.
Scheme 24
Pressure Sensor
The Pressure Sensor measures from 0 to 25 bar. There are two pressure inputs to the measuring unit that permit two different pressures to be measured simultaneously if two sensors are used.
