Activating components / functions, EMS 2000
- Ignition on.
Activate components / functions by clicking the VCT 2000 symbol.
For information about the different activation's see Description of activations Description Of Activations.

Communication fault
Communication fault
Communication fault
Communication has been interrupted for one of the following reasons:
- The ignition is switched off
- VCT2000 disconnected from the data link connector (DLC)
- VCT2000 disconnected from the VIDA cart
- Communication problems in VIDA application or in car.
- No voltage in the data link connector (DLC).
Check therefore:
- That the control module power supply and ground terminal are fault-free.
- That the fuse for the data link connector (DLC) is intact.
- that the ignition is on
- that the battery voltage (system voltage) is normal (approximately 12 V).
If necessary a battery charger can be connected during the test.
For information about charge currents and the battery, see: Battery, charging Battery, Charging
- that VCT2000 is correctly connected to the VIDA cart and the data link connector (DLC)
- that VCT2000 and the wiring is fault-free.
Other information
- For information about fuse and terminal numbers, see the relevant Wiring Diagram.
Try to establish communication again or exit reading off diagnostic trouble codes (DTCs). Depending on the communication fault, select one of the following options.
1. Try again
2. Fault-trace more comprehensively for the communication problem that has occurred
3. Exit fault-tracing / Read off from the next system.

Checking communication errors car model S40 (-04) / V40
Hint: Test the communication with another corresponding vehicle to decide if the malfunction is in the vehicle or in VIDA/VCT/cable harness. If the communication works on another vehicle, the malfunction is in the vehicle.
Hint: For current information about each circuit and signals, see wiring diagram and signal description for each system.
Diagnostic outlet
- Check the voltage feed to diagnostic outlet #16. The voltage shall match battery voltage.
- Check the cable for power ground and signal ground to diagnostic outlet #4 and #5.
Hint: When VCT2000 is connected to the diagnostic outlet (is supplied with voltage), the indicator diode shall be activated with a green light. Then the indicator diode flashes quickly when communication takes place with a control module. In case of certain internal malfunctions on VCT2000 the indicator diode is activated with a red light!
Communication cables k-line
- Check the communication cables between diagnostic outlet #7 and connected control modules for open circuit, short-circuit to ground and short-circuit to voltage.
Communication cable for cruise control as own system (not integrated)
- Check the communication cable between diagnostic outlet #13 and cruise control for open circuit, short-circuit to ground and short-circuit to voltage according to references above.
Communication cable for engine management system Fenix 5.1 and diesel (not Lucas)
- Check the communication cables between diagnostic outlet #11/#15 and engine control module (ECM) for open circuit, short-circuit to ground and short-circuit to voltage according to references above.
Control modules
- Check that the control module's voltage feed and ground connection are trouble-free.
VCT2000 and cable harness
- Connect VCT2000 to the vehicle so that it is supplied with voltage. Test VCT2000 by selecting the system's self-test and VCT Test in the VIDA main menu. If any malfunction is found according to the test, first replace the cable harness then the VCT2000, if the test still indicates a malfunction.
- If no malfunctions were found after troubleshooting according to above, try with a new cable harness and/or new VCT2000.
VIDA
- If no malfunctions were found after troubleshooting according to above, try performing a complete system reset of VIDA.
