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 See: Starting and Charging/Battery/Service and Repair/Procedures/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.
Which alternative is requested?
------------------------
1 - Resetting the service reminder lamp (SRL)
2 - Checking communication problems
3 - FAILED

Checking communication problems
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.
