V50 L5-2.4L VIN 39 B5244S7 (2005)
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 Precautions/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.
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
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.

Selecting car model
Select car model to obtain relevant troubleshooting information.
Select one of the following model alternatives
1. S40 (04-) / V50.
2. V70 (00-), V70 XC (01-) / XC70, S60, S80 and XC90.
3. V70 (-00), V70 XC and S70 / C70.

1 - car model S40 (04-) / V50
2 - car model V70 (00-), V70 XC (01-) / XC70, S60, S80 and XC90
3 - car model V70 (-00), V70 XC and S70/C70
4 - Checking communication errors car model S40 (-04) / V40
Checking communication errors, car model S40 (04-) / V50
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.
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!
