XC90 2.5T AWD L5-2.5L Turbo VIN 59 B5254T2 (2003)
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).
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/Technician Safety
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.
Which alternative is requested?
1 - Checking brake light switch adjustment
2 - Checking communication errors
3 - Exit fault-tracing / Read off from the next system
Checking communication errors
Checking communication errors, car model V70 (00-), V70 XC (01-) / XC70, S60, S80 and XC90
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.
Different speed on the CAN-communication can lead to problems
Volvo's vehicles have different speed of communication on the high-speed part of the CAN-network (HS-CAN), depending on model year.
Model year -2004 communicates with 250 kbit/s.
Model year 2005- communicates with 500 kbit/s.
Due to this, it is very important to specify correct vehicle profile before any communication is started with the vehicle's HS-CAN. This is normally done
by pressing on " Retrieve VIN" or by manually specifying vehicle parameters under "Vehicle profile".
If the wrong model year has been selected, it may lead to blocking of the CAN-net, diagnostic trouble codes being stored in several control modules or
missing response from control modules at continued communication. The following control modules may be affected by this problem:
