Checking wiring and terminals See: Testing and Inspection/Component Tests and General Diagnostics/Checking Wiring and Terminals
Continue - Fault-tracing information
Checking communication errors, car model V70 (-00), V70 XC and S70/C70
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!
Check the communication cable (k-line) between diagnostic outlet #7 and the driver information module (DIM) #B4 and other connected control
modules for open circuit, short-circuit to ground and short-circuit to voltage.
Caution! In case of malfunction on this communication cable, communication cannot be established on the high-speed network. First
when communication takes place on this cable, the high-speed cables between the diagnostic outlet and driver information module (DIM)
are connected to the high-speed network in the vehicle. This is controlled via a relay in the driver information module (DIM).
Check communication cables between diagnostic outlet #6/#14 and the driver information module (DIM) #A19/#A20 for open circuit,
short-circuit to ground and short-circuit to voltage according to references above.
Also check the communication cables for thehigh-speed networkbetween the driver information module (DIM) and the other connected control
modules according to troubleshooting above.
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 5.2
Check the communication cable between diagnostic outlet #3 and engine control module (ECM) for open circuit, short-circuit to ground and
short-circuit to voltage according to references above.
Check that the control module's voltage feed and ground connection are trouble-free.
Caution! Model year 99- and control modules on the CAN-network. If none of the above checks help, try reading out diagnostic trouble codes
in the driver information module (DIM). Done via VIDA vehicle communication. A prerequisite for being able to communicate with the control
