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
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
Check the communication cable (k-line) between diagnostic outlet #7 and the driver information module (DIM) #B4 and other connected control
Caution! In case of malfunction on this communication cable, communication cannot be established on the high-speed network. First
Check communication cables between diagnostic outlet #6/#14 and the driver information module (DIM) #A19/#A20 for open circuit,
Also check the communication cables for thehigh-speed networkbetween the driver information module (DIM) and the other connected control
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
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
Check that the control module's voltage feed and ground connection are trouble-free.
