S60 L5-2.4L VIN 64 B5244S6 (2003)
Continue - Fault Found
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:
Brake control module (BCM)/(ABS)
Engine control module (ECM)
Electronic Throttle Module (ETM)
Suspension Module (SUM)
Central electronic module (CEM)
Transmission control module (TCM)
Steering wheel angle sensor module (SAS)
Steering Wheel Module (SWM)
Electrical Power Steering Module (EPS)
If this happens, take the following action:
Turn off the ignition and remove the ignition key. Insert the key again in position II.
If the above does not work, remove the battery cable and connect it again after a minute to reset the control modules.
Select the correct vehicle profile in VIDA and erase the diagnostic trouble codes. Check that the symptoms have disappeared.
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 central electronic module (CEM) #D6 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 either the low or high-speed
