Communication Fault

Communication has been interrupted for one of the following reasons

1. The ignition is switched off
2. VCT2000 disconnected from the data link connector (DLC)
3. VCT2000 disconnected from the VIDA cart
4. Communication problems in VIDA application or in car.
5. No voltage in the data link connector (DLC).

Check therefore

1. That the control module power supply and ground terminal are fault-free.
2. That the fuse for the data link connector (DLC) is intact.
3. that the ignition is on
4. 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»(ref-415474-S17299701082011081500000)
5. that VCT2000 is correctly connected to the VIDA cart and the data link connector (DLC)
6. that VCT2000 and the wiring is fault-free.

Other information

1. 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 following options.

1. Try again. Refer to «Calibration»(ref-415373-S13729855742011081500000) .
2. Fault-trace more comprehensively for the communication problem that has occurred. Refer to «Checking Communication Errors»(ref-415373-S18543539822011081500000) .
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. V70 (00-), V70 XC (01-)/XC70, S60, S80 and XC90. Refer to «Checking Communication Errors, Car Model V70 (00-), V70 XC (01-)/XC70, S60, S80 And XC90»(ref-415373-S23308911832011081500000) .

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.

1. Model year -2004 communicates with 250 kbit/s.
2. 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

1. Brake control module (BCM)/(ABS)
2. Engine control module (ECM)
3. Electronic Throttle Module (ETM)
4. Suspension Module (SUM)
5. Central electronic module (CEM)
6. Transmission control module (TCM)
7. Steering wheel angle sensor module (SAS)
8. Steering Wheel Module (SWM)
9. Electrical Power Steering Module (EPS)

If this happens, take the following action

1. Turn off the ignition and remove the ignition key. Insert the key again in position II.
2. If the above does not work, remove the battery cable and connect it again after a minute to reset the control modules.
3. Select the correct vehicle profile in VIDA and erase the diagnostic trouble codes. Check that the symptoms have disappeared.

Diagnostic outlet

1. Check the voltage feed to diagnostic outlet #16. The voltage shall match battery voltage.
2. 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!

Communication cables

1. 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 network. First when communication takes place on this cable, the low and high-speed cables between the diagnostic outlet and central electronic module (CEM) are connected to the rest of the network in the vehicle. This is controlled via a relay in the central electronic module (CEM). This relay is only found on vehicles of model year -2004.
2. For communication problems with control units on the high-speed network , check communication cables between diagnostic outlet #6/ #14 and central electronic module (CEM) #B7/ #B8 for open circuit, short-circuit to ground and short-circuit to voltage according to references above.
3. For communication problems with control units on the low-speed network , check communication cables between diagnostic outlet #3/#11 and central electronic module (CEM) #B19/#B20 for open circuit, short-circuit to ground and short-circuit to voltage according to references above.
4. Also check the communication cables for the low and high-speed net between the central electronic module (CEM) and the other connected control modules according to troubleshooting above.

Control modules

1. Check that the control module's voltage feed and ground connection are trouble-free.

VCT2000 and cable harness

1. Connect VCT2000 to the vehicle so that it is supplied with voltage. Test VCT2000 by selecting the system's self-test and VCT Test in the VIDA main menu. If any malfunction is found according to the test, first replace the cable harness then the VCT2000, if the test still indicates a malfunction.
2. If no malfunctions were found after troubleshooting according to above, try with a new cable harness and/or new VCT2000.

VIDA

1. If no malfunctions were found after troubleshooting according to above, try performing a complete system reset of VIDA.

HINT: After carrying out the repair, check that the fault has been remedied.

1. Ignition off
2. Reinstall the components, reconnect the connectors etc.
3. Ignition on. Read off the status of the diagnostic trouble code (DTC).

Is the status of the diagnostic trouble code (DTC) intermittent?

1. YES VERIFIED: Troubleshooting has been completed.
2. NO Refer to «Information»(ref-415373-S40654850862011081500000)

The fault should have been detected and remedied. As this is not the case fault-tracing has failed.

Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

The suspension module (SUM) has registered an internal fault. If the fault is intermittent, the fault has been registered on a previous occasion. Intermittent faults may be caused by interference at start up of the control module.

The fault can occur on different occasions. The software may need to be reloaded. To reload software, see Suspension Module (SUM), Replacing .

Select "Continue" when the fault has been remedied.
