Checking communication problems
Checking communication errors
Selecting car model
Select car model to obtain relevant troubleshooting information.
Select one of the following model alternatives
1. S40 (04-) / V50.
2. V70 (00-), V70 XC (01-) / XC70, S60, S80 and XC90.
3. V70 (-00), V70 XC and S70 / C70.
4. S40 (-04)/ V40.
1 - car model S40 (04-) / V50
2 - car model V70 (00-), V70 XC (01-) / XC70, S60, S80 and XC90
3 - car model V70 (-00), V70 XC and S70 / C70
4 - Checking communication errors car model S40 (-04) / V40
------------------------
Checking communication errors, car model S40 (04-) / V50
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.
Diagnostic outlet
-
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!
Communication cables
-
For communication problems with control units onthe high-speed network, check communication cables between diagnostic outlet #6/ #14 and
central electronic module (CEM) #B11/ #B12 for open circuit, short-circuit to ground and short-circuit to voltage according to references above.
-
For communication problems with control units onthe low-speed network, check communication cables between diagnostic outlet #3/#11 and
central electronic module (CEM) #B16/#B15 for open circuit, short-circuit to ground and short-circuit to voltage according to references above.
-
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.
