XC90 L5-2.5L Turbo VIN 59 B5254T2 (2004)
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 k-line
-
Check the communication cables between diagnostic outlet #7 and connected control modules for open circuit, short-circuit to ground and
short-circuit to voltage.
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 5.1 and diesel (not Lucas)
-
Check the communication cables between diagnostic outlet #11/#15 and engine control module (ECM) for open circuit, short-circuit to ground and
short-circuit to voltage according to references above.
Control modules
-
Check that the control module's voltage feed and ground connection are trouble-free.
VCT2000 and cable harness
-
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.
-
If no malfunctions were found after troubleshooting according to above, try with a new cable harness and/or new VCT2000.
VIDA
-
If no malfunctions were found after troubleshooting according to above, try performing a complete system reset of VIDA.
