8. Finishing Up
After using the VCI, a few simple steps help you leave
the vehicle electronic system(s) in the proper state and
ensure that you get the most use out of your diagnostic
tools:
1.
Before turning the VCI off, exit any running PC com-
puter applications.
2.
Turn the VCI off by removing power. The Power LED
turns off.
3.
Disconnect the VCI's DLC cable from the vehicle.
4.
Disconnect the USB cable from the PC and the VCI.
5.
Store the VCI, cables, and other parts in a secure, dry
location.
9. Troubleshooting
This section is intended to help you get back on track if
the VCI appears to be operating abnormally. In addition,
the most likely cause for the condition is given as well as
other possible causes and recommendations on how to
isolate or eliminate the problem.
9.1
VCI Does Not Pass Power On Self-Test
(POST)
Most Likely Cause:
R
Internal problem in the VCI.
Recommendations:
¶
Connect the VCI to a PC using USB and perform the
recovery procedure.
9.2
VCI Error LED Lights After Power On
Most Likely Cause:
R
A problem has been detected during power on.
Recommendations:
¶
Power down the VCI and verify that it has the same
problem when you power up again.
¶
Connect the VCI to a PC using USB and perform the
recovery procedure.
9.3
VCI Fails to Power Up
The VCI should power up as soon as external power is
applied. If the VCI does not turn on, first check the cable
connections. Try supplying power to the VCI from two
different power sources— the vehicle DLC connector and
the USB connector.
Recommendations:
¶
Check that the cables are securely attached to the
VCI and the connector pins are clean.
¶
If connecting to the vehicle DLC connector, try pow-
ering from the USB connector.
¶
If powering from USB, try powering from the vehicle
DLC connector.
9.4
Vehicle LED is Blinking Red
If the VCI does not detect 12 V/24 V on Pin 16 of the DLC
cable, the VCI will inform the user by automatically turn-
ing on and blinking the Vehicle LED red. This condition
might be seen if the VCI is only powered by a 5 V USB
connection. When the VCI detects 12 V on Pin 16, the
Vehicle LED will stop blinking red.
Recommendations:
¶
Ensure 12 V is applied to Pin 16 of the DLC cable.
9.5
Suspected Defective Data Link Con-
nector (DLC) Cable
If you suspect a defective DLC Cable, you should per-
form a reference test with a sceond Data Link Connector
Cable.
Recommendations:
¶
Connect to the vehicle using another Data Link Con-
nector Cable. If Connection is successful exchange
the defect Data Link Connector Cable.
¶
Connect to a different vehicle, to make sure that the
vehicle connector does not cause any problems.
9.6
Wireless Communication with Network
Unsuccessful using WLAN dongle
The WLAN dongle is not intended to be used for PC wire-
less communication to a network. The WLAN dongle is
only intended to be used with the VCI for Point-to-Point
communication or Infrastructure wireless communica-
tion.
Recommendations:
¶
Make sure you do not have two wireless dongles
connected to the PC.
¶
Make sure you are not trying to connect the PC to
your dealership network using the WLAN dongle.
