en 18 | VDI III | Troubleshooting
6.5 VDI III switches off immedia-
tely when disconnected from
the vehicle during a diagnostic
session
If VDI III does not remain on during cranking
or after the DLC connection is interrupted,
there may be a problem charging the internal
capacitor.
VDI III should remain on if power is lost during
engine cranking or after it has been disconnec-
ted from the electrical system (the vehicle's
DLC) during a diagnostic session. The VDI III
speaker will beep to notify the user that power
has been lost unexpectedly during the diagno-
stic session.
Recommendations
1. Check the 12 V voltage supply of the vehicle
DLC.
2. Ensure that VDI III has been connected to
the vehicle's DLC for at least 90 seconds to
charge the internal capacitor.

flashes
If the internal temperature of VDI III has excee-
ded the maximum limit, VDI III will automati-
cally turn off the wireless adapter. This will be
visible to the user by the checkmark LED flas-
hing. When the internal temperature of VDI III
drops to an acceptable value, the wireless
adapter will be re-enabled for wireless commu-
nication.
Recommendations

Move VDI III to a cooler location near the
vehicle.

6.7 Suspected defective diagnostic
connection cable
If a defective diagnostic connection cable is
suspected, perform the VCI Manager cable test.
The "VCI Manager" software supports a cable
test by means of the self-test adapter. The cab-
le test indicates whether or not the diagnostic
connection cable is defective. The self-test
adapter used for the test is not intended to be
used for vehicle communication. Perform the
following steps.
1. Connect the diagnostic connection cable to
VDI III.
2. Connect the self-test adapter to the vehicle
end of the diagnostic connection cable.
3. Power the self-test adapter either by the
vehicle connection or a 12 V power supply
unit.
4. Start VCI Manager, and connect VDI III.
5. In VCI Manager, select "Help."
6. Click <Cable test> to start the test
"
The "VCI Manager" software will run a series
of tests of the diagnostic connection cable.
The results will be indicated as PASS or FAIL.
