6.5 MTS 6531 turns off
immediately when disconnec-
ted from the vehicle during a
diagnostic session
If MTS 6531 does not remain on during
cranking or DLC disconnect, there may be a
problem charging the internal capacitor.
The MTS 6531 should remain powe-
red up if power is lost during engine cranking
or after it is disconnected from power (ve-
hicle DLC) during a diagnostic session. The
MTS 6531 speaker will beep to notify
the user that power has been lost unexpectedly
during the diagnostic session.
Recommendations
1. Check for 12 V power supply at the vehicle
DLC.
2. Ensure that the MTS 6531 has been
connected to the vehicle DLC for at least 90
seconds to charge the internal capacitor.
6.6 "Checkmark" LED flashing on
the MTS 6531
If the internal temperature of MTS 6531
has exceeded the maximum limit,
MTS 6531 will automatically turn off the
wireless adapter. This will be visible to the user
by the Checkmark LED flashing. When the inter-
nal temperature of MTS 6531 lowers to
an acceptable value, the wireless adapter will be
re-enabled for wireless communication.
Recommendations
¶
Move MTS 6531 to a cooler location
near the vehicle.

6.7 Suspected defective diagnostic
connection cable
If you suspect a defective diagnostic connection
cable, you should perform the cable test from
the VCI Manager. The "VCI Manager" software
supports a cable test with the use of the self-
test adapter. The cable test will suggest whether
or not the diagnostic connection cable is defec-
tive. The self-test adapter used for the test is not
intended to be used for vehicle communication.
The following steps can be used to perform the
cable test.
1. Connect the diagnostic connection cable to
the MTS 6531.
2. Connect the self-test adapter to the vehicle
end of the diagnostic connection cable.
3. Power the self-test adapter either via a vehic-
le connection or a 12-V power adapter.
4. Start VCI Manager and connect the
MTS 6531.
5. In VCI Manager, choose "Help".
6. Enter the security settings for the network
and select <Weiter> (Next).
"
The "VCI Manager" software will run a series
of tests on the diagnostic connection cable.
The results will be displayed as PASS or FAIL.
