power by using the battery disconnect switches.

Comm controller.
3. Remove the OrbComm controller.

Installation
1. Install the OrbComm controller. Connect the
wire harnesses to the controller.
2. Turn the key switch ON, but do not start engine.
Wait three minutes and watch for any error
messages on the VHMS controller LED lights
that might indicate a problem with the Orb-
Comm controller or communications to the con-
troller.
3. If there are no error messages, turn the key
switch OFF. If there are error messages, refer
to the VHMS Troubleshooting and Checkout
Procedures elsewhere in this section.
4. Fill out the "VHMS Initialization" form and send
it to Komatsu as instructed on the form. Failure
to submit the form to Komatsu will prevent
machine data from being sent to the Komatsu
computer center.
NOTE: The new controller should come with a
special Orbcomm Terminal Activation form that
includes space to list the failed controller serial
number and new controller serial number. Komatsu
must have this information to maintain accurate data.
5. It may take up to two weeks for Komatsu to acti-
vate the new OrbComm controller. During this
time, a manual download of data must be taken
one time each week using a laptop PC. This
data must then be sent to WebCARE using the
FTP feature in VHMS Technical Analysis Tool
Box program. Keep downloading data and
sending it to WebCARE one time each week
until the new OrbComm controller has been
activated.
Komatsu will notify the person who performed
the controller replacement by e-mail when the
new controller has been activated and no more
manual downloads will have to be performed.
