Software Download
The Software Download function of TIS2Web is used to update the Tech2 scan tool
software to the latest version. Like all computers, the Tech2 scan tool stores software that
determines how it runs and what it can do. This software allows the scan tool to perform
diagnostic routines on or for the following vehicle applications: Powertrain, Body, Chassis,
and Service Programming.
Scan tool software is regularly updated to reflect changes in vehicle engineering or
diagnostics. Scan tool software updates can include new vehicle and system coverage,
updates to original application releases, and fixes to known software concerns.
Tech2 PCMCIA Card
Notice:
The PCMCIA card is sensitive to magnetism and static electricity. Use care when
handling.
IMPORTANT:
The PCMCIA card is accessed through a door on top of the Tech2, and
should only be removed if instructed by the ACDelco Aftermarket Support Center. The card
is ejected by pushing the arrow button pointing to card to be removed. Cards are notched
to allow insertion only one way. When reinserting the card make sure that it fully seats into
the Tech2. The PCMCIA card fits into Slot 1, which is closest to the screen. The second
slot is identified as Slot 2.
The Tech2 software is stored on a Personal Computer Memory Card Industry Association
(PCMCIA) card.
All of the applications share a single database on the PCMCIA. See screen captures for
ejection of PCMCIA card, PCMCIA card keying, and PCMCIA card insertion.
The card can store at least two snapshots and one Capture Info data file. This allows
analysis of intermittent conditions on a vehicle being serviced.
A write-protect slide mechanism is on the top edge of the card
—usually under a white
plastic CPA-type device on new cards. If the write-protect slide mechanism is in the locked
position, you will not be able to store snapshots or captured information, and service
programming will not work. The correct position is at the middle of the card (unlocked).
J-45080 32-MB PCMCIA Card
Background:
When the Tech2 was introduced in 1996, it was equipped with a 10-MB (10-megabyte)
PCMCIA card, which had 10 times the capacity of the original mass storage cartridge of
the Tech 1. The 10-MB card was installed in Slot 1, closest to the screen, with Slot 2
reserved for future use.
Vehicle on-board computer capabilities multiply with each new model year, and the Tech2
has had to keep pace. The capacity of the 10-MB card reached its limits, and it was time to
expand again.
