3.3 Connecting to Vehicle Power
The Data Cable, included with your MICROSCAN unit, plugs directly into the data link
connector (DLC) on OBD-II/EOBD vehicles.
z To connect to vehicle power:
1. Attach the 15-pin connector of the Data Cable to the MICROSCAN unit. Tighten the
captive screws to ensure a good connection.
2. Connect the 16-pin connector of the Data Cable to the DLC of the test vehicle.
3. Switch the vehicle ignition on.
4. The MICROSCAN unit automatically powers on and checks for diagnostic trouble codes
(DTCs) stored in the electronic control module (ECM) of the vehicle.
NOTE:
i This scan tool can communicate with many non-OBD-II/EOBD vehicles, however, a data
cable adapter and other optional equipment may be needed to connect to the vehicle and to
power the tool. Contact your sales representative for details.
3.3.1 Auxiliary Power Cables
The two auxiliary power cables are included with MICROSCAN are used for testing pre-1996
vehicles without battery power on the diagnostic connector. Optional data cable adapters,
which work with the auxiliary power cables, are also needed to test these earlier vehicles.
IMPORTANT:IMPORTANT:
The gray colored data cable adapters are designed exclusively for use with MICROSCAN.
Red or black Snap-on adapters for VERUS, MODIS, SOLUS PRO and other Snap-on scan
tools are not compatible with MICROSCAN.
z To use the auxiliary power cables on OBD-I vehicles:
1. Connect the required test adapter to the data cable.
2. Plug the small end of the Lighter Power Cable into the port on the test adapter.
