Introduction
Power Supply
2.5.1 Vehicle Power
Vehicle power is required for the scan tool to properly communicate with the vehicle during
testing. The 93L Data Cable (EAC0093L01A) provides 12V power to the unit through the
vehicle data link connector (DLC). The scan tool turns on automatically whenever it is
connected to a DLC that provides power.
Certain vehicles do not provide vehicle power on the DLC. For these applications, a separate
cable adapter and power cable are needed to power the unit. Optional data cable adapters are
available for a number of vehicle manufacturers. Contact your sales representative for
availability.
The power cable connects to a port on the cable adapter.
IMPORTANT:
IMPORTANT:
Never connect the optional power cable or the AC/DC power supply to the DC power supply
input on top of the unit when the scan tool is communicating with the vehicle.
For related information, see “Connecting to Vehicle Power” on page 12.
2.5.2 Battery Power
This scan tool can receive power from six internal type AA batteries. Alkaline or rechargeable
nickel-metal hydride (NiMH) batteries must be used, Standard (lead/zinc) batteries do not
provide sufficient power and have a tendency to leak, which can damage the scan tool.
Battery power
should not
be the primary source of power. Vehicle power should be the source
of power during testing. Use battery power to review saved files and for identifying a test
vehicle without connecting to the DLC.

2.5.3 AC/DC Power Supply
The scan tool can be powered from a wall socket using the AC/DC power supply (Figure 2-5).
