Supplying Power to the Diagnostic Tool
Your diagnostic tool can receive power from any of the following sources:
Vehicle Power
The diagnostic tool is designed to be powered from the vehicle. All OBD-II/EOBD vehicles have vehicle battery power (B+) available on the data link connector (DLC). The diagnostic tool is powered through the Data Cable when connected to the vehicle DLC.
A green LED indicator on the DLC end of the data cable, illuminates when power is being supplied to the cable. If the LED fails to illuminate, check that the data cable is properly connected and then check the DLC power circuit.
An optional power cable is required when testing non-OBD-II/EOBD or models that do not have vehicle battery power (B+) available on the DLC. Contact your sales representative for availability.
Never connect the optional power cable to the power supply input jack on the diagnostic tool when the diagnostic tool is communicating with a vehicle.
AC Power Supply
The diagnostic tool can be powered from a standard AC outlet using the AC power supply. The AC power supply converts alternating current (AC) to direct current (DC) to power the diagnostic tool. The connector on the end of the output cable of the AC power supply connects to the AC power supply jack on top of the diagnostic tool. Use only the AC power supply provided.
Never connect the AC power supply to the diagnostic tool when the diagnostic tool is communicating with a vehicle.
