Communication
The J2534 ECU Programming Device supports Bluetooth and USB
communications. It can transmit vehicle data to the display tablet with or without a
physical connection. The working range of the transmitter through Bluetooth
communication is 210 feet (about 70 m). A signal lost due to moving out of range
automatically restores itself when the display tablet unit is brought closer to the VCI
unit.
Power Sources
The J2534 ECU Programming Device can receive power from both of the following
sources:
Vehicle Power
AC/DC Power Supply
Vehicle Power
The J2534 ECU Programming Device operates on 12-volt vehicle power, which it
receives through the vehicle data connection port. The device powers on whenever it is
connected to an OBDII/EOBD compliant Data Link Connector (DLC). For non
OBDII/EOBD compliant vehicles, the device can be powered from an auxiliary power
outlet adapter or other suitable power ports on the test vehicle using the auxiliary power
cable.
AC/DC Power Supply
The J2534 ECU Programming Device can be powered from a wall socket using the
AC/DC power adapter.
