2.2.1.1 Programming Capability
The MaxiFlash VCI is a D-PDU, SAE J2534 & RP1210 compliant PassThru programming
interface device. Using the updated OEM software, it is capable of replacing the existing
software/firmware in the Electronic Control Units (ECU), programming new ECUs, and
fixing software-controlled drivability issues and emission issues.
IMPORTANT
DO NOT disconnect the MaxiFlash VCI while the vehicle LED is on. If the reprogramming
procedure is interrupted while the vehicle's ECU is blank or only partially programmed,
the module may be unrecoverable.
2.2.1.2 Communication Capability
The MaxiFlash VCI supports Bluetooth and USB communication methods. It can transmit
vehicle data to the tablet with or without a cable connection. In open areas, the working
range of the transmitter through Bluetooth communication is up to 328 feet (about 100
m). If the signal is lost due to being taken out of range, communication will be restored
once the tablet is within range.
2.2.2 Power Sources
The VCI can receive power from the following sources:
 Vehicle power

AC/DC power supply
2.2.2.1 Vehicle Power
The MaxiFlash VCI operates on 12/24 volt vehicle power, which receives power via 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 port on the test vehicle using the auxiliary power cable.
