IMPORTANT
Do not disconnect the programming device while the vehicle LED status light is on! If the
flash programming procedure is interrupted while the vehicle's ECU is blank or only
partially programmed, the module may be unrecoverable.
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.
2.2.1.2 Communication Capability
The MaxiFlash VCI supports Bluetooth (BT), Wi-Fi, and USB communications. 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). The working range of 5G Wi-Fi is up to 164 feet (50 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 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.
2.2.2.2 AC/DC Power Supply
The VCI can be powered from a wall socket using the AC/DC power adapter.
