J2534 Reprogramming Capability
The J2534 ECU Programming Device is a SAE J2534-1 & -2 compliant
PassThru reprogramming 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.
Communication
The J2534 ECU programming device supports Bluetooth, Ethernet and USB
communication. It can transmit vehicle data to the MaxiSys display tablet with
or without a physical connection. The working range of the transmitter through
Bluetooth communication is 980 feet (about 300 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.
