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 755 feet (about 230 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 programming device can receive power from both of the following

Sources:

Vehicle Power
AC/DC Power Supply

Vehicle Power

The J2534 programming device operates on 12-volt vehicle power, which it receives through the vehicle data connection port. The MS908P powers on whenever it is connected to an OBD II/EOBD compliant data link connector (DLC). For non OBD II/EOBD compliant vehicles, the device can be powered from a cigarette lighter or other suitable power port on the test vehicle using the auxiliary power cable.

AC/DC Power Supply

The J2534 programming device can be powered from a wall socket using the AC/DC power adapter.
