Technical Information Bulletin*:
Lift Gates and Unit Interference
It has been found that the use of lift gates that plug directly into the vehicle’s OBDII port may
interfere with Networkfleet’s Light Duty (L3500) device.
Lift gates require access to vehicle information like speed to operate. If the speed is greater than 0,
the lift gate will not move up or down as to prevent injury or unwanted movement in the gate when
the vehicle is in motion. Some, not all, lift gates plug into the OBDII port to get speed.
When a Networkfleet device is plugged into the OBDII port along with a lift gate, the lift gate’s speed
requests may not be answered by the vehicle’s computer because the Networkfleet device is
already communicating with it. This could cause the lift gate to stop working. Other times, the lift
gate may work and the Networkfleet device backs off for 5 minutes. This “backing off” may result in
loss of data or inaccuracies, such as missed trips or unrecorded key ons by our device.
Neither device (the lift gate or Networkfleet unit) that is plugged to the OBDII port can operate to
their full capacity because they are both interfering with each other. It is recommended that
customers wishing to operate a lift gate that plugs into the OBDII port should install a Networkfleet
Universal unit or 4200 to avoid interference in service and data recording.
Lift gates that do not operate via the OBDII port will not interfere with Light Duty devices.
