Troubleshooting Issues After Installation

Lytx event recorders have built-in diagnostic tools to help troubleshoot issues you may exper-
ience. If you're having issues with the SF-Series event recorder, initiate the device's
Diagnostic Mode. In this mode, the device's LED status lights will help identify the specific
component of the device that may be causing the issue.
This section provides instructions on how to initiate the Diagnostic Mode, definitions of each
of the device's LED status lights, and steps for troubleshooting.
To initiate the Diagnostic Mode, the device must be rebooted. After the reboot sequence is
finished, the device will enter the Diagnostic Mode.

Possible Causes and Solutions
The vehicle battery may be disconnected. Reconnect the
battery or check the battery cut-off switch.
Ensure the red wire on the Vehicle Interface Cable/Non-ECM,
Device Power Only Cable is connected to a constant power
source.
The fuse may be missing or open. Check the fuse panel loca-
tion for constant power. Ensure the proper value fuse is
installed and not open.
(For installations with a Vehicle Interface Cable) The connec-
tion between the Device Power Cable and the Vehicle Inter-
face Cable may not be fully secured. Check the connection.
Disconnect and reconnect the cables, ensuring the connection
"snaps".
Note: The Device Power Cable connector into the event
recorder has a locking tab. To disconnect, push in the locking
tab before pulling out. Failure to do so may cause damage to
the device.
The red wire on the Vehicle Interface Cable/Non-ECM, Device
Power Only Cable may be damaged. Check the entire length of
the wire for damage/cuts. Fix any issues.
There may be an issue with the brown wire connection. Check
the wire for damage. Gauge the wire with a voltmeter for
12V/24V with the ignition on. Check the vehicle fuse for that
circuit.
Contact Lytx Technical Support. The device must be returned.
