Why my Lytx Voice Recorder ER-SF1 fails to power up after installation?

  Steven ClineAug 15, 2025
  If your Lytx Voice Recorder ER-SF1 fails to power up post-installation, consider these potential causes: * The vehicle battery might be disconnected; reconnect it or check the battery cut-off switch. * Ensure the red wire on the vehicle interconnect cable is connected to a constant power source. * A fuse may be missing or open; verify the fuse panel location for constant power and ensure the correct fuse is installed and functional. * The connection between the standard power cable and the vehicle interconnect cable might not be fully secured; disconnect and reconnect, ensuring a secure "snap." * The red wire on the vehicle interconnect cable could be damaged; inspect the entire wire for damage and repair as necessary.

  If the Lytx Installation Tool isn't detecting engine RPM, here are a few things to check: * Make sure the vehicle is running. If it is, try turning the device off and on, either by disconnecting the power cable or by entering the device's Diagnostic Mode. * Ensure that the Yellow wire is on the CAN-HI (Y) side of the Coupler and the Green wire is on the CAN-LO (G) side, as the wires may be reversed over the CAN Coupler. * Check the CAN Coupler to make sure it is fully engaged. * The CAN Coupler may not have been placed on the CAN backbone, but on a stub. Try moving the Coupler to a different location.

  If your Lytx Voice Recorder ER-SF1 isn't booting correctly and disconnects from the Lytx Installation Tool, it could be due to: * Insufficient current on the constant power connection. Check the connection and ensure the source wire can supply 5 amps. * A loose or insufficient chassis ground. Inspect the ground connection to ensure it's tight and located free of paint or rust.

  If your ER-SF1 isn't exiting Hibernate mode when you activate the ignition, it might be due to an issue with the brown wire connection. Check the wire for any damage, and use a voltmeter to ensure it's receiving 12V/24V when the ignition is on. Also, inspect the vehicle's fuse for that circuit.

What does solid Yellow LED status light on Lytx Voice Recorder ER-SF1 mean?
- K
  Karen StoutSep 12, 2025
  If your ER-SF1 shows a solid Yellow LED, it indicates an issue with the cellular modem. For CDMA units, it means the modem hasn't been provisioned correctly. With GSM modems, the SIM card might not be seated properly. Try reseating the SIM card to see if the light changes to Green. If it remains Yellow, contact Lytx Technical Support.
