Answer

These engine faults are generated by the device when it detects a problem communicating with the engine for various reasons. The root cause for the issue is likely due to the bad installation, faulty harness or device.

For basic troubleshooting, check the device installation and power cycle the device (unplug and plug back in). Make sure the device is secured with a zip tie and there is no loose harness connection.
