What is Logging Malfunction (2)?
Logging Malfunction (2) is a system controller reset. This will typically occur when the ignition is detected but the unit is not receiving RPM data or if the GPS is showing movement but the JBUS cannot be detected. The system controller is reset in an attempt to correct this issue.
The most common cause of the Logging Malfunction (2) is keeping the ignition on in accessory mode (engine off). The unit, while detecting that the ignition is on but not receiving RPM data, will reset the controller every 10 minutes in an attempt to "correct" this issue.
