Cylinder compression measurement deviation
Compares two compression measurement results and returns their relative difference; it does not determine the cause of the difference.
Battery voltage drop under load
Calculates the difference between open-circuit and loaded voltage without automatically assessing battery condition.
Alternator charging voltage deviation
Compares measured charging voltage with a provided reference voltage without assessing the cause of the deviation.
Ideal runtime under parasitic drain
Estimates ideal runtime from battery capacity and drain current without accounting for operating conditions.
Combined STFT and LTFT fuel trim
Adds short-term and long-term fuel trim; the result is not interpreted as a specific fault.
Wheel speed deviation
Compares measured speed with a reference speed and returns the absolute percentage deviation.
Sensor signal as percent of range
Converts a signal relative to the provided minimum and maximum; out-of-range values are allowed for erroneous-signal analysis.
Coolant warmup rate
Calculates average coolant temperature change rate in K/min from two temperatures and elapsed time.
