Enfo IV (109050) 090303 – 5 – Class 1
Engine RPM Display
The Engine RPM data is received from the engine ECU via CAN (PGN 61444,
EEC1).
Engine Oil Pressure Display
The Engine Oil Pressure data is received from the engine ECU via CAN (PGN
65263, EFLP1).
The ENFO IV will activate the alarm if the pressure drops to 10 PSI or lower.
When the pressure is low the display will alternately show the current pressure
and “LO”.
Engine Water Temperature Display
The Engine Water Temperature data is received from the engine ECU via CAN
(PGN 65262, ET1).
The ENFO IV will activate the alarm if the temperature reaches 250 degrees F or
higher.
When the Temperature is high the display will alternately show the current
temperature and “HI”.
Vehicle Voltage Display
The Voltage is derived from the main input Power and Ground pins and is
independent of CAN messages. Voltage is displayed with 0.1V resolution.
The ENFO IV will activate the alarm if the voltage falls to 11.9V and below (12V
ignition), or 23.8V and below (24V ignition). The voltage level must stay at the
low voltage range for a minimum of 2 seconds to activate the alarm.
When the voltage is low the display will alternately show the current voltage and
“LO”.
