X ActiveFaultMarqueeDisp –
(None) or fault
data
– Any active faults are displayed here.
X ActualGear Gear position actual
Neutral/forward/
reverse
–
The actual gear position based on the shift position sensor on
the engine.
X AEV_DutyCycle
Commanded position of
Active Exhaust system
90 or 10 Percent
Active Exhaust (Advanced Sound Control) feature; 90%
indicates stealth mode—low noise, 10% indicates sport mode—
higher noise.
X AG_Coolant_Volts
Analog gauge coolant
temperature output
Variable Volts
Sends a voltage relative to coolant temperature to an analog
gauge, if a gauge is present.
X AG_OilPress_Volts
Analog gauge oil pressure
output
Variable Volts
Sends a voltage relative to oil pressure to an analog gauge, if a
gauge is present.
X AG_Trim_Volts
Analog gauge trim position
output
Variable Volts
Sends a voltage relative to trim position to an analog gauge, if a
gauge is present.
X AirMarDepth Sea depth Variable m
Displays the depth of the water you are operating in (in meters),
if connected to an optional depth sensor.
X AirMarSeaTemp Sea temperature Variable ºC (ºF)*
The temperature of the water you are operating in, if the optional
lake and sea temperature sensor is being used. If a lake and sea
temperature sensor is not being used, the field will show a
default value of –50 ºC or –58 °F.
X Arb_TPS Throttle position 0–100 Percent The percent the throttle blade is open from the closed position.
X BARO Barometric pressure Variable
kPa (psi, in.
Hg)*
The barometric pressure reading when the key is turned on.
X BattVolt Battery voltage 12.0–14.5 V Volts
The DC voltage as measured by the PCM on the input side of
the system. Typical values range from 12.0–14.5 V.
X CTRL_Gear Gear position target
Forward/reverse/
neutral
– The gear position commanded by the remote control.
X Demand
Demand request by control
software
0–100 Percent
After demand is measured at the ERC, it may be adjusted by the
control software to account for functions such as Autosync,
Dock Mode, Cruise, Smart Tow, or Troll.
X DemandLinear
Demand request by
operator
0–100 Percent
A measurement of the throttle demand requested at the ERC or
throttle demand sensor.
X
DemandLinear_with_
Guardian
Demand request by
Guardian
0–100 Percent
After registering the demand from the ERC (DemandLinear), and
accounting for additional functions (Demand), any further
restrictions, such as Guardian, or Adaptive Speed Control, are
factored into this number.
X DemandSensor1
Mechanical demand
sensor A
0–100 Percent
This is a dual Hall‑effect sensor used only on mechanical
engines. It is mounted on the throttle and shift bracket. The
magnet is mounted on the throttle lever.
