A
manding that secondary air
be added at exhaust mani-
folds
DNS - DOWN STREAM module is
demanding secondary air be
added at catalytic converter
OFF - Module is demanding no sec-
ondary air to be added.
ST FTRMxy (- 100 – 99.22%)
Short-term Fuel Trim Bank calculated
value represents the short-term relation of
fuel metering on a fuel-injected engine.
✓
Short-term Fuel Trim calcu-
lated value that has a positive
percentage is a rich fuel trim
and if a negative percentage
is present the fuel trim is lean.
ST FLTRMx (- 100 – 99.2%)
Short-term Fuel Trim value represents the
short-term relation of fuel metering on a
fuel-injected engine.
✓
Short-term Fuel Trim value
with a positive percentage is
a rich fuel trim and if a nega-
tive percentage is present the
fuel trim is lean.
THR POS (0 – 100%)
Absolute Throttle Position is the position
the throttle is located. The more the throt-
tle is closed the less percent shown.
THROT CMD (0 – 100%)
Commanded Throttle Actuator Control is
the position of the throttle. If throttle is
closed the percent will be 0 and if wide
open 100%.
TRIPS SNC CLR (0 – 255)
Number of warm-ups since diagnostic
trouble codes cleared
. Warm-up is when
temperature of coolant rises to at least
22ºC (40ºF) from engine starting and
reaching a minimum temperature of 70ºC
(160ºF). In a diesel engine, the minimum
temperature is 60ºC (140ºF.)
✓
If there is more than 255 that
the engine warms up the
TRIPS SNC CLR will remain
at 255.
TROUB CODE (0000 – FFFF)
Trouble Code Parameter will give the
diagnostic trouble code that caused a
freeze frame capture. This information is
helpful in diagnosing the cause of a drive-
ability. If no freeze frame data has been
captured, this PID will be zero.
VEH SPEED (0 – 255 K/h) or (0 – 158
mph)
Vehicle Speed shows the speed the vehi-
cle is going.
VPWR (0 - 65.535V)
Control Module Voltage is the power input
to the control module.
✓
Vehicles using a 42V battery
may utilize multiple voltages
of different systems. There-
fore, the VPWR value may be
significantly different than the
battery.
