PTO STATUS (OFF or ON)
Power Take Off Status allows module to keep track of Power at Take-Off.
REL FRP (0 – 5177.27 kPa) or (0 – 750. psi)
Relative Fuel Rail Pressure (Vacuum) is the fuel rail pressure at engine.
REL TPS (0 – 100%)
Relative Throttle Position is the normalized relative throttle position.
SECOND AIR (AIR_STAT: UPS, DNS or OFF)
Commanded Secondary Air Status is on newer vehicles and actuators to control pollution
control.
UPS - UP STREAM module is demanding that secondary air be added at exhaust
manifolds
DNS - DOWN STREAM module is demanding secondary air be added at catalytic
converter
OFF - Module is demanding no secondary air to be added.
ST FTRMxy (- 100 – 99.22%)
Short-term Fuel Trim Bank calculated value represents the short-term relation of fuel meter-
ing on a fuel-injected engine.
✓
Short-term Fuel Trim calculated 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 negative 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 throttle 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 tempera-
ture 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 driveability. 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 vehicle 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.
Therefore, the VPWR value may be significantly different than the battery.
