CDS G3—PCM 112 Freeze Frame Data
Shows how much of the total possible engine
power is being produced as a percentage. On a
normally aspirated engine, the engine load and
manifold pressure data follow each other in a
parallel fashion.
Battery voltage at the time the fault occurred.
Barometric pressure reading during the key cycle
that the fault occurred in.
Temperature of the air entering the intake plenum
at the time the fault occurred.
The total spark advance in degrees added to the
base spark advance table at the time the fault was
set in Freeze Frame.
Available engine output power as a percentage at
the time the fault was set in freeze frame.
Information that the PCM has received from the
command control module (CCM) (on DTS
engines), or the throttle demand sensor (on
mechanical engines). Measurement of the amount
of power requested by the operator or control
software.
Throttle position sensor measured in percentage
of the amount the throttle blade was open at the
time the fault was set in freeze frame.
Oil pressure measured in PSI at the time the fault
was set in freeze frame.
Sea pump pressure measured in PSI at the time
the fault was set in freeze frame.
The engine oil temperature measured in
Fahrenheit at the time the fault was set in freeze
frame.
The coolant temperature measured in Fahrenheit
at the time the fault was set in freeze frame.
The reported gear position at the time of the fault.
Measured in AD counts, this is the position of the
outboard between 0 (0%) and 1024 (100%) at the
time of the fault.
The manifold absolute pressure measured in kPa.
The angle refers to the angle of the crankshaft
where the vacuum is optimally measured. This is
the parameter at the time the fault was set in
freeze frame.
The state of fuel system monitoring.
Measured in AD counts, this is the engine oil level
between 0 (0%) and 1024 (100%) at the time of
the fault. (Not all engines are equipped with an oil
level sensor.)
