Learn Control (Enabled / Disabled)
Learn Control should be ENABLED when the Block Learn function is
active based on the ECM. When the ECM has determined that learn
control should be disabled as with an integrator at the calibration limit,
the screen should indicate DISABLED.
Learned Idle Pos (Steps)
Range: 0 to 255 Steps
The minimum number of counts needed by the idle air control motor to
reach a desired idle speed.
Left Integrator / Right Integrator
Range: 0 to 255
These parameters give integrator (short-term fuel trim) values
corresponding to either the left or right bank of cylinders in multi-bank
engine applications (see Integrator).
Left Block Learn / Right Block Learn
Range: 0 to 255
These parameters give block learn (long term fuel trim) values
corresponding to either the left or right bank of cylinders in multi-bank
engine applications (see Block Learn).
Left Oxy Sense / Right Oxy Sense (mV)
Range: 0 to 1200 mVolts
These parameters give the oxygen sensor values corresponding to either
the left or right bank of cylinders in multi-bank engine applications (see
Oxygen Sensor).
Left O2 Cross Counts / Right O2 Cross Counts Range: 0 to 255 Counts
These parameters give the oxygen sensor cross count values
corresponding to either the left or right bank of cylinders in multi-bank
engine applications (see O2 Cross Counts).
Loop Status (Open / Closed)
An open reading indicates an open loop in which the ECM controls the
air-fuel mixture from pre-stored table values. A closed reading indicates a
closed loop in which the ECM controls the air-fuel mixture from the
oxygen sensor and other sensors.
Low Oil Light (On / Off)
If the engine oil level reaches a minimum point of safety, the ECM will
indicate ON. Normal operation would be indicated by OFF.
Low Oil Pressure (Yes / No)
If the engine oil pressure reaches a minimum point of safety, the ECM will
indicate YES. Normal operation would be indicated by NO.
