Scan Tool Data Definitions - Automatic
Transaxle - AF33-5
APP Angle: This parameter displays the position of the
accelerator pedal. A display of 0 percent indicates
that the accelerator pedal is fully released. A display
of 100 percent indicates that the accelerator is fully
depressed. The value indicated may not correspond
to the TP angle value.
Brake Switch: This parameter displays the state of the
brake switch circuit input. The scan tool will display
Applied when the brake pedal is depressed and
Released when the brake pedal is released.
Commanded Gear: This parameter displays the
current commanded state of the shift solenoid
valves. The scan tool displays 1, 2, 3, 4 or 5.
Cruise: This parameter displays the commanded state
of the cruise control system. The scan tool displays
ENABLED or DISABLED. When the display
indicates ENABLED, the PCM is allowing cruise
control operation. When the display indicates
DISABLED, the PCM has disabled cruise control
operation. When the cruise control display is
ENABLED, shift patterns will be altered for 2-3 and
3-4 upshifts or 4-3 and 3-2 downshifts.
ECT: This parameter displays the input signal from the
engine coolant temperature (ECT) sensor. ECT is
high at 151°C (304°F) when the signal voltage is low,
0 volt. ECT is low at −40°C (−40°F) when the signal
voltage is high, 5 volt.
Engine Run Time: This parameter displays a measure
in Hr: Min: Sec of the length of time the engine has
been operating. When the ignition is cycled to OFF,
the value is reset to zero.
Engine Speed: This parameter displays the rotational
speed of the engine expressed as revolutions per
minute.
Engine Torque: This parameter displays a calculated
value based on engine load, throttle position, mass
air flow, and other engine inputs. This parameter is
accurate to within 20 N⋅m (15 ft lb) of actual
measured engine torque.
Gear Ratio: This parameter displays the actual
transmission gear ratio. The scan tool displays the
gear ratio calculated from the automatic
transmission input shaft speed sensor (AT ISS) and
the automatic transmission output shaft speed
sensor (AT OSS) inputs.
Ignition Voltage: This parameter displays the system
voltage measured at the ignition feed.
Last 1-2 Shift Status: This parameter displays the shift
quality of the last 1-2 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Automatic Transmission:
Last 2-1 Shift Status: This parameter displays the shift
quality of the last 2-1 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Last 2-3 Shift Status: This parameter displays the shift
quality of the last 2-3 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Last 2-4 Shift Status: This parameter displays the shift
quality of the last 2-4 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Last 3-2 Shift Status: This parameter displays the shift
quality of the last 3-2 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Last 3-4 Shift Status: This parameter displays the shift
quality of the last 3-4 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Last 4-2 Shift Status: This parameter displays the shift
quality of the last 4-2 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Last 4-3 Shift Status: This parameter displays the shift
quality of the last 4-3 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Last 4-5 Shift Status: This parameter displays the shift
quality of the last 4-5 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
Last 5-4 Shift Status: This parameter displays the shift
quality of the last 5-4 gearshift. The scan tool
displays Good, Long, Short, Tie-Up, Flare, or
Inconclusive. Inconclusive is displayed if the
conditions for determining the last shift status were
not met.
