SCAN TOOL DATA DEFINITIONS
Cold Shift Pattern:
Displays Enabled or Disabled.
This parameter indicates whether the transmission is
operating under a cold shift strategy.
Current Gear:
Displays 1, 2, 3, 4, or 5. This parameter
indicates the current commanded state of the shift
solenoids.
Driver Demanded Engine Torque:
Displays a range
of 0-9,999 lb ft. This parameter indicates the amount
of torque that is requested by throttle angle and driving
conditions.
ECT (Engine Coolant Temperature):
Displays a range
of -40°C to +151°C (-40°F to +304°F). This parameter
is the input signal of the engine coolant temperature
(ECT) sensor. When the ECT is high (151°C), the signal
voltage is low (0 V). When the ECT is low -40°C (-40°F),
the signal voltage is high (5 V).
Engine Run Time:
Displays a range of 0:00:00-
