This parameter displays the learned minimum value of throttle position (TP) sensor 1 as recorded by the control module during the last learn procedure.
|
Throttle Position Sensor 1 or 2 Position
|
Ignition ON
|
%
|
This parameter displays the actual voltage on the TP sensor 2 signal circuit as measured by the control module.
|
Throttle Position Sensor 2 Learned Minimum
|
Ignition ON
|
0.5-0.9 V
|
This parameter displays the learned minimum value of TP sensor 2 as recorded by the control module during the last learn procedure.
|
Throttle Position Sensors 1 and 2
|
Ignition ON
|
Agree/Disagree
|
This parameter displays Disagree when the control module detects that TP sensor 1 voltage signal is not within the correct relationship to TP sensor 2. The scan tool displays Agree under the normal operating conditions.
|
Traction Control Status
|
Ignition ON
|
Active/Inactive
|
This parameter displays Active if the electronic brake and traction control module (EBTCM) is commanding traction control.
|
Torque Delivered Signal
|
Vehicle Moving
|
Nm/lb ft
|
This Parameter displays the engine torque based upon the airflow through the engine and the torque losses due to spark retard and fuel shutoff. Since this is a steady state engine torque, it does not include the inertial component of engine torque.
|
Torque Management Ignition Timing Retard
|
Engine Idling
|
Degrees
|
This Parameter displays the total spark retard (in terms of a crankshaft angle).
|
Torque Request Inhibit-Fuel
|
Engine Idling
|
Yes/No
|
This Parameter displays the existing condition in the ECM causing the transmission torque request to be limited.
|
Torque Request Inhibit-Ignition Timing
|
Engine Idling
|
Yes/No
|
This Parameter displays the existing condition in the ECM causing the transmission torque request to be limited.
|
Torque Request Inhibit-Ignition Timing Advance
|
Engine Idling
|
Yes/No
|
This Parameter displays the existing condition in the ECM causing the transmission torque request to be limited.
|
Torque Request Inhibit-Minimum Idle
|
Engine Idling
|
Yes/No
|
This Parameter displays the existing condition in the ECM causing the transmission torque request to be limited.
|
Torque Request Inhibit-Minimum Torque
|
Engine Idling
|
Yes/No
|
This Parameter displays the existing condition in the ECM causing the transmission torque request to be limited.
|
Torque Request Inhibit-TAC
|
Engine Idling
|
Yes/No
|
This Parameter displays the existing condition in the ECM causing the transmission torque request to be limited.
|
Torque Request Inhibit-TAC Limit
|
Engine Idling
|
Yes/No
|
This Parameter displays the existing condition in the ECM causing the transmission torque request to be limited.
|
VIN Programming Counter
|
Ignition ON
|
Quantity
|
This Parameter displays the number of times the VIN has been programmed. This counter can only be incremented.
|
Vehicle Speed Sensor
|
Vehicle Moving
|
Km/h
mph
|
This parameter displays the speed of the vehicle as calculated by the transmission control module (TCM) from information received from the vehicle speed sensor (VSS).
|
Warm Ups Since DTC Cleared
|
Ignition ON
|
Quantity
|
This parameter indicates the number of warm up cycles that have occurred Since DTCs were cleared. The scan tool will display a higher counts as more warm up cycles have occurred since the DTCs were cleared.
|
Warm Ups without Emission Malfunctions
|
Ignition ON
|
Quantity
|
This Parameter displays the number of OBD defined warm up cycles since the last emissions related (fault type A or B) fail report or MIL request. Emissions related DTCs are cleared from memory when this counter reaches 40.
|
Warm Ups without Non Emission Malfunctions
|
Ignition ON
|
Quantity
|
This Parameter displays the number of OBD defined warm up cycles since the last non emissions related (fault type C) fail report. Non emissions related DTCs are cleared from memory when this counter reaches 40.
|
Wide Open Throttle
|
Ignition ON
|
Yes/NO
|
This parameter displays the throttle status commanded by the control module. The scan tool will display YES if the vehicle throttle is commanded to 100 percent.
