Torque control
The control module requests torque-limiting from the engine control module (ECM) in order to limit the torque immediately before shifting to improve shifting quality. The torque is limited by the ignition and fuel injection.
Measurement range: -512 - +512 Nm
Engine torque
The transmission control module (TCM) requests torque-limiting from the engine control module (ECM) in order to limit torque immediately before shifting. The signal is used to inform the ABS control module when the driver has requested torque reduction. This is so that the torque will return to the correct level after reduction.
Measurement range: -512 - +511 Nm
511 = No torque limiting request
Torque reduction when shifting
The transmission control module (TCM) requests torque-limiting from the engine control module (ECM) in order to limit torque immediately before shifting. Torque limiting can occur at three different levels: 25 %, 35 % or 45 %. Limitation lasts for less than 1 second.
0 = No torque limiting requested
25, 35, 45 % = Torque limiting requested
Torque limiting requested
The transmission control module (TCM) requests torque-limiting from the engine control module (ECM) in order to limit torque immediately before shifting. The signal is used to inform the ABS control module when the driver has requested torque reduction. This is so that the torque will return to the correct level after reduction.
Measurement range: -512 - +511 Nm
511 = No torque limiting request
