The engine torque can vary between -100 Nm and +400 Nm. Negative values indicate engine braking.

The TC/ABS control module sends information with a request for torque to the engine control module. This information is sent via the P-bus. The request can vary between +10 Nm and +400 Nm. 400 Nm will be requested when TC regulation is inactive. Information is used in the engine control module together with other information in order to supply the correct torque to the drive wheels. Also see the description of the engine control module.
