Engine torque can vary between -100 N.m and +400 N.m. Negative values indicate engine braking.

The TC/ABS control module sends information to Trionic with a request for torque. This information is sent via the P-bus. The request can vary between +10 N.m and +400 N.m. When TC modulation is not active, the request will be 400 N.m. Information is used in Trionic, together with other information, to supply the correct torque to the driving wheels.
