(Default value) 1 - The desired intervention regarding ignition angle retardation and cylinder shut-off is executed; however, the requested target torque can not be adjusted precisely (torque steps) 2 - The torque reduction regarding the ignition angle retardation cannot be completely executed. A cylinder shut-off is not possible at this time. Therefore a remaining torque (as difference between TQI_ASR/GS_REQ and TQI_AV) is present and cannot be reduced. 3 - The desired torque intervention for TCS regarding the ignition angle and cylinder shut-off can no longer be executed. The torque intervention is terminated, the engine management system resets the requested engine torque to the TQI value using a ramp.
