1. A method of detecting for primary circuit loss of an electronic stability control system for a vehicle comprising:

  • checking that a lateral acceleration sensor is installed and working properly;

    comparing an absolute value of the lateral acceleration sensor with a first pre-defined threshold;

    checking that a yaw sensor is installed and working properly;

    comparing an absolute value of the yaw sensor with a second pre-defined threshold;

    checking that a steering wheel angle sensor is installed and working properly;

    comparing an absolute value of the steering wheel angle sensor with a third pre-defined threshold;

    determining that primary circuit loss detection is not required when any of the three sensors are equal to and above the respective pre-defined threshold; and

    determining that primary circuit loss detection is required when all of the three sensors are below the respective pre-defined threshold.
