System diagram
Hint:
- The abs and traction actuator (skid control ecu) detects and stores steering sensor and yaw rate sensor dtcs and performs dtc communication by receiving information from the steering sensor and yaw rate sensor.
- The ecm uses the can communication system to perform dtc communication instead of the conventional communication line (sil).
