DTC P1585 (30): Motor Current Signal Circuit Problem: General Description
If the output voltage is drifting or freezing due to a faulty phase current sensor, the motor output torque may not be properly controlled. If the three phase current sensors (Iu, Iv, Iw) work normally, the summation value is always 0 A. However, if one of the three sensors is drifting or freezing, the summation is not 0 A. By using a built-in circuit which calculates the sum of the three phase current sensor's amperage in the MCM (motor control module), the output from the counting circuit can be monitored. If the output is beyond a set value, a malfunction is detected and a DTC is stored.
