DTC P1585 (30): Motor Current Sensor Circuit Malfunction




General Description
The motor control module (MCM) controls the IMA motor output based on the signal of the motor current sensors. When the motor current sensors malfunction, the output torque of the IMA motor may not be able to be controlled normally. The MCM monitors the sum of the three-phase current (IUPH, IVPH, and IWPH) at regular intervals, and when it exceeds a certain value, it is added to the counter.

When the count is within a specified value for a set cycle continuously, it is subtracted and when the count value exceeds a specified cycle value, a malfunction of the motor current sensor is detected and a DTC is stored.

Enable Conditions

Malfunction Threshold
The sum of the three-phase current (IUPH, IVPH, and IWPH) is more than 60 A or less than -60 A and either condition occurs more than 50 times.
(When the count value is within a specified value ten times continuously, it is subtracted from the count.)

Diagnosis Details

Conditions for illuminating the MIL
When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the PCM and MCM memory.

Conditions for clearing the MI
The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by disconnecting the battery.
