DTC P1430 (40): Motor Drive Module (MDM) Short Circuit Sensor Problem: General Description

If the flag short circuit (FSC) signals from the motor power inverter (MPI) module do not vary from a low voltage level to a high voltage level within a set time after turning the ignition switch on, a malfunction is detected. The signals vary from a low voltage level to a high voltage level within a set time (t0) under normal conditions. If a problem occurs in the signal circuit, the signals stay at a low voltage level for a set time (t1) (t1>t0) after turning the ignition switch on, and the motor control module (MCM) detects a malfunction and stores a DTC.
