DTC P1D92: General Description
The power control unit (PCU) controls the PCU electric coolant pump according to the rotational speed of the PCU electric coolant pump calculated from the frequency (duty fixed to 50 %) detected from the NEWP terminal. If either of the following conditions occurs, the motor control module in the PCU detects a malfunction and stores a DTC.
Symptom 1
If the NEWP output equivalent to "85 % duty" output when the EWP detects an open / short to power of the EWP wire or a trouble with EWP input duty waveform (continuous Hi signal) is out of a specified value for a specified time, the motor control module in the PCU detects a malfunction and stores a DTC.
Symptom 2
If the NEWP output which is output when a short circuit of the EWP wire or a trouble with EWP input duty waveform (abnormal interval) is out of a specified value for a specified time, the motor control module in the PCU detects a malfunction and stores a DTC.
