DTC P1D65
DTC P1D65: HV System Shutdown (Collision Detection Signal Detected)
General Description
The electric powertrain system contains a system that shuts down the high voltage line when the vehicle crashes. The SRS unit sends vehicle crash information to the battery condition monitor module via a dedicated signal line when the SRS unit detects that the vehicle has crashed. When the battery condition monitor module keeps receiving vehicle crash information from the SRS unit for a set time, the battery condition monitor module judges that the crash shut down condition has been met, and shuts down the high voltage contactor and the high voltage sub contactor.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, a Pending DTC, a Confirmed DTC, and the freeze data are stored in the battery condition monitor module memory. The MIL does not come on.
Conditions for clearing the DTC
The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command or the battery condition monitor module reset.
