12 volt supply used to monitor battery connection to the IPM. The battery connection to the IPM uses an internal switch to check integrity of the connection and that the Connector Positive Assurance (CPA) is engaged. If the CPA is not properly engaged, a voltage is sent to the FCM to be interpreted as an unseated connector which will set a Diagnostic Trouble Code (DTC).
