Circuit/System Description

The hybrid/EV powertrain control module 2 monitors a control pilot signal from the drive motor battery charger cable. The hybrid/EV powertrain control module 2 utilizes this signal to manage the charging process between the drive motor battery charger cable and the hybrid/EV powertrain control module 2.

Under normal charging conditions the control pilot signal is generated by the drive motor battery charger cable. This diagnostic runs with the drive motor battery charger cable disconnected to verify the vehicle side circuit integrity. The diagnostic signal is generated internally by the hybrid/EV powertrain control module 2.
