DTC Descriptor

DTC P0AEE

-
Drive Motor Inverter Temperature Sensor Performance

DTC P0AEF

-
Drive Motor Inverter Temperature Sensor Circuit Low Voltage

DTC P0AF0

-
Drive Motor Inverter Temperature Sensor Circuit High Voltage

Circuit/System Description

The generator control module also called the starter generator control module is comprised of the following three control modules; the hybrid powertrain control module, 14 volt power module and the drive motor control module. These three control modules are non serviceable and are part of the generator control module.

This is an internal fault detection of the generator control module. This fault is handled inside the generator control module and no external circuits are involved.

Conditions for Running the DTC

* DTCs P1A90, P1A91, P1A92, P1A71, P1A72, P1A73, P0A2B, P0A2C, P0A2D, P0A2F, P0AEE, P0AEF, P0AF0, P0C11 and P262B are not set.

* Ignition voltage is between 9-16V.

* The drive motor control module and the hybrid powertrain control module are awake.

P0AEE

The engine OFF time is greater than 8 hours.

Conditions for Setting the DTC

P0AEE

The temperature average of the drive motor temperature sensor and 14V power module temperature sensors 1 and 2 are 20°C (36°F) different from the Phase U DC/AC Inverter Temperature value.

P0AEF

The inverter phase temperature sensor 1 is greater than 150°C (302°F) for 3 seconds.

P0AF0

The inverter phase temperature sensor 1 is less than -70°C (-94°F) for 3 seconds.

Action Taken When the DTC Sets

* DTCs P0AEE, P0AEF, and P0AF0 are Type B DTCs.

* The power inverter module limits the maximum torque of the starter generator to 10.8 Nm (95.6 lb in).

* Autostop will be disabled.

Conditions for Clearing the DTC

DTCs P0AEE, P0AEF, and P0AF0 are Type B DTCs.

Circuit/System Verification

1. Allow the vehicle to cool to ambient temperature by leaving the ignition OFF for at least 8 hours.

2. Ignition ON, if the DTC is set, program the K59 starter generator control module. If the DTC resets, replace the K59 starter generator control module.

Repair Instructions

Perform the Diagnostic Repair Verification Verification Tests after completing the repair.
