DTC Descriptor
DTC P1E0A
- Drive Motor Control Module Torque Calculation Performance

Circuit/System Description

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

The motor control module performs redundant calculations of desired and achieved torque values. These values are continuously compared and should always be the same.

Conditions for Running the DTC

Ignition voltage is 10-18V.

Conditions for Setting the DTC

The difference between the redundant torque calculation and the primary calculation is greater than 38 Nm(28 lb ft).

Action Taken When the DTC Sets

* DTC P1E0A is a Type A DTC.
* The hybrid powertrain control module opens the high voltage contactor relay.

Conditions for Clearing the DTC

DTC P1E0A is a Type A DTC.
