DTC P1E3C

-
Control Module Calculated Hybrid/EV Battery Performance

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.

The hybrid powertrain control module performs internal calculations multiple times and compares the results of these calculations to verify proper operation of the internal controller memory. The result of these calculations is a voltage value. This voltage value is an internal value and cannot be measured externally. This fault is handled inside the generator control module and no external circuits are involved.

Conditions for Running the DTC

* The 12 V battery voltage is greater than 9 V.

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

Conditions for Setting the DTC

If the results of these calculations differ by more than one volt.

Action Taken When the DTC Sets

* DTC P1E3C is a type A DTC.

* The high voltage contactor relay will be opened.

Conditions for Clearing the DTC

DTC P1E3C is a type A DTC.
