Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Drive Motor Control Module
Location
The drive motor control module is a flash-programmable micro-processor. The drive motor control module is non serviceable and is part of the generator control module.
Operating Functions
The drive motor control module's main function is to monitor the drive motor input/output circuits and to control the insulated gate bipolar transistors that control the drive motor by inverting the high voltage DC electrical energy to 3 phase AC electrical energy and vice versa.
Communication and Hosted Diagnostics
The hybrid powertrain control module communicates with the drive motor control module using an internal serial data circuit. The drive motor control module does not store its own diagnostic trouble code (DTC) information. The hybrid powertrain control module will store the drive motor control module associated DTC information for retrieval by a scan tool. The scan tool can communicate directly with the drive motor control module in order to retrieve data parameters only.
Circuit Inputs
In addition to data parameters, the drive motor control module monitors the drive motor for:
- Voltage
- Current
- Speed and direction
- Temperature
Additionally, the drive motor control module monitors the insulated gate bipolar transistor components for temperature and proper operation. Some of the drive motor control modules operation data is shared with the hybrid powertrain control module.
Circuit Outputs
The drive motor control module controls the insulated gate bipolar transistor driver board which is located in the drive motor control module, that in-turn controls the drive motor. The drive motor is controlled by the 3-phase alternating current (AC). Three cables connect the drive motor to the drive motor control module which is part of the generator control module.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
