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.
Circuit/System Description
The power inverter module (PIM) temperature 1 sensor is used for overheat protection. The thermistor is located on the control board, near the phase W power MOSFET. The starter/generator control module (SGCM) monitors the inverter temperature sensor to detect the failure of the inverter temperature sensor circuit using rationality of other temperature sensors to determine if it is out of range.
