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 starter/generator control module (SGCM) phase U/V/W current sensors are used for motor control and power inverter module (PIM) current sensor rationality check. The SGCM monitors the current sensor for the following:
- To detect a failure of the U/V/W-phase current sensor circuit below valid range
- To detect a failure of the U/V/W-phase current sensor circuit above valid range
If one of the above conditions is detected, the SGCM will set the appropriate DTC.
