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.
Limited Operating Strategy (LOS) Modes
The PCM may initiate one or more of the LOS modes for some hybrid electric system concerns. The objective of the LOS modes are to manage vehicle operation after one or more of the following systems are disabled due to a concern:
- engine
- transmission
- high voltage traction battery
- regenerative brake system
Some LOS modes limit the vehicle capability to a limp home condition. Other LOS modes fully disable the vehicle. The PCM initiates the appropriate LOS mode depending on the severity of the concern that was detected.
