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.
Operator Commanded Regeneration
For vehicles equipped with operator commanded regeneration, the vehicle must be at normal operating temperature, the PCM must have no DTCs stored, and the power take off (PTO) must be disengaged. The message center will display the exhaust soot load as a percentage, indicate the exhaust is full, or indicate the exhaust is overloaded. When the exhaust is full, the message center will allow the operator the option to command a manual regeneration. Additionally, operator commanded regeneration may be cancelled at any time by pressing any pedal or shutting down the engine.
