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.
Automatic Engine Idle Shutdown
Vehicles equipped with automatic engine idle shutdown have an instrument panel cluster message and an audible alert that notifies the driver 30 seconds prior to engine shutdown. When the shutdown occurs, the PCM broadcasts a shutdown message and vehicle power is disabled.
Shutdown occurs under the following conditions:
- The vehicle is stationary
- The gear selector is in the PARK or NEUTRAL position or the clutch pedal is released
- The accelerator pedal is released
- The brake pedal is released
- Scan tool is not connected
