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.
Engine Overheated Stop Engine
The radio activates an audible warning as requested by the instrument panel cluster (IPC). The IPC sends a class 2 message to the radio indicating the chime duration of 4 pulses. The warning sounds and the appropriate indicator illuminates in the driver information center (DIC) when the following occurs:
- The IPC determines that the coolant temperature is greater than 127°C (261°F). The IPC receives a class 2 message from the PCM indicating coolant temperature.
- The IPC turns OFF the message when the engine coolant falls temperature below 125°C (257°F). Then displays the ENGINE COOLANT HOT IDLE ENGINE message.
