Engine Coolant Hot/Idle Engine

The IPC illuminates the ENGINE COOLANT HOT/IDLE ENGINE - 44 indicator in the DIC and sends a class 2 message in order to activate an audible warning when the IPC determines that the coolant temperature is greater than 128°C (262°F). The IPC receives a class 2 message from the PCM indicating the coolant temperature.

The IPC turns OFF the indicator when the engine coolant falls below 125°C (257°F).
