Engine Coolant Indicator

Engine Coolant indicator
ENGINE COOLANT HOT IDLE 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 (DIG) when the following occurs:
^ The IPC determines that the coolant temperature is greater than 125°C (257°F). The IPC receives a class 2 message from the PCM indicating coolant temperature.
^ The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
^ The IPC turns OFF the engine coolant indicator when the engine coolant falls below 122°C (252°F).
