Audible Warning Device: Testing and Inspection
Engine Temperature High and Critical Chime
The engine temperature critical chime will warn the driver that the vehicle's engine is overheating. While monitoring the coolant temperature, the
Powertrain Control Module (PCM) will send on the CCD bus as engine temperature every 1.376 seconds to the Body Control Module (BCM). The
BCM calculates engine temperature and determines if a warning should occur. This feature is functional only with the Ignition Switch in the
RUN/START position.
When the engine temperature reaches 122 °C (252 °F) the BCM will chime one tone and the engine temperature lamp comes ON. The BCM turns OFF
the lamp when the engine temperature reaches 117 °C (242 °F). The BCM will chime continuously when the engine temperature reaches 125 °C (257 °
F). The chime will turn OFF after four minutes or when the temperature reaches 117 °C (242 °F), which ever occurs first.
