EMS INSTRUMENT CLUSTER CONTINUED
Engine Coolant Temperature Sensor/Warning
A sensor is fitted to the engine to measure the temperature of the engine coolant. The temperature is displayed by means of a
20-segment bar graph (Figure 46, Item 23). The segments of the bar graph are color coded. Segments 1 to 16 will appear
green, segments 17 to 20 will appear red.
When the coolant temperature reaches 208°F (98°C), the warning light (Figure 46, Item 24) on the EMS will illuminate. (Red
segment 17 of the bar graph will also be illuminated.)
If the temperature continues to rise at 214°F (101°C), not only will the warning light (Figure 46, Item 24) be illuminated, but
the internal buzzer will sound, the message "ENGINE TEMP" will be displayed by the LCD, and a warning light on the front
console warning light panel will be illuminated. The internal buzzer can be canceled by pressing the OK button (Figure 46,
If the temperature is allowed to rise any higher, at 221°F (105°C), along with warning light (Figure 46, Item 24), the internal
and external buzzers will sound, the LCD message and the front console warning light will be activated, plus all the segments
on the bar graph will flash. Once this condition is reached, the buzzers can no longer be canceled by pressing the OK button
(Figure 46, Item 5).
