## Wiring Diagram

.

1 | Instrument cluster
2 | Water temperature gauge
3 | Microcomputer

## Operation

• The PCM outputs the coolant temperature signal to the microcomputer in the instrument cluster via serial communication.
• The microcomputer outputs the display signal to the water temperature gauge based on the input coolant temperature signal to control the gauge.
