Temperature Gauge: Description and Operation
WATER TEMPERATURE GAUGEThe water temperature gauge indicates the engine coolant temperature.
- ECM converses a signal from engine coolant temperature sensor to engine coolant temperature signal, and transmits to unified meter and A/C amp. with CAN communication.
- Unified meter and A/C amp. transmits engine coolant temperature signal to combination meter with communication line.
- Combination meter converses engine coolant temperature signal to the angle signal, and commands to water temperature gauge.
