METER / GAUGE / DISPLAY  METER / GAUGE SYSTEM(for 12.3 Inch Display)  Engine Oil Level Sensor Circuit  

The combination meter assembly and engine oil level sensor are connected via direct line. The combination meter assembly determines the engine oil level based on the engine oil level sensor status signal.

HINT:

The coolant temperature signal and engine speed signal is sent from the ECM to the combination meter assembly via CAN communication. Because an accurate engine oil level cannot be detected when the engine is cold or operating at high speeds, warning control is only performed after the engine is warmed up and the engine is stopped or idling.

NOTICE:

·

When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.

·

When replacing the combination meter assembly, update the ECU security key.
