METER / GAUGE / DISPLAY METER / GAUGE SYSTEM(except 12.3 Inch Display) Engine Coolant Temperature Receiver Gauge Malfunction
DESCRIPTION
The combination meter assembly receives engine coolant temperature signals from the ECM via CAN communication. The combination meter assembly displays an engine coolant temperature warning based on the data received from the ECM.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
- 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 any of the following ECUs, update the ECU security key.
-Combination meter assembly*
-ECM
*: except NR Series Engine
·Before replacing the ECM, refer to Service Bulletin.*
*: for Gasoline Model
PROCEDURE
Check if CAN communication system DTCs are output.
