Tachometer Malfunction |
DESCRIPTION
In this circuit, the combination meter assembly receives engine speed signals from the ECM via CAN communication. The combination meter assembly displays the engine speed calculated 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.
