METER / GAUGE / DISPLAY METER / GAUGE SYSTEM(for SFTM Made) 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.

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.

·

Before replacing the ECM, refer to Service Bulletin.

PROCEDURE

1.CHECK CAN COMMUNICATION SYSTEM

a.

Check if CAN communication DTCs are output.
