Title: METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Tachometer Malfunction; 2019 - 2020 MY RAV4 RAV4 HV [11/2018 - 08/2020]

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.

PROCEDURE

1.

READ VALUE USING TECHSTREAM (ENGINE SPEED)

(a) Using the Techstream, read the Data List.

HINT:

  • When the Data List values of the ECUs match, an internal malfunction of the ECM is suspected.
  • When the Data List values of the ECUs do not match, a signal output error of the ECM or an internal malfunction of the combination meter assembly is suspected.

OK:

The Data List values of the ECUs do not match.
