Monitor Description

WARNING: This page is about a different car, the 2020 Toyota RAV4 and 2019 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

The ECM monitors the output voltage while the vacuum switching valve (for active control engine mount system) is operating.

The vacuum switching valve (for active control engine mount system) turns on and off according to ON/OFF switching of a transistor inside the ECM.

If a continuous mismatch occurs between the ECM transistor state and the output voltage, the ECM determines there is a malfunction in the vacuum switching valve (for active control engine mount system) circuit and stores a DTC.
