Monitor Description

WARNING: This page is about a different car, the 2021 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

If the engine switch is on (IG) or the engine is running and the current operating state and target operating state of the flow shutting valve (for heater control) do not match, the ECM determines that there is an open or short in the flow shutting valve (for heater control) circuit and stores a DTC.
