International DT466 – ELECTRONIC CONTROL SYSTEMS DIAGNOSTICS – ECL Sensor (Engine Coolant Level)

The ECM monitors engine coolant level and alerts the operator when coolant is low. The ECM can be
programmed to shut the engine off when coolant is low.
The ECL system includes the Electronic Control Module (ECM) and the engine coolant tank with a coolant level sensor. The ECL switch is used in the plastic deaeration tank.

Coolant level monitoring is a customer programmable feature that can be programmed by the EST. The
coolant level feature is operational if programmed for 3-way warning or 3-way protection. The feature can not be enabled if the ECM was not factory programmed for 3-way protection.
