Coolant Level Switch

COOLANT LEVEL
The coolant level switch closes when the engine coolant fluid in the radiator is low. If the ignition switch is in the RUN position and the IPC detects a low voltage condition on IPC connector C2, terminal A10 (CKT 1478, LT GRN). The IPC illuminates the BRAKE indicator, displays the CHECK COOLANT LEVEL message on the driver message center and sends a class 2 message to the radio (IRC) to activate the chime.
