Driver Information Center: Description and Operation
Coolant Level Information
Coolant level information is received by the PCM from the low coolant switch. If the low coolant switch returns a signal indicating a low coolant
condition, the PCM transmits a low engine coolant message to the IPC over serial data. The IPC then transmits the information to the DIC and the DIC
displays the LOW ENGINE COOLANT message.
