CHECK COOLANT LEVEL
The IPC monitors the engine coolant level through the engine coolant level switch. If the IPC detects ground at IPC connector C2 terminal Ab, the IPC
displays the CHECK COOLANT LEVEL message after filtering for vehicle speed and acceleration. The IPC sends the information to other modules
through a class 2 serial data line.
