Coolant Level Detector Sensor
The coolant level detector sensor is a stainless
steel probe immersed in the coolant. It is located
on the side of the radiator. It does not fail or wear
out, but may fail to conduct current if it is dirty.
The sensor will no longer conduct current to
return a signal to the controller if the coolant level
drops too low in the radiator. After 30 seconds,
the controller will record Message Code 108. Test
the coolant level sensor if the controller records
Message Code 108 and the radiator is full of
coolant.
Figure 46: Coolant Level Detector Sensor
Sensor Test
1. Ground the sensor to chassis ground with a
jumper wire.
2. Attempt to clear Message Code 108 from the
controller by acknowledging it.
•
Check to see if Message Code 108 clears
by turning the On/Off switch OFF and
then back ON. Wait 30 seconds to see if
Message Code 108 reappears.
•
If Message Code 108 reappears, test the
wire harness for continuity. Also test the
controller.
WARNING: DO NOT remove the radiator
cap from the radiator fill neck when the
engine coolant is hot.
