GF54.30-P-3028GH
Displaying coolant level, function
28.6.99
MODEL
163 as of 1.3.99
Function prerequisite
Engine: ON
Function
If the coolant level drops below the minimum mark the low ECL
indicator lamp (A1p11) is illuminated.
To record the coolant level the instrument cluster (A1) is connected
direct to the
coolant level indicator electronic switch (S41)
via two
cables. The
coolant level indicator electronic switch (S41)
consists of two electrodes.
D
If the
level is correct
both electrodes are immersed in the
coolant. The coolant serves as a dielectric between the
electrodes.
D
If the coolant level is below the minimum mark the electrodes of
the sensor are no longer immersed in the coolant. There is only
air between the electrodes as a dielectric. Evaluation
The instrument cluster (A1) sends test pulses to the sensor for
a period of one millisecond. These pulses are deformed
differently depending on the dielectric (air or coolant).
The instrument cluster (A1) evaluates the pulse shape and, if
the coolant level is below the minimum (electrodes are
completely in air), actuates the low ECL indicator lamp (A1p11)
after a delay of
approx. 60 seconds
.
The delay serves to prevent the indicator lamp flickering due to
the coolant moving from side to side on corners or off-road.
Diagnosis
Diagnosis is carried out, as described in the Diagnosis Manual, via
the simulation of the
coolant level indicator electronic switch (S41)
by a resistance.
