Instrument Panel and Indicators
Transmission Oil Filters
The Transmission Oil Filters Monitor lamp
(13, Figure 3-9) will illuminate if the trans-
mission controller detects that a trans-
mission filter is restricted, or that the wire
between the controller and the switch is
cut or broken.
If this lamp flashes and the alarm buzzer sounds, notify
maintenance personnel, immediately.
As soon as practical thereafter, drain the transmission
oil, replace the transmission filters, and check for con-
tamination in the oil.
Lamp Test
The Lamp Test switch (14, Figure 3-9) is a
three position, two function switch. The switch
is spring loaded to the middle, ''neutral'' posi-
tion. If depressed on the right side and held, it
is a lamp test for all of the monitor lamps except the
check engine lamp.
If the left side of the rocker switch is depressed held
the lamp test for the check engine lamp will function.
When the check engine lamp is illuminated because of
a fault in the Centry™ System, depress and release the
left side of the rocker switch. Wait, and the Check
Engine lamp will begin flashing the fault codes.
(Refer to CENTRY™ FUEL SYSTEM DIAGNOSTICS
later in this section.)
Low Brake Pressure
The Low Brake Pressure Monitor lamp
(15, Figure 3-9) will illuminate if the trans-
mission controller detects that the brake
system hydraulic pressure is below 1850
psi, or that the wire from the switch to the
controller is cut.
Lateral Slope Warning
The Lateral Slope Warning Monitor lamp
(16, Figure 3-9) will illuminate if the dump
body is off of the frame and the lateral
slope of the truck is beyond a pre-set
safety limit.
(This is a tip-over warning device)
Crankcase Pressure
The Crankcase Pressure Monitor lamp
(17, Figure 3-9) will illuminate if the engine
crankcase pressure is greater than
14.5 in. of H
seconds.
At the same time a fault code will be registered in the
Centry™ System. (Refer to CENTRY™ FUEL SYSTEM
DIAGNOSTICS later in this section.)
Panel Dimmer Switch
The Panel Dimmer Switch (18, Figure 3-9)
is used to adjust the brightness of the
lighting inside the monitor panel.
Adjust as follows:
To increase brightness, turn clockwise.
To decrease brightness, turn counter-clockwise.
Engine Oil Pressure
The Engine Oil Pressure Monitor lamp (19,
Figure 3-9) will illuminate if the engine oil
pressure falls below a certain value for a
5 second period of time. That value is
dependent on engine RPM.
At the same time a fault code will be registered in the
Centry™ System. (Refer to CENTRY™ FUEL SYSTEM
DIAGNOSTICS later in this section.)
