Controls and Instruments

Check Engine
06281
Illuminates when the ignition switch
is ON as a light bulb check. The
light should turn OFF after five
seconds. If the indicator remains
ON after five seconds or comes ON sometime
after starting the engine, the Detroit Diesel
Electronic Control (DDEC) system has detected
a minor problem.
The indicator light will remain ON until the
malfunction has been corrected.
A diagnostic code will be stored in the memory
and the indicator can be used to identify the
problem. Refer to the "Technical Information"
chapter under "DDEC V Diagnostic Codes".
STOP Engine
06309
Illuminates when the ignition switch
is ON as a light bulb and DDEC
system check. The indicator should
go OFF after five seconds.
If the indicator remains illuminated after five
seconds or comes ON sometime after starting
the engine, the DDEC system has detected a
major problem. Immediately park the coach in a
safe place and stop the engine.
When a problem is detected, the engine power
will automatically begin to decrease gradually,
followed by full shutdown after 30 seconds.
The engine emergency shutdown may be by-
passed by using the "Engine Stop Override"
switch on the L.H. lower control panel.
NOTE
Once the engine is stopped, it cannot be
restarted until the problem has been corrected.
A diagnostic code will be stored in memory.
The STOP engine indicator can be used to
identify the problem. Refer to Technical
Information chapter under "DDEC V
Diagnostic Codes".
Check Transmission
06282
Illuminates briefly when the engine
is started as a light bulb test. The
indicator light should go out after
two seconds.
When the "CHECK TRANS" indicator is
illuminated and the shift selector emits short
beeps for 8 seconds, the electronic control unit
(ECU) is restricting transmission shifting
because special or abnormal conditions are
detected. The control pad display will be blank.
If this happens, drive the coach to the next
available service center to receive assistance.
The ECU will not respond to shift selector
requests since operating limitations are being
placed on the transmission (i.e. upshifts and
downshifts may be restricted). Direction
changes and shifts to and from neutral (N) will
not occur.
Any time the CHECK TRANS telltale light
illuminates, the ECU will register a diagnostic
code. It may be identified on the Allison or ZF
transmission display or by using a diagnostic
tool. Refer to "Technical Information" chapter.
NOTE
The CHECK TRANS indicator may also
illuminate when starting the engine in
extremely cold weather. Refer to Allison
Transmission or ZF Transmission Warm-Up in
"Starting and Stopping Procedures".
Transmission Fluid Temperature
06292
Illuminates when the transmission
fluid temperature is too high.
Disengage the retarder to allow the
oil temperature to cool down.
Windshield Washer or Headlights Washer
Fluid Low
06601
Illuminates when the windshield
washer or the headlights washer
fluid level is low. The washer fluid
reservoirs are located inside the
front service compartment.
WARNING
Do not drive without sufficient windshield
washer fluid.
Fuel Level Low
06286
Illuminates when approximately 12
US gallons (45 liters) of fuel re-
mains in the tank. After the light
comes ON, the remaining fuel will
provide no more than 60 miles
(100 km) of travel. Do not exceed
this distance.
