CONTROLS AND INSTRUMENTS
Baggage Bay Unlocked
06387
Illuminates when one or more bays
are unlocked.
Antilock Brake System
06272
Illuminates when the ABS
is not
a
vailable or when the ABS is
malfunctioning. Since the ABS
system does not operate under 4
mph (7 km/h), the indicator will
remain illuminated until the coach
reaches that speed. Refer to
"Other Features" chapter.
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 IV Diagnostic Codes".
Check Transmission
06282
Illuminates when the ignition is
switched ON. The i
ndicator light
should go out once the engine
starts.
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 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 "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.
For vehicles equipped with the Eaton
transmission, an audible alert will sound when
the transmission fluid reaches 275
o
F (135
o
C).
Refer to Safety Features and Equipment
chapter.
Kneeling / Hi-Buoy Active
06448
Illuminates when Kneeling or Hi-
Buoy is active. An audible alert
also
informs the driver during
operation. Refer to Safety
Features and Equipment chapter.
Top Alternator
06276
Illuminates when the upper
alternator is not charging.
Fuel Filter/Water Separator
06291
Illuminates when accumulated
water in the optional fuel
filter/water separator
needs to be
drained.
Refer to Care and
Maintenance chapter.
