CONTROLS/INSTRUMENTS
2 - 8
10. High Temperature Retarder Oil Indicator
Illuminates when the transmission oil tempera-
ture is too high. Disengage the retarder to allow
the oil temperature to cool down.
11. Do Not Shift Transmission Indicator
(optional)
Illuminates briefly when the ignition is switched
ON as a light test. The indicator light should go
out after two seconds.
When the
Do Not Shift
indicator is illuminated,
and the shift selector emits 8 seconds of short
beeps, this means that the ECU is restricting
transmission shifting because of special or ab-
normal conditions detected by the ECU. The
SELECT
digit on the display will be blank.
If this happens, drive the coach to the next avail-
able service station 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
Do Not Shift
light has been illumi-
nated, the ECU will register a diagnostic code. It
may be identified on the display or using a diag-
nostic tool. Refer to
Technical Information
sec-
tion under
World Transmission (WT) Diagnos-
tic Codes
.
Note:
The
Do Not Shift
transmission indicator
may also illuminate when starting the engine in
extreme cold weather. Refer to
Starting and
Stopping Procedures
section under
Cold
Weather Starting
.
12. Output Retarder
(optional)
Lights when transmission’s output retarder is ac-
tivated. For system description, see page 4-4.
13. Stoplights
Lights when stoplights are activated.
14. L.H. Turn Signal
Flashes when the left turn signal is selected with
the multifunction lever, or when hazard switch is
turned on. (When hazard switch is turned on
both L.H. and R.H. turn signals will flash.)
15. High Beams
Lights when headlight high beams are selected.
16. Engine Compartment Door Ajar
Lights when engine compartment door is ajar.
17. Battery
Lights when alternator is not operating properly.
18. R.H. Turn Signal
Flashes when the right turn signal is selected
with the multifunction lever, or when hazard
switch is turned on. (When hazard switch is
turned on both L.H. and R.H. turn signals will
flash.)
19. Stop Engine
Will light when major engine problems occur.
The engine power will automatically begin to de-
crease gradually and will be followed by an
automatic shutdown after 30 seconds. This 30
second delay period may be repeated using the
Stop Engine Override
switch (page 2-6).
Note:
Once engine is stopped, it cannot be re-
started until malfunction is corrected.
As a light bulb and system check, this indicator
will illuminate when the ignition switch is turned
ON
. After about five seconds, the light will turn
off.
20. Check Engine
Will light if a minor engine malfunction is de-
tected by the DDEC (Detroit Diesel Electronic
Control) system. This includes any situation
where the engine coolant reaches 217°F (103°C)
because of cooling system problems or because
of situations described in
Engine Coolant Tem-
perature Gauge
(page 2-10). This light will re-
main illuminated until malfunction is corrected.
Furthermore, this indicator flashes to indicate
engine malfunction codes when the required
procedure outlined on page 5-9 has been per-
formed.
Note:
As a light bulb and system check, this in-
dicator will illuminate when the ignition switch is
turned
ON
. After about five seconds, the light will
turn off.
