CHASSIS INFORMATION
DIPLOMAT 2004
The electronic control system of the transmission is programmed to inform
the operator of a problem with the transmission system and reacts automatically
to protect the operator, motorhome and transmission. When the Electronic
Control Unit (ECU) detects a
DO NOT SHIFT
(DNS) condition the ECU
restricts shifting, turns on the
CHECK TRANS
light in the instrument panel and
registers a fault code.
NOTE: For some problems, fault codes may be registered
without the ECU activating the CHECK TRANS light. An
Allison Transmission authorized service outlet should be
consulted whenever there is a transmission related concern.
They have the equipment to check diagnostic codes and
correct problems which may arise.
Each time the engine is started the
CHECK TRANS
icon will light, then
turn off after a few seconds. This momentary lighting is to indicate that
the status light circuit is working properly. If the
CHECK TRANS
light
does not illuminate during start up, or if the light remains on after start up, the
transmission system should be checked immediately.
Continued illumination of the
CHECK TRANS
light during vehicle
operation (other than start up) indicates that the ECU has signaled a
diagnostic code. Illumination of the
CHECK TRANS
light is accompanied
by a flashing display from the shift selector. The shift selector display will
show actual range attained and the transmission will not respond to shift
selector requests.
Indications from the shift selector are provided to inform the operator that
the transmission is not performing as designed and is operating at reduced
capabilities. Before turning the ignition off, the transmission may be operated
for a short time in the selected range in order to “limp home” for service
assistance. Service should be performed immediately in order to minimize
potential damage to the transmission.
When the
CHECK TRANS
icon illuminates the keypad will not
respond to command and the transmission generally will downshift to 4th
gear. The torque converter will not "lock-up" and engine speed is
automatically reduced. Direction changes (i.e. forward to reverse) will not be
allowed. Locate a safe secure place to park the motorhome. If the engine is
shut off, then engaged after a
CHECK TRANS
indication, the transmission
remains in Neutral until the fault causing the
CHECK TRANS
light has
been corrected.
