Illumination of the CHECK TRANS light is accompanied by a flashing dis-
play 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 with reduced
capabilities. Before turning the ignition off, the transmission may be operat-
ed 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 for damage to the transmission.
When the CHECK TRANS light comes on and the ignition switch is
turned off, the transmission will remain in N (Neutral) until the condition
causing the CHECK TRANS light is corrected. Generally, while the CHECK
TRANS light is on, upshifts and downshifts will be restricted and direction
changes will not occur. Lever and push-button shift selectors do not respond
to any operator shift request while the CHECK TRANS light is illuminated.
The lockup clutch is disengaged when transmission shifting is restricted, or
during any critical transmission malfunction.
Diagnostic Codes
The diagnostic codes are numerical representations of malfunctions in the
transmission operations. Each code is a two digit main code and a two digit
sub code. The codes, when detected, are logged in the ECU memory. These
codes will fall in two classes: active and inactive. Active codes are codes
currently effecting the ECU process. Inactive codes are retained but may not
effect the ECU process. The diagnostic mode must be entered. A maximum
of five codes, D1 to D5, may be listed at one time. The highest priority code
will be listed in D1. The MODE button will enable selection of sequential
codes.
• Enable Diagnostic Code Selection Display
• Stop the motorhome at a safe location.
• Apply the parking brake.
• Simultaneously press the up and down arrows twice to enter the stored
codes. The first time the arrows are pressed will indicate the oil level
sensor information.
• The codes will display one digit at a time.
• The mode button is pressed to scroll through the codes.
• Any code obtained should be noted and reported to an Allison Service
Center for evaluation and possible repair.
• Inactive codes can be cleared by holding the MODE button for approx-
imately 3 seconds. Some codes are self clearing while others will
require service or ignition cycles to clear.
