3. Manual clearing is possible while in the
diagnostic display mode and after the condition
causing to code is corrected (output speed
must be zero).
a. To clear all active indicators, hold the
MODE
button down continuously for 3 seconds until
the shifter tone sounds for 0.5 seconds.
b. Release the
MODE
button to return to
normal operating mode. If the condition
causing the code was not active at the time,
the active indicator will turn off.
Caution:
If clearing a code while locked in a
Forward or Reverse position (fail-to-range), the
transmission will still be in Drive or Reverse
when the clearing procedure is completed.
Neutral must be manually selected.
Exiting the Diagnostic Display Mode:
The diagnostic display mode can be exited by
any of the following procedures:
1. Press the
↑
and
↓
(upshift and downshift)
buttons at the same time on the push-button
shifter.
2. Press any range button,
D
,
N
or
R
, on the
push-button shifter (the shift will be
commanded if it is not inhibited by an active
code).
3. Do nothing and wait until the calibrated time
(approximately 10 minutes) has passed and
the system automatically returns to the normal
operating mode.
4. Turn off power to the ECU (turn off the vehicle
at the ignition switch).
5. After the clearing the active indicator procedure
described above has been performed.
Clearing Records from the Code List
In Memory
If the requirements for Manual Clearing the Ac-
tive Indicator have been satisfied, and the
"MODE" button is held down continuously for ten
seconds while in the display mode until a tone
sounds, all diagnostic records in the code list
that are not active will be cleared and the re-
maining records will be moved up in the code
list.
Abbreviation Found in the Code
Chart
The following responses are used throughout the
following chart to command safe operation when
diagnostic codes are set.
DNS (Do Not Shift) Response
• Turn off lockup clutch and inhibit lockup
operation.
• Inhibit all shifts.
• Turn on
DO NOT SHIFT
light.
• Pulse the tone generator for 8 seconds when
the condition is first detected.
• Blank the select digit in the display.
• Ignore any range selection inputs and disable
the button feedback tone for the push-button
shifter.
SOL OFF (Solenoid Off) Response
All solenoids are commanded off (turning
solenoids
A
and
B
off electrically causes them to
be on hydraulically).
RPR (Return to Previous Range) Response
When the ratio or C3 pressure switch tests
associated with a shift are not passed, the ECU
commands the same range as commanded at the
beginning of the shift.
NNC (Neutral No Clutches) Response
When certain ratio or C3 pressure switch tests are
not passed, the ECU commands a neutral
condition with no clutches applied.
