TECHNICAL INFORMATION
Reading Codes
Read codes as follows:
Enter the Diagnostic Display Mode by pressing
both the "
" (up arrow) and " " (down arrow)
push buttons at the same time, twice on the
push-button Shift Selector.
Note: To obtain the oil level, press the " " (up
arrow) and "
" (down arrow) push-buttons once,
at the same time. Refer to "Oil Level Sensor
(OLS) Codes" in this chapter.
Read the first code in the first of the five code
positions on the digital display of the Shift
Selector. For example, code "25 11" is stored in
the first position. The display will change every
two seconds as follows:
• Code list position = "d1"
• Main code = "25"
• Sub code = "11"
Display will repeat steps a, b and c.
Press the MODE button momentarily to view the
second position (d2) as described in step 2.
To view the third, fourth and fifth positions (d3,
d4 and d5), momentarily press the MODE button
as explained above.
Pressing the MODE button momentarily after the
fifth position (d5) is displayed will return the code
display to the first position (d1).
Any code which is active will be indicated by the
MODE ON indicator (Active Indicator) being
illuminated while in that code position. While in
the normal operating mode, the MODE ON
indicator is illuminated to indicate the
ECONOMY mode operation. Refer to "Controls
& Instruments" chapter under MODE.
Any code position in the list which does not have
a diagnostic code logged will display "- -" for
both the Main and Sub Code displays. All
positions after a code position without any code
stored will also display "- -".
Clearing Codes
Clearing of the Active Indicator is automatically
done at ECU power-down for all codes except
code "69 34".
Some codes will clear the Active Indicator
automatically when the condition causing the
code is no longer detected by the ECU. Refer to
the "Diagnostic Code List and Description" table
in this chapter.
Manual code clearing is only possible while in
the Diagnostic Display Mode (output speed must
be zero) and after the condition causing the
code is corrected.
To clear all Active Indicators, hold down the
MODE button continuously for 3 seconds until
the Shift Selector tone sounds for 0.5 second.
To clear code records from the list, hold the
MODE button down continuously for ten
seconds until a second tone sounds. All
diagnostic records in the list that are not active
will then be cleared and the remaining records
will then be moved up the list.
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 go out.
Note: If clearing a code while locked in a drive
(D) or reverse (R) position (fail-to-range), the
transmission will still be in drive (D) or reverse
(R) when the clearing procedure is completed.
Neutral (N) must be manually selected.
Exiting The Diagnostic Display Mode
The Diagnostic Display Mode can be exited by
any of the following methods:
• Press the "
" (up arrow) and " " (down
arrow) push buttons at the same time on the
push-button Shift Selector.
• Press any range button, "D", "N" or "R" on
the push-button Shift Selector (the shift will
be commanded if it is not inhibited by an
active code).
• Do nothing and wait until the calibrated time
(approximately 10 minutes) has passed.
The system will automatically return to the
normal operating mode.
• Turn off power to the ECU (shut off the
engine with the ignition key).
• After clearing the active indicator as
described in "Clearing Codes" section.
DIAGNOSTIC CODE RESPONSE
The following responses are used in the
"Diagnostic Code List and Description" table to
command safe operation when diagnostic codes
are sent.
DNS - Do Not Shift Response
• Release lock up clutch and inhibit lock up
operation.
