Clearing the Active Indicator and
Code Records from the Code List in
Memory:
If the conditions causing a diagnostic code to be
set are cleared, the Active Indicator can be
manually cleared by holding the
MODE
button
down continuously for 3 seconds until a tone is
heard from the shifter. To clear code records
from the list, hold the
MODE
button down con-
tinuously 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.
Code Reading and Code Clearing
Procedures
Diagnostic codes can be read and cleared by
two methods: by using the Pro-Link 9000 DDR
plugged in receptacle located on L.H. lateral
console or by using the shifter display. The use
of the Pro-Link 9000 DDR is described in the in-
struction manual furnished with each tool. The
method of reading and clearing codes described
in this section refers to only entering the Diag-
nostic Display Mode by the proper button.
The Diagnostic Display Mode may be entered for
viewing of codes at any speed. Codes can only
be cleared when the output speed = 0 and no
output speed sensor failure is active.
The following descriptions explain how to use the
shifter to read and clear codes:
Reading Codes:
1. Enter the diagnostic display mode by pressing
the "
↑
" and "
↓
" (upshift and downshift arrows)
buttons at the same time on the push-button
shifter.
Note:
If a
DO NOT SHIFT
condition is present
at this time, the lever should be in the same po-
sition as it was at time of code detection. If not,
this shifter tone will sound continuously.
Note:
If an oil level sensor is present, then oil
level will be displayed first. Diagnostic code dis-
play is achieved by depressing the upshift and
downshift arrows or display mode button a sec-
ond time.
2. Read the first code in the first of five code
positions on the digital display of the shifter.
For example, we will read code 25 11 in the
first position. The display will change every two
seconds as follows:
a. Code list position --
d1
b. Main code --
25
c. Sub code --
11
d. Display will repeat cycle of a., b. and c.
above
3. Press the
MODE
button momentarily to view
the second position (
d2
) in the same way as 2.
above.
4. To view the third, fourth and fifth positions (
d3
,
d4
and
d5
), momentarily press the
MODE
button as explained above.
5. Pressing the
MODE
button momentarily after
the fifth position is displayed will cause the
sequence of code positions to start over with
the first position.
6. Any code which is active will be indicated by
the
MODE ON
indicator (active indicator) being
turned on while in that code position (while in
the normal operating mode, the
MODE ON
indicator is turned on to indicate
PERFORMANCE
mode operation, (refer to
Function of the mode button
, on page 2-16)).
7. 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
will also not contain any codes.
Clearing Codes:
1. Clearing of the active indicator is automatically
done at ECU powerdown on all but code 69 34
(see code list, page 5-14).
2. Some codes will clear the active indicator
automatically when the condition causing the
code is no longer detected by the ECU.
