(1) This code is logged to real time to protect the transmission in case a loss of power to the ECU (Power
Interruption code 35 00) occurs.
(2) The ECU hardware or software must be changed so that they are compatible.
(3) Additional codes could be logged for other shifts where X indicates range shifted from and Y indicates range
shifted to.
(4) The COP reset will cleat the active inhibit.

Oil level codes are obtained as follows:
1. Press both the "
" (up arrow) and "
"
(down arrow) push-buttons simultaneously.
Oil level codes are displayed in 2 minutes
(e.g. display will flash and 8, 7, ...;
countdown will occur during the 2 minutes)
once the following parameters are met:
•
Engine at idle;
•
Oil at operating temperature;
•
Transmission in neutral (N);
•
Transmission output shaft stopped;
•
Oil level sensor present and working.
After 2 minutes, the display will flash one of the
codes shown below:
CODE
CAUSE OF CODE
OL-OK
oil level is correct
LO-01
one quart low
LO-02
two quarts low
HI-01
one quart high
HI-02
two quarts high
Note :
Failure to meet one of the above
parameters will stop the two minute countdown.
One of the codes shown below will indicate the
cause of the countdown interruption. Once all
parameters are met, the countdown will continue
from where it left off.

Clearing Codes
If the CHECK TRANS light is illuminated, first
clear all diagnostic codes by pressing both the
"
" (up arrow) and "
" (down arrow) push-
buttons at the same time, twice.
Take the motorcoach for a test drive. If the
CHECK TRANS light illuminates again, record the
diagnostic codes. Refer to "World Transmission
(WT) Diagnostic Codes" under "Reading Codes".
