The park brake is not engaged.Submode 6.11 (Retarder Calibration)
For 725 and 730 OnlyThis mode allows the service person to perform the retarder calibration. When this mode is entered, the service person is intending to start the retarder calibration. When the service person holds down the "C" switch input for 2.0 seconds the ECM will start the calibration. When the calibration starts, the leading characters "rc" will flash, and the calibration will start.If the conditions are not correct, or if the calibration results in an error condition, the display will show a reason for the problem. The following is the list for this calibration:
"E01" Active Diagnostic
"E04" Shift Lever Not In Neutral
"E07" Service Brake Engaged
"E08" Park Brake Not Engaged
"E10" Transmission Output Speed Too High
"E11" Transmission Oil Temperature Below Limit
"E12" Transmission Oil Temperature Above Limit
"E13" Latching Pressure Low
"E14" Calibration Failure
"E15" Calibration Aborted By ECM
"E16" Calibration Out Of Range Low
"E17" Calibration Out Of Range High
"E99" Undefined Error

The shift lever is not in neutral.Submode 6.12 (Transmission Stall Service Test)
This mode allows the service person to perform the transmission stall test. When this mode is entered, the service person is intending to start the service test. When the service test starts, the leading characters "sc" will flash and the service test will start. While the service test is active, the ECM will override the transmission gear to the top gear of the machine. The override will stay active until a setup condition is no longer met, or the gear has been overridden for 15.0 seconds.The service person should fully depress the throttle and observe the stall engine speed. This will give a measure of the performance of the engine.If the conditions are not correct, or if the service test results in an error condition, the display will show a reason for the problem. The following is the list for this service test:
"E02" Incorrect Throttle Position
"E03" Test Timed Out
"E04" Shift Lever Not In Neutral
"E06" Service Brake Not Engaged
"E08" Park Brake Not Engaged
"E09" Torque Converter Output Speed Too High
"E10" Transmission Output Speed Too High
"E99" Undefined ErrorIf there is no error condition, then the display will show the value of the engine output speed.
