The Output Speed Sensor outputs pulse-signals according to the revolutions of the output shaft of the transmission. The Output Speed Sensor is installed inside transmission. This value, together with the throttle position data, is mainly used to decide the optimum gear position.
The TCM sets this code if the calculated value of the pulse-signal is noticeably different from the value calculated, using the Wheel Speed Sensor output.(MIL ON : 2 driving Cycle)

(priority : 3)
The function with the higher priority will aiways take precedence. However, a low-priority is not overruled by a higher priority function.
Functions from different priority categories can also run in parallel. It is important to note which function will take precedence in this case.
In such an event it is possible for a substitute function with low priority not be carried out if a second, higher-priority function is present. This has been taken into account when compiling the priority list and is international.
The mechanical emergency run function must always have the highest priority, since from the electrical standpoint it is the only safe condition.
