TCM installed in inside Automatic transmissiom with E-module. Temperature sensor detects temperature increasing for inside of TCU and prevent from obnormal operation of TCU.
TCM set this code If Temperature sensor detects over 140℃.(MIL OFF)

•
Reverse : Shift lock(Push "Unlock button → possible to shift) (priority :4) |
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.
