Service codes are indicators of faults with the electronic systems. Codes do not control the machine and clearing codes will not fix any issue.

The number 113 is relating to the transmission errors, the numbers after it are the fault code and cause codes. (113 then 299.12 for example) If the words SERV CODE are present when you are scrolling thru the codes, it means that is an active code. If it is not shown, it is logged codes from memory.

113 are transmission codes, 036 are engine codes and 030 is for the monitor codes.

Please record all the codes again and post them here, I will be glad to help more with that information.
