How to Input the Chain and Function
The following shows the Chain and Function input method in the Diagnostic Mode.
A Chain/Function Code must be input as 2 digits. If the Chain/Function Code is "1,"
it must be input as "01." Any input value that goes beyond the 2nd digit will be ignored.
To clear the Chain/Function Code that was input, press the "C" button.
Both digits will be cleared, and you will be returned to the Code input screen.
When inputting the Function Code, pressing the [Start] button after inputting a Function Code
that is out of the specified range will transfer you to the initial screen of Function input.
Enter the Diagnostic Mode and check that the "C_ " (Chain Code input screen) is shown on the

Use the keypad to enter the 2-digit Chain Code.
The first number will appear in the first digit space, and the "_" will move to the right.
