Confirm entry with the "Q" button. The control module identification number will be displayed with the appropriate index letter, the code number and the workshop code. if the contents of the display are as shown then the coding is successful.
NOTE: If the code number entered is not accepted by the control module, the previous coding will appear in the display. If this happens, a check must then be completed to see if the correct control module for the vehicle has been installed (compare part number and letter index), or whether an incorrect code number has been entered. Then repeat coding.

NOTE: If after repeating the coding the control module still cannot be coded (correct control module, correct code number), the control module is malfunctioning. Futhermore, at this point the door control module is called-up and checked.
