If the contents of the display are as shown then the coding is successful.

If an incorrect code number has been entered and accepted by the control unit (e.g. 04096), a display will subsequently follow indicating that no communication has taken place with for example rear door control unit.

Indicated on display:

Door control unit BF0022 →  No answer

-- Repeat coding.

If the code number entered, is not accepted by the control unit, the display will show:

Indicated on display:

FAULT →  Coding 00200 not accepted

In this case the control unit has not been programmed with the relevant data for the vehicle.

A check must then be completed to see if the correct control unit for the vehicle has been installed (compare Part No. and letter index), or whether an incorrect code number has been entered.

-- Repeat coding.

If the control unit cannot be coded (correct control unit, correct code number), the control unit is faulty.
