406 Door Lock Replacement

Model: All 406 Models without dead locking up to DAM 8575.

Vehicles from DAM 8576 are fitted with a newly designed door lock actuator. This modified part will also be supplied as a replacement part for all earlier models. It is therefore necessary to replace the 9-way connector with a 6-way connector every time a lock is replaced.
This document provides the information for terminal matching from old to new. See the tables below.

Please note! Any vehicle with a DAM 8576 or higher should not require the modification.

 

Unfortunately we have not yet been able to accurately identify the central locking systems used by DAM numbers. At this stage we are aware of 2 options for matching the terminals. (Similar to the 306) At this stage we can only recommend to use the green table for late model vehicles and the blue table for early models with infrared remote control.
We will update this information as soon as possible.
