All Models - Tip for Replacing a Control Module
If any vehicle control module is replaced for any concern, it is recommended to code that module according to guided fault finding before testing if the repair was successful. For example, if a door module was replaced for a battery drain, then that module must be coded before retest of the system. It is also recommended to recode the gateway module when another module is replaced to reset the communication system. Even if the coding seems to be correct, entering the code anew will force a reset of the system.
