On Pre '02 cars the coding is slightly different method than Post '02 cars. I am only going to elaborate on coding individual parameters, you can go learn how to code entire modules thru the VO later once you learn the basics below.
The first part to understand is what this stuff about ZCS/VO or "vehicle order" is. When BMW makes a car, they create whats called a "vehicle order", this is basically a bunch of numbers writen into the car that tell what modules are installed in the car, regional info etc. This is like your car's DNA! for example if the car has a sunroof, or a convertible or radio etc etc and that it was meant for US,Canada,France etc. Why is it called ZCS you ask? because its abbreviated german, and its confusing as hell.īecause each car is different with a different set of options/modules or country that its located, the "vehicle order" aka. The VO is written into a couple modules of the car, usually ones that start with an "A", like AKMB or ALSZ. In my 02 M3, the VO was written in ALSZ and AKMB. On my '00 328ci it was stored in EWS, KMB.
Its nothing more than a string of text/numbers stored in the flash memory of these modules, nothing special. Why is it written into two places? because if one module is failed and has to be replaced, then the other will serve as a backup so you can code the new replacement module to your car. For example ALSZ is the "light switch module" in your car, for some reason it fails. When you buy a new LSZ/LCM, you can retrieve all your settings of VO from AKMB and then code your new LCM to YOUR factory settings.
The chances of both modules failing is slim, but if it does. you'll have to contact BMW so they can give you the VO for your car from their records. OK the one difference is pre-02 cars dont have a VO. Those cars have their ZCS (which acts like a VO) stored in the EWS or KMB modules. The stuff below is basically identical however for individual parameter coding.ġ. When you load NCS expert, you need to load a profile. These profiles just change how ncs expert behaves when you read your car.
