LIN Connection

Recently we have developed new LIN protocols and reorganized them for use on several Motoplat testers. The LIN signal will be now displayed from LIN_1 to LIN_21 together with its ID code. If new LIN protocols appear on the market, we will add more numbers if needed. We did this to make development in remanufacturing easier and cheaper and more clear for customers. Again, you don't need to have a regulator for every alternator, just arrange the regulators in groups or ID codes.

So if you know that LIN-2 is used on Mercedes and VW, you just choose the cheaper one and it is compatible and will save money and storage space.

LIN-1 and LIN-2 Protocols are used from 2002 up to 2011. Regulators LIN-1 and LIN-2 with different codes cannot be interchanged: LIN-1 has to be replaced by LIN-1, the same with LIN-2. All the others above LIN-2 have different systems and baud rates, so they cannot be interchanged. The code that shows up on the screen is the identification code of the regulator which is sent to the ECU to be identified. So to say, they are speaking the same language.

This is where the protocol(ID) will appear, for example: BMW LIN-Infineon or new Valeo CG series alternators. If you check an alternator and on the screen a LIN-4 (Honda) protocol shows up, but isn't a Honda alternator, it means it is controlled by the same protocol. It is not possible to interchange BOSCH and VALEO alternators with the same LIN protocol, because they use different addresses(ID), so it will not work on the car!
