LIN Connection

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.

BSS Connection

BSS Connection

BSS stands for Bit Synchronous Single Wire. There are 3 different BSS signals. The difference between them is the ability to show different alternator errors: BSS-1 = only shows a mechanical or an electrical error BSS-2 = only shows a mechanical or an electrical error BSS-3 = only shows a mechanical and electrical error

VWConnection

VWConnection

We investigated the possibility to find out the connections of an alternator, by checking the position of the sliders inside the so called "VW connectors" and it is possible.

C Connection

C Connection

The C-connection you can find in alternators from car brands like Toyota and Honda. Mostly you can recognize the c-connection by the square and oval shape plug.

COM Connection

COM Connection

Modern type alternators have a COM connection. Below you will find more information about these connections and the protocols.

DFM Connection

DFM Connection

DF(M) stands for Digital Field Monitor. Every alternator brand has a different abbreviation for the DF(M) connection, for example: FR (Field Return), DF (Digital Field), DFM (See above), M (Monitor), LI (Load Indicator). They all function in the same way.

PCM Connection

PCM Connection

The PCM (Powertrain Control Module) is used in Europe on Ford and Land Rover applications. The signal works in the same way as the DFM signal, but now the car ECU is sending this signal to the regulator to change the VSP (Voltage Set Point) depending also on the battery state (AS) and the load (LI) at that specific moment.
