Renault Lin bus support

EMU PRO
1

Renault Clio 3RS,

Q1: The alternator uses Lin to the OEM APC, does the pro support this as planning to only use PDM and Pro.

Q2: Does the software/hardware support the OEM TRW Power steering Controller using Can messages?

Thanks

Andy

Hi,

We didn’t work with Clio specifically.
We currently have support for two LIN alternators:

  • Denso 104211-2300
  • FoMoCo H1BT-10300-EC

We don’t have native support for this controller. CAN bus messages might depend on the vehicle in which this controller is used. If you have a description of the required CAN messages, we can make it work.

NXP

Thank you for replying so quickly.

I found that NXP supplies for most major manufacturers for the alternators.

There are a few LIN versions. I’m wondering how to find out or identify the type. So you said you support Denso; do you know what LIN version?

Link to the LIN DOC: NXP LIN Decoded

I have an LIN controller. I’ll try and find out the protocol Clio uses. I’m assuming the OEM on these is Valeo. Any tips to sniff the would be great

I’ll also find the CANBUS messages for the steering column.

We have plans to add all these LIN configurations (or even more), but can’t say when it would be ready.

You can try to select FoMoCo model, it uses LIN1 B configuration and I believe it is the most common one. Version and speed depends on a car manufacturer. I suppose speed would be 10400 or 19200, with both LIN versions it makes 4 most probable cases.

Denso 104211-2300 does not use any of the typical configurations.

If you can log the communication we can make it work. If it would use custom configuration, it may require additional tests.

Thank you, I’ll have a look this weekend … on the subject if we we can’t get it to work, Ill buy a other non LIN unit.. a self regulated version . Best way to wire this? Ideally I want to use the Pro ecu but I could go back to black..

Without LIN communication it would work on a default configuration, LIN is not essential for alternator operation.

Since alternators have GND and +12 V always connected, it just need one additional wire for the LIN.
