You need this to read Fiat ECU errors.

I dont have any OBD interface I have only dashboard from Panda controlled by arduino and canbus shield

We are people discussing issues with the cars so it's unlikely anyone here can be much help. But you never know.

The dashboard displays information supplied by the engine ECU. Also, at the first system start the (1) engine ECU, (2) ignition key data chip and (3) instrument cluster are electronically locked together. None of the three will operate when any are disconnected. It's a security feature.

Airbag isn't on the CAN Bus.

KWP I believe.

I have no knowledge of the commands to send or how to sniff for a response.

To lazy to find out when for a few pounds you can buy either an ELM or K-line cable and the software is readably available.

Using ELM or other diagnostic interface have only sense when its connected to ECU.

Using ELM or other diagnostic interface have only sense when its connected to ECU.

The diagnostic connector has more pins than needed for just connecting to the engine module.

Car manufactures use the spare pins to allow connection to the other modules

Below is a list for Vauxhall which may or may not be the same.

2 K-Line ABS diagnostic
3 K-Line Radio, automatic transmission, immobilizer, steering wheel
4 GND Chassis ground
5 GND Signal ground
6 CAN-High, J-2284
7 K-Line Engine, ABS, AT, Airbag, Navigation system, Radio diagnostic
8 K-Line TID, MID diagnostic
9 K-Line ABS, Airbag
11 K-Line Automatic transmission diagnostic
12 K-Line TID, MID, ABS, AirBag, air condition
13 K-Line immobilizer, MID, Airbag diagnostic
14 CAN-Low, J-2284
16 +12V Accumulator


Everything you want to connect to is possible with multiecuscan and the correct cable either switched or with adapters


If you are determined to sniff the signals yourself you will be better asking on a OBDII forum.

Marelli SELESPEED CFC228F Automatic Gearbox module is on pin 7

TRW Airbag 2 module canbus ???????
TRW Airbag MY99 module pin 3

You will need the paid version of multiecuscan for "TRW Airbag 2" and the gearbox

My car has the "MY99" module and can be connected with the free version
