Hello i have lancia y 840 2003 year 1.2 8v engine 188a4000. Today i fiddled with the instrument panel looking a way to install rpm gauge since mine doesn't have one and when i put everything back together my airbag light stays on when i start the car. What did i do wrong and how can i fix it i yried conections and everything but no luck. Also how can i install rpm gauge i tried over the negative pole of the egnition coil but it reads half the value. I have read that there is a blue wire in the computer harness and thats where i can connect the rpm gauge but i need points from someone with experience. Thank you.

Lancia y 840 airbag light on and how to instal rpm gauge
Hello,
have you disconnected the battery when playing with the cables and connectors?
have you disconnected the battery when playing with the cables and connectors?
Is the mileage blinking? or do you see any other strange behaviour?
No absolutely everything else is normal. I am thinking that maybe it was a mistake running the car without the instrument panel hooked up.
I'm afraid you can be right. The cars now are wheeled computers in fact.
The FIAT airbag module is very sensitive to voltage fluctuations, drops etc. There are many known cases that it needed a specialized repair after playing with the connectors (however mostly of the ones related with the security systems - airbags and pretensionners) or battery. However this might not be the case.
I'd first try to disconnect the battery safely for some time (ignition key out, all cables and connectors in place, all receivers switched off, all doors closed - of course bonnet up, as I assume the battery is in the engine compartment, let the electronic modules shut down, so leave it for a minute or two, then remove the negative terminal from the battery), unless you tried and described in post #3. Reconnection in the same way.
Then, if the warning light does not goes off, I'd suggest connecting to MultiEcuScan or AlfaOBD, they are able to connect to the airbag module with the required adapter (list of supported modules and necessary equipment on the multiecuscan.net website). And then check for the errors, clear all of them. And recheck
Attached is the eLearn documentation that contains the instrument panel (page 25) and the airbag modules (page 79).
It could be also useful to discover if the LS/LX versions instrument panel could be installed in place of the LE one.

Thank you very much for the help and instructions you provided me. I will try and get back to you. Kind regards to you.I'm afraid you can be right. The cars now are wheeled computers in fact.

Just to inform you i took the car to fiat dealer and with official software they deleted the airbag light for less than 10 euro. That is solved i now only have to figure it out how to instal 4 stroke rpm gauge or buy a 2 stroke rpm gauge but i will leave the fiddling for now as it is. Thank you for your support.
