[BRUNOXXX]

hello everyone guys,
I have a problem with an ecu renault scenic airbag:
Temic 285580731R

does not communicate in the diagnosis.
I tried to reset crash, but it's the same.

Thank so much

Hi,
Check power, ground and CAN. If it's all ok, change it as i did myself many times on those cars!

thanks,
you wouldn't have the power of the pinout. I think it's a bad module

Yes, please give me VIN or year and i'll try to find it.

By the way this one : 7 + ignition, 18 ground, 10 and 11 CAN.

this is VIN : VF1JZ0L0641732194
year 2009
thank you

Re,
You should find two connectors: little black / big yellow

Beware NOT to move or smash Airbag ECU when ignition is ON and ECU not fixed to car with his screws

Big yellow:
+ ignition ( 12V of course) on PIN 12

Little Black
Ground on PIN 75 (check it with test lamp 21W to 12V)
CAN H on PIN 19 (you should find with ignition on about 2,4V on DC voltmeter to the ground)
CAN L on PIN 18 (-------------------------------------2,2V-----------------------------)


Or have a look here with pictures, at the first page:
