Multiecuscan

Hi,

I've a Fiat Barchetta made in 1999 with only the driver airbag; due to the airbag red light bulb on, I decided to make a diagnosis on the TRW airbag ECU, using multiecuscan program; here the results:

==========================================================================================================
01 - Control unit fault | Unknown / Pretensioners impact | Impact occurred | 226
01 - Control unit fault | Unknown / Pretensioners impact | Impact occurred | 92
01 - Control unit fault | Unknown / Pretensioners impact | Impact occurred | 216
01 - Control unit fault | Unknown / Pretensioners impact | Impact occurred | 45
01 - Control unit fault | Unknown / Internal error | Impact occurred / Present | 227
03 - Connection between failure lamp and ECU | Open circuit | Impact occurred / Intermittent | 221
02 - ECU Supply Voltage | Value too low | Impact occurred / Intermittent | 70
0C - Passenger belt pretensioner | Open circuit | Impact occurred / Intermittent | 78
08 - Driver squib circuit | Short circuit | Impact occurred / Intermittent | 189
0B - Driver belt pretensioner | Short circuit | Impact occurred / Intermittent | 189
==========================================================================================================

I'm confused I cannot understand what is wrong; maybe all airbag system is broken; what should I replace, ECU, or pretensioner o airbag on the steering wheel or all of these ?

Any ideas or suggestions ?

Thanks a lot!

if you get error "01" and can't erase errors big chance airbag ECU is faulty. either hardware itself or software is corrupted.
you can try to clear crash see if it helps
