Multiecuscan

Hi,

i got a fiat bravo 1.4sx mj97 with bosch motronic ecu..

i cant use fiatecu because my ecu is not supported yet.. so i justed kwp71diag from sander to get connection to ecu.
today on the highway i noticed loss in engine.. no more power.. but no engine lights or sounds or so.. so i stoped car.. switched off.. started new.. all fine..

So Kwp71diag gives me:

Read diagnostic faultcodes :

Could any1 please tell me what these 2 error codes mean ? it is Bosch Motronic MA1.7.3

Hi,

I think that these 2 errors mean the following:
1. Rpm sensor, Intermittent
2. Lambda sensor, S.C. to Ground

However, I'm not 100% sure about this because these old ECUs use weird protocols and data formats.

Thanks a lot..
by the way.. u check viewtopic.php?f=6&t=521&start=10 ?
I uploaded FIAT 9141 STANDARD.pdf that would help you to implement these ECUs
