hi all
fuel pump has been replaced and it looks that' all ok, the only strange thing in that speedo is not working,i went to a mechanic-friend to ask for a brief diagnostic, as a result
it came out
U2106 - CAN-Bus no Communication with Transmission Control Module(00) - Present
but the car has no automatic transmission.
so we checked can bus config and variant config in ecm module.
in the variant tcm was disabled but in canbus it was enabled.
checked abs-tc variant is the same as ecm but hi speed can bus is completely different.
so i called the workshop with tech2 that have done the job, and take back the car, he have done the sps reprogramming (the configuration has misteriosly "shifted"), with no charge. (solved dtc from TCM)
now i've rechecked the variant/ hi speed can bus from ecm and as a result we have a completely new and different can bus config that doesn't match the other modules .
now i have on ecm canbus config
ECM NOT PRESENT
TCM NOT PRESENT
ABS/TC/ESP NOT PRESENT
EHPS PRESENT
CIM NOT PRESENT
YRS PRESENT
AHL/AFL NOT PRESENT
CDC NOT PRESENT
and in ABS/TC/ESP (SAME AS CIM)
ECM PRESENT
TCM NOT PRESENT
ABS/TC/ESP PRESENT
EHPS PRESENT
CIM PRESENT
YRS PRESENT
AHL/AFL NOT PRESENT
CDC NOT PRESENT
in the car there is abs/tcs, there is cim, and ehps ...
i'm really confused and don't know if there is a possible security issue for abs or airbag or whatever.
The question is: the hi speed can bus have to be the same for all ecus, ecm,abs, cim etc. ?
the replaced part is bosch pn 0986444030 (used with security code) that should be the same as the broken 0470504217 according to bosh database
additional info:
car was restored after front crash replaced also egr and radiators (engine, intercooler, ac)
other dtc prensent at the moment
CIM - B1012 - Steering Angle Sensor Not Calibrated
(00) - Present
ABS/TC/ESP - C0460 - Steering Angle Sensor not Calibrated
(42) - Intermittent
BCM - B1001 - Program Electronic Control Unit (ECU)
(00) - Intermittent
Thanks
