Technical stilo eps dtc's

[furthorc]

hi

i have these dtc's on stilo 1.2 16v 2002
steering working,warning light goes off after system check
i need to access the circuit diagram for eps before i even
know where to check ...........anyone have any advise on best approach
im hoping its a continuity issue on connectors rather than component
failure but finding any spec is proving to be difficult
fresh ideas needed.dtc's list below

Multifunction (Power steering - Diagnose)
DTC Description
C1001 - Battery voltage
- Intermittent
U1002 - CAN line error

Have you been to the download section and downloaded the Stilo eLearn? I think wiring diagrams are in there.

With those faults, the first things you need to check are the battery and battery connections including earth leads and fuses on battery connector.


Then at EPS connectors.

hi again.replaced new battery recently also did amp draw test which was 0.20A After cleaning the main connections brought it down to 0.02A. CLEANED ENGINE FUSE BOX AND ALL CONNECTORS THAT LAY UNDER IT.THE TWO ECU PLUGS.CHECKED FUSES F2,F24.
yes need to remove steering column panels to access EPS Module connections,can i do that without removing steering wheel as it looks as if lower cover is under rim of steering wheel bose.took out the 3 hex screws but couldn't split it apart anyone tackled this ??
i noticed 'CITY' button does not bring dash light on and appears to have no effect where i remember it once did. found a circuit diagram on elearn.......not the best but gives some idea.thanx for response so far
