    Default vectra c gsi steering fault

    my 2005 gsi 3.2 has developed an intermittent worsening problem where the power steering fault symbol comes on on the second iginition click even before i crank the engine over and did originally take just one restart to put the light out, now it can take up to 5 restarts and the traction light also comes on and takes 1 more restart to put that out, it doesnt happen every time either when the codes are read its a can/bus communication loss problem and it never fails once started and lights are out, i have done a trip of 3 hours without failure, its only on starting, hot or cold. have checked the pas pump,engine and boot fuseboards and abs pump connectors for corrosion/water/damaged, no faults found.
    Anyone had similar problems, cant seem to find any wiring diagrams to trace the can/bus wiring from the abs and pas pumps to its source in the car where i think it starts its signal ? the codes present are U2103-NP AND U2111-NP

    tonight i tried it again and once again the steering symbol came on before cranking with the other warning lights, the abs light then went into a flash sequence, like code numbers, i thought it flashed 213 and 214 ? does it have a flash code system ? once cranked the second restart corrected the fault and it will not reoccur. thought i couldnt hear the relay clonk in the engine bay board which puts the abs and traction light out first time i tried it, am going to recheck next time its faulting. tried to find a workshop manual with wiring layouts/component positions , ie haynes etc but they exclude the 3.2 model on the up to oct 1995 facelift book. does most of the vectra c vehicles have abs/traction/pas ?

    Default vectra c gsi steering fault

    Did remove the connector on the abs unit and couldnt see any corrosion/water. the fault seems to only effect the power steering operation and the 2 main codes both point to can/bus communication failure on the abs/pas system. trying to find where the signal starts its journey on the can/bus system which i wondered if it was from the cim unit under the steering column ? but cannot find anything anywhere showing wiring routes/layout on my vehicle .
    Wondered if this system is used on most of the other vectra models up to facelift as there is a haynes manual for general vectra c's just not certain engine types including mine.
    Thanks for your comments i will recheck everything people tell me and hopefully i will find the fault. dont think its a component, just a connection somewhere given its characteristics.
