vectra vxr ids light and tc light on..

[Steveyn1]

hi all this is baffling me, been looking all over the net and still non the wiser atm.. bought the vxr as a non runner put new engine in the car and it runs sweet as a nut but ive got traction control light on and ids the suspension one.. only error codes ive got is

U2105-71 Invalid Data from ECM (Engine Control Module)

U2105-00 CAN-Bus No Communication with ECM (Engine Control Module

the car was remapped 2k before last owner killed the engine hence ive fitted a replacement which starts sweet but want these other lights off so I can MOT the car as it hasn't seen the road in 2 years..

bugging me now just wondered if anyone else has had same issue... if I search that most people get no communication with ecm mine says invailid data from ecm

cheers in advance steve

have got odd wheel on back atm and a snapped rear spring but I cant seem to read the abs ecu wont let me look at it.. very strange cheers steve

Bit of guess - subframe was off and possibly steering gear has been disconected too?
If so recalibrate steering angle sensor, as well you can look at connector at abs pump, early c's has problem at that place also double check ids wiring in case if its jammed split etc somewhere

[Steveyn1]

thanks for reply.. tbh engine was from above and I re calibrated the steering angle sensor too see if it was that , ive cleaned and checked that plug also checked looms in each wire arch and did continuity test to see if all cables was intact there .. cheers steve soo lost :/

Hmm if thats all done than how cim works any faults like not cancelling indicators or anything strange with it?

[Steveyn1]

checked that only had one fault cant remember but I cleared that.. all indicators work and cancel them self everything works as it should bar wipers which I waiting for a new mech/motor to arrive I thought id try that.. next port of call be to try a abs ecu I guess

[domtorredo]

Could be will check wiring later on to see if ids is wired with abs

[domtorredo]

But if you have a chance to try without buying cim try other cim as from memory someone had simillar isue with vxr and replacement cim sorted it

[Steveyn1]

that's a good point, cheers

[domtorredo]

Well yes they are wired together

[Steveyn1]

looks like I gunna have to try a new abs ecu .. next port of call a
