Angry Electronic Parking Brake software fault

Hello there
ive had a look through the previous threads and I cant see anything related to my little problem. I have a 2005 Grand Scenic, and a 'check parking brake' on the dash I have had the brake cables replaced by a company in Dublin that was recommended on another thread, on the Electronic Parking brake due to the outer cable crushing in on itself bring a 'vehicle moves with maximum brake fault' intermittently.

I readjusted the cables and wound them out manually inorder to fit back on to the callipers as the previous position on the left hand threaded bit of the motor mechanism would have been too tight. I have refitted the complete EPB back to the car and it was working perfectly for two days, the 'check parking brake' light was still on, but the parking brake was working. Then I came to put the parking brake on and I got a high pitch warning noise from the dash and the 'stop' & parking brake symbol flash up and get that everytime I start the vehicle. The EPB doesnt actitvate and is un-operational.

I previously worked at Renault for 10 years so I can get access to a clip, so I read the faults and have 3 permament faults in this order are:

DF 043- parking brake motor
DF 046-brake cables/motor link
DF 038- Auto trans multiplexed emission missing

I have had a look at the fault finding documentation and the only thing I can find is that when the emergency parking brake lever is moved (which i did pull trying to refit the level when I reinstalled the unit, and has been reattached) there is an actuator command to release the motor and reclick the cables back together. Everytime I do this the dash screams and the parking brake lights and message comes on.

Has anyone got any ideas on how to tell the computer that it needs to reset the cable lengths, or wipe the computer memory, so it knows where the cables are in relation to the motor. I did reprogamme the computer so i think the bottom fault is due to me not configuring properly.

Thanks for your time, any help or ideas

Re: Electronic Parking Brake software fault

Have you tried disconnecting the battery while doing the mechanicals and cables, then connect back up?
