Since having my 850 dyno tested, the ABS and traction control do not function, the test lights go out after start-up but if i switch on the tracs switch it does not light up. Fault code read-out gave 141, 142, 213, 214, for some reason i could not clear the fault codes. I followed the prescribed process, i.e. go through all the codes plus the 1st code again, hold button down for 5 secs resulting in light staying lit for approx 3 secs, then i held the button down a further 5 seconds plus. Then checked the codes again hoping for 1-1-1, but they had not cleared. is there something i am not doing correctly?, anybody got any ideas why these faults occurred- is it because of the dyno testing with front wheels only turning?.
