have a car that is shutting down every couple weeks, quantum 10k drive, mechanic indicates that it is getting a 1871 rope tension fault, rope 6, and a 709 phase loss fault. those are the only 2 faults, he does a tfr command and car runs fine. there is a ims on job with rope monitor program in ims, and all the rope tensions are within 5-10 percent of each other, they actually look closer then the other cars. after researching i see in the manual that 1871 is just a warning, and should not shut the car down. also 709 fault indicates if it clears, it should return to service. has anyone had any experience with either of these faults requiring a TFR to get car running. as far as i can see, neither should require a tfr reset what do you think
