The reported complaint of the autopulse platform (b)(6) displayed a fault code 16 (timeout moving to take-up position) error message was confirmed during functional testing and archive data review.The probable root cause of the error message was due to the brake plug not making good contact and being loose.Visual inspection of the returned platform was performed, and no physical damage was observed.The archive data indicated several fault code 16 around the reported event date, confirming the customer's complaint.In addition, unrelated to the reported complaint, the archive showed the presence of the user advisory (ua)23 (compression will exceed 3 revolutions) error message.The autopulse platform failed functional testing due to fault code 16 displayed shortly after starting compression, confirming the customer's complaint.Tightening the plug and securing the connection were performed to address the issue.The (ua)23 error observed in the archive was not reproduced during the functional testing, however, the observed loose brake plug was likely the root cause of the (ua)23 error.Also, unrelated to the reported complaint, it was noted that the drivetrain motor brake gap was too wide, and out of specification.The brake gap was adjusted within the specification to resolve the issue.Following service, the autopulse platform passed the run-in test using the 95% patient large resuscitation test fixture (lrtf) with good known test batteries without any fault or error.The autopulse platform passed the final testing without any fault or error.Historical complaints were reviewed for service information related to the reported complaint, and no similar complaint was reported for the autopulse platform with (b)(6).
