Visual inspection of the external components revealed split housings and impact shock damage to the front housing.Visual inspection of the internal components revealed signs of impact shock on the main printed circuit board assembly (pcba) and on the housing's bosses and inserts, and a disconnected and skewed j2 ribbon cable.The driver's alarm history was reviewed and revealed a new alarm, a 34 fault code.This fault code alarm is likely the customer-reported alarm as it can occur due to intermittent power communication errors during an impact shock, power cycling of the driver or during onboard battery exchange.The driver passed all sections of functional testing.Additionally, an onboard battery exchange test was also performed utilizing nine functioning freedom onboard batteries.No alarms were produced during this test.During investigation testing, the customer-reported issue was not reproduced and there was no evidence of a device malfunction.The reported fault alarm was most likely caused by impact shock to the driver, temporarily causing an intermittent power connection.This power connection error would cause a permanent fault alarm to occur.This issue will continue to be monitored and trended as part of the customer experience process.Syncardia has completed its evaluation of this complaint and is closing this file.(b)(4) follow-up report 1.
