H4 (device manufacture date) was updated.The customer's reported complaint that the thermogard xp ivtm system (sn (b)(6)) frequently displayed tcmid:02 (ce danfoss error) error messages was confirmed in the system's event log data and during functional testing.The root cause was a degraded cable connection between the danfoss module and pic 16 board due to burnt pins on the connectors, likely due to corrosion and electrical shorting inside the connectors.The thermogard console was manufactured in october 2015 and is over 8 years old, well beyond its expected service life of 5 years.No physical damage was observed on the thermogard console during the visual inspection.Reviewing the system's event log data showed tcmid:02 (ce danfoss error) error messages around the reported event date, confirming the reported complaint.The system failed initial functional testing due to a tcmid:02 error message, confirming the reported complaint.The investigation findings revealed burned pins on the p22 connector of the pic-hsg cable harness and the j22 connector on the cooling engine harness, which connects the danfoss module to the pic 16 board.The assembly wire harness pic 16 was replaced to remedy the issue.The pic16 board and the danfoss module controller were replaced as a precautionary measure to prevent the reoccurrence of a possible connection issue between the two connectors.Following service, the thermogard console passed all tests with no issues, and readings were within the specified limits.Historical complaints were reviewed for service information related to the reported complaint, and there was no previous history of complaints reported for the thermogard console with serial number (b)(6).
