Sensor Verdict: The LCM sensor flagged the BLACK circuit (Clearance / License Plate) on trailer HV2202071 as a potential defect. Based on the available work order data, this alert must be classified as Inconclusive with a confidence of only 35%. The low confidence reflects the complete absence of any physical inspection — the technician never accessed the trailer to validate or refute the sensor's finding. There is no evidence to either confirm a real lighting defect or clear the alert as a false positive.

Photo Evidence: No photos were provided with this work order. The LCM troubleshooting procedure explicitly requires photos of each illuminated light circuit, a clear image of the nosebox wiring, and a TechAssist app screenshot showing a green 'Verified' status beside each of the 5 circuits. None of these documentation requirements were met. The absence of photos is a direct result of the dry run outcome — the technician was unable to reach the trailer — but it nonetheless means the work order is entirely without photographic evidence.

Vendor Compliance: Vendor compliance with the LCM troubleshooting procedure is rated as non-compliant. The technician did not use the Phillips Connect TechAssist (PCT) app, did not inspect any lighting circuits, did not photograph any lights or the nosebox, and did not provide feedback from any of the required expected feedback categories. The notes indicate the technician searched the yard, found the trailer on dock door DD084, and was unable to work on the unit. While the trailer's inaccessibility is a legitimate field constraint, the work order was closed without any rescheduling action, escalation, or follow-up plan documented, which is a process gap.

Repair Summary: No repairs were made on this work order. The only line items billed were a shop supply/environmental fee ($2.36) and 0.5 hours of lot service hourly labor ($75.00) classified as indirect charges — consistent with a dry run. The alerting BLACK circuit was not addressed, inspected, or cleared. The 'pv / Verified only, dryrun' notation at the close of the notes suggests the work order was verified as a dry run completion, not as a lighting circuit resolution.

Key Concerns: Several concerns are flagged for this work order. First, the trailer location discrepancy (expected at PS487, found at DD084) caused the entire visit to be unproductive, and there is no indication that a follow-up work order was created to ensure the LCM alert is eventually investigated. Second, the work order was closed with the notation 'Verified only, dryrun,' which may obscure the fact that the underlying LCM alert on the BLACK circuit remains unresolved. Third, billing 5 hours for a dry run (as mentioned in the technician notes) while only 0.5 hours appear on the line items creates a documentation inconsistency that warrants review. Fleet maintenance reviewers should ensure this trailer is re-queued for a proper LCM inspection before the alert is dismissed.
