Sensor Verdict: The LCM sensor issued an alert on the BLACK circuit, which governs Clearance and License Plate lighting on trailer WV2500382. Based on the vendor's notes and the absence of any documented repair or PCT verification screenshot, the sensor result is rated as Inconclusive with a confidence of 35%. The technician states no issue was found with the lights, but the lack of a TechAssist 'Verified' confirmation and the discovery of disconnected ATIS/cargo sensors from the Smart Seven leaves the root cause of the original alert ambiguous and unresolved.

Photo Evidence: The eight photos provided show the rear of the trailer (Amazon-branded, AZNG WV2500382), dual rear tires on what appear to be drive axles showing moderate-to-significant wear, mud flaps (one of which appears to be resting flat on the ground rather than hanging properly), and a side view of the trailer. Critically, there are no photos of the BLACK circuit lights illuminated, no nosebox wiring photos, and no TechAssist app screenshot showing green 'Verified' status beside each of the 5 circuits. The photos submitted do not satisfy the LCM troubleshooting photo requirements and appear to be general condition photos rather than targeted lighting documentation. The tire wear observed in Photos 2 and 7 and the dislodged mud flap in Photo 5 are notable separate maintenance concerns but are outside the scope of this LCM work order.

Vendor Compliance: The vendor did use the Phillips Connect app, which is a positive step toward compliance. However, they did not fulfill the full troubleshooting procedure as outlined in the LCM instructions. There is no TechAssist completion screenshot showing green 'Verified' status for each of the 5 circuits, no photos of each light in the BLACK circuit illuminated, and no clear nosebox wiring photo. The technician's notes are brief and lack structured feedback aligned with the required category list (e.g., 'no defect found (confirmed with PCT)' vs. the actual outcome here which is 'no defect found (not confirmed with PCT)'). Vendor compliance with the prescribed procedure is rated as insufficient.

Repair Summary: No repairs were made on this work order. There are no line items for parts or labor, and the technician's notes confirm that no defects were corrected. The alerting BLACK circuit was not confirmed as repaired or cleared. The only notable finding was that the ATIS lamp and cargo area sensors are not connected to the Smart Seven nosebox — this is a system configuration gap that could itself be contributing to erroneous LCM alerts and should be addressed, but no corrective action was documented or performed during this visit.

Key Concerns: Several concerns are flagged for this work order: (1) The ATIS lamp and cargo sensors are disconnected from the Smart Seven — this is a meaningful finding that may be causing or contributing to the LCM alert, yet no repair was made and no follow-up was scheduled; (2) No PCT verification screenshot was submitted, meaning the BLACK circuit cannot be considered cleared; (3) The photo set submitted is entirely non-compliant with LCM photo requirements — none of the eight photos show illuminated lights or the nosebox; (4) Tire wear and a displaced mud flap are visible in the photos and represent separate safety concerns that should be escalated independently; (5) No labor or parts line items were submitted, raising questions about whether the diagnostic work was properly billed or if the visit was sufficiently thorough. This work order should be flagged for vendor follow-up to properly close the LCM alert with documented PCT verification.
