No Fault Found

Sensor Verdict: The LCM system generated an alert on the GREEN circuit, which corresponds to the right-side turn signal lighting on trailer HV2408155. Based on the available evidence — primarily the PCT TechAssist screenshot showing all circuits verified — this appears to be a 'No Fault Found' outcome. However, confidence is low (35%) because the vendor documentation is incomplete and does not clearly describe a structured inspection of the green circuit specifically. The original alert may have been transient, intermittent, or triggered by a loose connection that self-resolved prior to inspection.

Photo Evidence: Six photos were submitted with this work order. Photo 1 (TC_09163) shows the trailer's VIN/data plate confirming the asset as HV2408155, a Hyundai Translead trailer. Photo 2 (IMG_9356) is the PCT TechAssist screenshot showing all five circuits (Red, Green, Yellow, Brown, and an unlabeled fifth) marked as 'Verified' with 'No data / No defects' noted for each — this is the most critical piece of diagnostic evidence provided. Photos 3 and 4 (TC_09165, TC_09166) show exterior rear and side views of the trailer, with lighting visible but not individually illuminated for circuit-specific verification. Photo 5 (TC_09162) shows the trailer unit number from below. Photo 6 (TC_09164) shows the upper rear corner of the trailer, apparently focused on a clearance or marker light area. Notably absent are: close-up photos of each rear lamp illuminated individually, a clear photo of the nosebox and wiring connections, and any photo specifically showing the green (right turn) lamps energized. The photo set is insufficient for a complete circuit-level verification.

Vendor Compliance: The vendor partially followed the LCM troubleshooting procedure. They did use the Phillips Connect TechAssist app and provided a screenshot showing all circuits verified — which satisfies the core diagnostic requirement. However, they failed on several other required elements: they did not photograph each light illuminated individually, did not provide a clear nosebox wiring photo, and their written notes are vague, misspelled, and lack any specific feedback from the required defect category list. The notes acknowledge slow upload conditions, which may partially explain missing photos, but this does not excuse the documentation shortfall. The technician's feedback does not map to any of the required feedback categories with sufficient specificity.

Repair Summary: No repairs were made on this work order. There are zero line items for parts or labor beyond the apparent inspection visit. The vendor concluded all lights were functional based on the PCT app results. The alerting GREEN circuit was not specifically addressed with any corrective action, nor was any root cause identified for the original LCM alert. While a 'no defect found' outcome is a valid and expected result, it requires confirmation through the PCT app — which was provided — and through physical lamp-illuminated photos — which were not adequately provided.

Key Concerns: Several concerns exist with this work order. First, the absence of individual illuminated lamp photos for the green circuit specifically means there is no visual confirmation that the right turn lights are physically intact and functional. Second, the nosebox was never photographed, leaving open the possibility of a wiring or connection issue that the app may not have fully captured at that moment. Third, the vendor notes are extremely poor in quality — suggesting a rushed or low-effort inspection. Fourth, the original LCM alert on the GREEN circuit remains unexplained; if the fault was intermittent (e.g., a loose connector or corroded pin), it may recur. A follow-up inspection or re-alert monitoring is recommended. No mismatched circuit colors were noted between the alert and the inspection results, which is a minor positive.
