Sensor Verdict: The LCM system generated an alert on the BLACK circuit, which governs Clearance and License Plate lighting on trailer HV2307031. Given the absence of any specific repair documentation, TechAssist verification, or confirmed fault finding, the sensor result is rated as Inconclusive with a confidence of 30%. There is insufficient evidence to confirm whether the sensor correctly identified a real defect or triggered a false positive, as the vendor did not perform nor document the required diagnostic steps to validate or refute the alert.
Photo Evidence: Three photos were submitted under the LIGHTS.jpeg label. Photo 1 shows the interior of the trailer from the rear looking forward, photographed at night — the interior is largely dark with no lights visibly illuminated for inspection purposes, and this does not serve as evidence of a functioning clearance or license plate circuit. Photo 2 shows a green clearance/marker lamp illuminated, which suggests at least one lamp in a related circuit is functional, but no context is given for which specific circuit or position this lamp belongs to, and no TechAssist app screenshot accompanies it. Photo 3 shows the exterior rear corner of the trailer with the unit number HV2307031 visible, taken at night — this is an asset identification photo and not a diagnostic or repair confirmation photo. Critically, there are no photos of the nosebox wiring, no TechAssist app completion screenshot showing green 'Verified' status on all five circuits, and no comprehensive illuminated photos of each light in the faulted BLACK circuit. The photo documentation is substantially non-compliant with the required troubleshooting procedure.
Vendor Compliance: The vendor (COX) did not comply with the LCM troubleshooting procedure. The procedure explicitly requires use of the Phillips Connect TechAssist (PCT) app, photos of each light illuminated, a clear nosebox wiring photo, and a TechAssist completion screenshot showing green 'Verified' status beside each of the five circuits. None of these requirements were met. The vendor notes consist solely of 'PERFORMED LIGHT CAMPAIGN,' which is a blanket maintenance action with no diagnostic specificity. The failure category cannot be reliably assigned from the defined list because no actual diagnostic feedback was provided. The PCT app was not used, and no verified confirmation of circuit health was documented.
Repair Summary: No line items were submitted for this work order, meaning no parts were replaced and no specific labor task beyond a generic 'Light Campaign' was recorded. There is no evidence that the BLACK (Clearance/License Plate) circuit was inspected, tested, repaired, or confirmed functional. Without line items or TechAssist verification, it is impossible to determine whether any corrective action was taken on the alerting circuit. The work order appears to have been closed without substantive repair or diagnostic work specific to the LCM alert.
Key Concerns: Several significant concerns exist with this work order. First, the vendor response is entirely generic — 'Light Campaign' is not an acceptable diagnostic or repair notation for an LCM-triggered work order. Second, the complete absence of line items raises questions about whether any work was actually performed. Third, the photos submitted are insufficient and non-compliant — no nosebox photo, no TechAssist screenshot, and no clear illuminated photo of each light in the faulted circuit. Fourth, the faulted BLACK circuit is never specifically mentioned in the vendor notes, raising the possibility that the alerting circuit was never addressed. This work order should be flagged for vendor follow-up, requiring resubmission with proper TechAssist documentation, circuit-specific photos, and a detailed account of findings and repairs made on the BLACK circuit.
