Sensor Verdict: The LCM system generated a 'Defect Detected' alert on the RED (Brake) circuit for trailer V565833 at site DET3. Confidence in the sensor result is rated low-to-moderate (35%) because the vendor asserted no defect exists but failed to provide any verified photographic or app-based evidence to support that claim. The absence of proper documentation leaves the original sensor alert unresolved and neither confirmed nor credibly refuted.

Photo Evidence: Two photos were submitted with this work order, both labeled 'TIRES.jpeg.' The first image shows two trailer tires/wheels leaning against a concrete barrier wall beside a parked trailer. The second image shows a close-up of a heavily corroded and rusted steel wheel hub with visible surface rust throughout the rim face and hub mounting area. Neither photo is relevant to the faulted RED (Brake) lighting circuit. There are no photos of brake lights illuminated, no rear lamp cluster images, no nosebox wiring photos, and no TechAssist app verification screenshot. The photo submission is entirely non-compliant with the LCM troubleshooting procedure.

Vendor Compliance: The vendor (TA) did not follow the prescribed LCM troubleshooting procedure in any meaningful way. The technician note reads simply 'TA LIGHTS WORK NO ISSUE THANK YOU QE,' which provides no specifics about what was inspected, how the brake circuit was tested, or what steps were taken. The required Phillips Connect TechAssist (PCT) app was not used, or at minimum, no screenshot demonstrating green 'Verified' status across all 5 circuits was provided. None of the expected feedback categories from the defined list were formally cited. This represents a significant compliance failure.

Repair Summary: No repairs were made, and no parts or labor line items were submitted. The vendor's position is that no defect exists on the RED (Brake) circuit. While a 'no defect found' outcome is a valid conclusion, it is only acceptable when confirmed via the PCT app with a verified screenshot, which was not provided here. As a result, there is no validated basis for closing this work order as defect-free.

Key Concerns: There are multiple serious concerns with this work order. First, the submitted photos are completely irrelevant to the lighting alert — tire/wheel images suggest either the wrong photos were attached or the technician did not inspect the lighting system at all. Second, no PCT app verification was performed or documented, violating the core requirement of the LCM troubleshooting procedure. Third, the vendor note is dismissive and non-specific, offering no actionable detail. This work order should be flagged for vendor non-compliance, returned for proper re-inspection with PCT app documentation, and the original LCM alert on the RED (Brake) circuit should remain open until verified.
