Lighting - Missing Light

Sensor Verdict: The LCM issued an alert on the RED (Brake) circuit for trailer WV2502072 at site RFD3. Based on the available work order data, the sensor result is rated Inconclusive with a confidence level of 35%. There is no evidence of a confirmed lighting defect, nor is there sufficient verified documentation to rule one out. The technician's claim that all lights are functional is unsubstantiated by any app-based verification or photographic proof, leaving the original LCM alert unresolved.

Photo Evidence: No photos were attached to or referenced in this work order. The LCM troubleshooting procedure explicitly requires photos of each light illuminated and a clear picture of the nosebox wiring, as well as a TechAssist app screenshot showing green 'Verified' status beside each of the 5 circuits. None of these were provided. The complete absence of photo documentation is a significant compliance gap and makes it impossible to assess the physical condition of the brake lights, wiring, or nosebox for trailer WV2502072.

Vendor Compliance: The vendor (TA) did not follow the prescribed LCM troubleshooting procedure. The technician referenced using 'Help Assist' to verify lighting functionality, but this does not align with the required use of the Phillips Connect TechAssist (PCT) app. No PCT app completion screenshot was provided, no green 'Verified' confirmation was documented for any of the 5 circuits, and no structured feedback from the required defect category list was submitted. The notes are informal and lack the specificity required by the LCM troubleshooting protocol. This work order fails to meet the minimum documentation standards for an LCM-generated alert.

Repair Summary: No lighting repairs were made. The line items on this work order are entirely unrelated to the faulted RED brake circuit — they consist of a tire pressure sensor activation (AMAZON PCT SENSOR ACTIVATION), standard service labor, a shop supply fee, and lot service hourly labor. None of these items address lighting, wiring, connectors, or the nosebox. The alerting circuit (RED/Brake) was not repaired or confirmed as defect-free through any verifiable process. The cost incurred appears to reflect a tire-related service, not a lighting inspection.

Key Concerns: There are multiple significant concerns with this work order. First, the line items are entirely mismatched to the LCM alert — tire sensor work was billed on a lighting fault work order, raising questions about whether the correct trailer and complaint were addressed. Second, there is a complete absence of photographic evidence and PCT app documentation, both of which are mandatory per the troubleshooting procedure. Third, the technician's language ('COMPLETE J F TA COMPLAINT LCMPILOT') suggests this may have been treated as a routine check-off rather than a structured LCM investigation. Fourth, the 'pv' note at the end is unexplained. Collectively, these issues indicate a vendor shortcut that leaves the original LCM alert unresolved and the trailer's brake circuit status unverified. This work order should be flagged for vendor feedback and potentially re-opened for proper LCM inspection.
