No Fault Found

Sensor Verdict: The LCM system generated an alert on the BLACK circuit, which governs Clearance and License Plate lighting on trailer WV2500994. Based on the available evidence, the sensor result is classified as Inconclusive with a confidence of 35%. The technician's notes indicate no visible lighting defects were found, but critically, the ATIS lamp sensor was reported as not connected. A disconnected ATIS sensor is itself a hardware anomaly that could have generated or masked the original circuit fault, meaning the sensor alert cannot be fully validated or dismissed without a properly connected sensor and a completed TechAssist verification cycle.

Photo Evidence: Two photos were submitted with this work order. Photo 1 shows the front nosebox area of the trailer, with the Phillips Connect LCM unit visible and a green indicator light illuminated on the 7-way connector — suggesting basic electrical connectivity. However, this photo does not constitute proper nosebox documentation as it does not show the internal wiring, connector seating, or LCM insert status clearly. Photo 2 shows the rear of the trailer with the license plate (Indiana plate PE26223) and what appears to be functioning red tail/brake LEDs illuminated above it. No photos were provided showing the clearance lights individually illuminated, no TechAssist app screenshot showing all 5 circuits verified green was submitted, and no close-up of the license plate light itself was included. The photo documentation is substantially incomplete relative to the required procedure.

Vendor Compliance: The vendor (TA) partially followed the LCM troubleshooting procedure. They did connect to the unit using the Phillips Connect TechAssist app, which is a positive step. However, compliance breaks down significantly from there. The technician did not photograph each light in the circuit individually while illuminated, did not provide a clear nosebox wiring photo showing internal connector condition, and critically did not provide a TechAssist app completion screenshot showing green 'Verified' status beside all 5 circuits. The vendor notes are also poorly written and difficult to parse, reducing confidence in the diagnosis. The finding that the 'ATIS lamp sensor is not connected' is significant but was not acted upon or escalated. This finding alone should have prompted further investigation or a follow-up action item.

Repair Summary: No repairs were made on this work order. There are no line items for parts or labor beyond what appears to be a diagnostic visit. The alerting BLACK circuit (Clearance/License Plate) was not repaired, replaced, or confirmed as fully operational via the required TechAssist verification. The disconnected ATIS lamp sensor — which is a component of the Smart 7 / LCM system — was identified but not reconnected or documented as corrected. This is a missed opportunity to resolve what may be the root cause of the original LCM alert.

Key Concerns: Several concerns are flagged for this work order. First, the disconnected ATIS lamp sensor is a direct Smart 7 system issue that was identified but not resolved, and it may be the proximate cause of the BLACK circuit alert. Second, the absence of a TechAssist 'Verified' screenshot means there is no objective confirmation that all 5 circuits are healthy. Third, photo documentation is insufficient — no individual clearance light or license plate light photos were submitted. Fourth, the technician notes contain numerous spelling errors and vague language, raising concerns about the quality and thoroughness of the inspection. This work order should be flagged for vendor follow-up to reconnect the ATIS sensor, complete a full TechAssist verification, and resubmit with compliant photo documentation before the WO is closed as resolved.
