No Fault Found

Sensor Verdict: The LCM system generated an alert on the BLACK circuit, which monitors Clearance and License Plate lights. The sensor result is classified as Inconclusive with 35% confidence, as the vendor's claim of no defect is unsupported by any verifiable documentation. The LCM sensor may have detected a real intermittent or transient fault on the clearance/license plate circuit, but the lack of proper follow-through by the vendor makes it impossible to confirm or deny the alert with confidence.

Photo Evidence: The single photo submitted — MUDFLAPS.jpeg — depicts the underside of the trailer near the rear axle and mudflap area. This image is completely irrelevant to the faulted BLACK circuit (Clearance/License Plate lights). There are no photos of illuminated clearance lights, license plate lights, or any other lamp circuit. There is no nosebox photo, no wiring inspection photo, and critically, no TechAssist (PCT) app screenshot showing green 'Verified' status for any of the five circuits. The photo documentation is wholly non-compliant with the LCM troubleshooting procedure.

Vendor Compliance: The vendor (TA) did not follow the prescribed LCM troubleshooting procedure. The technician notes state 'verified in app,' but no screenshot or digital proof of PCT app usage was provided. The required TechAssist app completion screenshot — showing green 'Verified' beside each of the five circuits — is absent. The vendor did not photograph each illuminated light, did not provide a nosebox wiring photo, and did not categorize the outcome using the defined feedback categories. Overall vendor compliance with the troubleshooting protocol is rated as very poor.

Repair Summary: No repairs were made, no parts were listed, and no labor was billed. While a 'no defect found' outcome is a valid resolution if properly confirmed via PCT, the vendor failed to provide the required confirmation. The alerting BLACK circuit (Clearance/License Plate) was not demonstrably inspected or cleared through any documented process. Without line items or compliant documentation, there is no evidence that any meaningful inspection of the lighting system occurred.

Key Concerns: There are several significant concerns with this work order. First, the only photo submitted is of the trailer's mudflap/axle area, which has no bearing on the faulted circuit — this raises questions about whether any actual lighting inspection took place. Second, the vendor's reference to 'verified in app' without providing a screenshot is insufficient and does not meet the documented standard. Third, the BLACK circuit alert remains unresolved from a documentation standpoint and may represent a real defect that was overlooked or dismissed. This work order should be flagged for vendor accountability review, and the trailer (WV2500162) may warrant a re-inspection at its next available opportunity to confirm the clearance/license plate circuit integrity.
