Sensor Verdict: The LCM sensor issued an alert on the YELLOW (Left Turn) circuit of trailer V570293 at site DET3. Based on the available evidence, the sensor result is rated Inconclusive with only 30% confidence. There is no corroborating photo documentation of a lighting defect nor any PCT app verification to confirm or deny the alert. The vendor's brief note claiming lights were verified is insufficient to resolve the sensor's finding in either direction.

Photo Evidence: The single photo submitted (TIRES.jpeg) shows a gloved hand holding what appears to be a tire pressure gauge inserted near the sidewall/bead area of a commercial truck tire. This image has absolutely no relevance to a trailer lighting circuit inspection. There are no photos of any illuminated lights, no photo of the trailer nosebox or wiring, no image of the Left Turn circuit lamp(s), and critically, no screenshot of the Phillips Connect TechAssist (PCT) app showing circuit verification status. The photo documentation requirement for this work order has not been met in any capacity.

Vendor Compliance: The vendor (TA) was explicitly instructed to use the Phillips Connect TechAssist app, photograph each light illuminated, provide a clear nosebox wiring photo, and submit a TechAssist app completion screenshot showing a green 'Verified' status beside each of the 5 circuits. None of these requirements were fulfilled. The technician note — 'TY TA HOOKED UP ALL LIGHTS WORK VERIFED ON APP THANK YOU' — is vague, lacks specificity, and does not reference any of the required feedback categories from the LCM troubleshooting procedure. Vendor compliance is rated as non-compliant.

Repair Summary: No line items were billed, meaning no parts were charged and no labor breakdown was provided. While the vendor claims lights were 'hooked up,' this cannot be validated. It is unclear whether any physical repair was made to the YELLOW Left Turn circuit or any other circuit. The absence of parts charges could suggest a reconnection or minor fix was performed, but without documentation, this remains speculative. The alerting circuit cannot be confirmed as repaired.

Key Concerns: There are multiple serious concerns with this work order. First, the submitted photo is entirely unrelated to trailer lighting — submitting a tire photo for a lighting WO suggests either a documentation error (wrong photo attached) or a lack of diligence by the technician. Second, no PCT app screenshot was provided despite explicit instructions. Third, there are no line items whatsoever, making it impossible to assess what, if anything, was actually done. This WO should be flagged for vendor follow-up, requiring proper photo documentation and a PCT app verification screenshot before the work order is accepted as complete. The possibility of a repeat alert on this circuit is elevated given the lack of confirmed repair.
