Sensor Verdict: The LCM system generated an alert on the GREEN circuit (Right Turn) for trailer V567798. Based on the available evidence, the sensor result is rated as Inconclusive with a confidence of 35%. The technician's notes suggest the lights were operational at time of inspection and that the fault may have been tractor-related; however, without PCT TechAssist app verification, the sensor alert cannot be authoritatively cleared. The possibility remains that an intermittent or wiring-related fault existed and was either self-resolved or misattributed.

Photo Evidence: The only photo provided (MUDFLAPS.jpeg) shows a worn, corroded mudflap bracket and mudflap assembly beneath the trailer. While the mudflap condition reflects general trailer neglect, this photo is entirely irrelevant to the GREEN (Right Turn) lighting circuit fault. No photos of illuminated lights, the nosebox wiring, connector condition, or TechAssist app screenshots were provided. This is a significant documentation gap and constitutes a failure to meet the minimum photographic requirements outlined in the LCM troubleshooting procedure.

Vendor Compliance: The vendor (TA) did not comply with the LCM troubleshooting procedure. The technician explicitly noted they were unable to access or successfully use the Phillips Connect TechAssist (PCT) app to locate and verify the trailer. No TechAssist verification screenshot showing green 'Verified' status across all 5 circuits was provided. The required photos — each light illuminated and a clear nosebox wiring photo — were not submitted. The technician's feedback does not align with the defined expected feedback categories in any documented or verifiable way.

Repair Summary: No repairs were made on this work order. No parts or labor line items were submitted. The technician concluded the issue was tractor-related and noted the trailer lights appeared operational during their visual check. The alerting circuit (GREEN / Right Turn) was not specifically tested, documented, or verified as repaired or fault-free through any approved diagnostic method.

Key Concerns: There are multiple red flags with this work order. First, the only photo submitted is of a mudflap — completely unrelated to a lighting circuit fault — suggesting either negligent documentation or a filing error. Second, the PCT app was not successfully used, which is the cornerstone of the LCM troubleshooting workflow; without it, no circuit-level verification was performed. Third, attributing the fault to the tractor without documented evidence or PCT confirmation is not an acceptable resolution for an LCM-generated trailer alert. This work order should be flagged for non-compliance, and the trailer should be re-inspected with proper PCT TechAssist verification completed and documented.
