Lighting - Failed Light

Sensor Verdict: The LCM sensor flagged the RED (Brake) circuit, and the technician's notes confirm the existence of a shorted light — specifically described as a strobe light that is 'out due to a shorted light.' This corroborates the sensor alert with moderate-to-high confidence (82%). The defect is real and documented verbally, though the lack of proper photographic evidence and TechAssist app confirmation introduces some uncertainty regarding exact circuit location and full circuit scope.

Photo Evidence: All five submitted photos show a gloved technician using a tread depth gauge on commercial trailer tires, documenting tread wear conditions on what appears to be a dual-tire axle configuration. Photos 2 and 3 notably show a tire sidewall separation/delamination defect visible near the shoulder of the tire — a significant tire safety concern in its own right. However, none of the five photos depict any lighting components, the nosebox, wiring harnesses, or any light fixture in an illuminated or defective state. There are no TechAssist app screenshots provided. The photo documentation is wholly non-compliant with the LCM troubleshooting procedure requirements.

Vendor Compliance: The vendor did not follow the prescribed LCM troubleshooting procedure. The Phillips Connect TechAssist (PCT) app was not used, no screenshots showing green 'Verified' status across the five circuits were provided, and no photos of any illuminated lights or nosebox wiring were submitted. The technician's notes reference a 'LCM Phillips Light Campaign' and a 'routine inspection,' but the depth of diagnostics is limited to identifying a single shorted light without locating or testing the full circuit. The failure subcategory of 'light failure' appears appropriate based on the tech notes, but cannot be fully confirmed without proper app-based verification.

Repair Summary: No repairs were made at the time of WO closure. The technician identified the defective light (described as a strobe light on the brake circuit) but noted the part was on backorder and the stock order had not yet arrived. The WO was closed with the defect unresolved and the alerting RED circuit still in a faulted state. No parts were listed under line items, and no labor charges reflect any corrective action taken. This is a significant concern as the trailer was presumably returned to service with a known lighting defect.

Key Concerns: Several major flags are present in this work order. First, the WO was closed without completing the repair — the trailer has an unresolved brake light circuit fault and should not be operating without follow-up. Second, the submitted photos are completely mismatched to the work order category (WHEELS_AND_RIMS photos submitted for a lighting work order), suggesting possible administrative error or photos submitted to the wrong WO. Third, Photos 2 and 3 reveal what appears to be a tire sidewall separation, which is a separate but critical safety defect that should be escalated immediately regardless of this WO's scope. Fourth, the PCT app was not used and no verified circuit confirmation exists. A follow-up WO should be generated to confirm part receipt, complete the brake light repair, and provide proper LCM documentation including TechAssist verification.
