Sensor Verdict: The LCM system generated an alert on the GREEN (Right Turn) circuit for trailer GV2201978 at site IGQ1. Based on the available evidence, the outcome is rated Inconclusive with a confidence of 35%. The ABS diagnostic results showing 0 active and 0 stored codes are unrelated to the lighting circuit fault that triggered this work order. There is no photographic or documented evidence confirming whether the right turn lighting circuit was inspected, tested, or found to be functional, leaving the original LCM alert unresolved.

Photo Evidence: Four photos were submitted with this work order. Photo 1 (TC_07619) shows the trailer's BIT Annual Inspection Certificate and the Great Dane manufacturer placard for trailer GV2201978 — this is useful for asset identification but provides no lighting circuit information. Photo 3 (TC_07618) shows the trailer unit number 'GV2201978' on the rear corner post, again confirming asset identity only. Photos 2 (TC_07620) and 4 (TC_07621) show a diagnostic tool — likely a Phillips TechAssist or compatible ABS tester — displaying 'ABS Detected, 0 Active Codes' and 'ABS Detected, 0 Stored Codes' respectively. Critically, no photos were submitted showing any trailer lights illuminated, no nosebox wiring photo was provided, and no TechAssist 5-circuit lighting verification screenshot with green 'Verified' indicators was included. The photo package is entirely non-compliant with the LCM troubleshooting procedure.

Vendor Compliance: The vendor (TA) did not follow the prescribed LCM troubleshooting procedure. While a diagnostic tool was used, it was applied to the ABS system rather than the lighting circuits. The instructions explicitly required use of the Phillips Connect TechAssist app to verify all 5 lighting circuits, photograph each light illuminated, capture a clear nosebox wiring photo, and provide a completion screenshot showing green 'Verified' status for each circuit. None of these steps were documented. The vendor notes are described as 'split' with no usable content, and no line items were recorded. The visit appears to have been limited to an ABS check, which does not address the lighting fault alert.

Repair Summary: No repairs were made to the trailer during this work order visit. There are no parts or labor line items, no documentation of any lighting component being inspected or replaced, and no evidence the GREEN (Right Turn) circuit was touched. The ABS scan results, while clean, are irrelevant to the faulted circuit. The alerting circuit was not repaired and was not confirmed as defect-free through the required PCT verification process.

Key Concerns: There are several significant concerns with this work order. First, the vendor appears to have performed an ABS diagnostic instead of — or without also performing — the required lighting circuit inspection, suggesting a possible misunderstanding of the work order scope or a shortcut taken on-site. Second, the complete absence of lighting photos and a TechAssist verification screenshot means this WO cannot be closed as 'no defect found (confirmed with PCT)' — the only available subcategory that would satisfy a clear outcome. Third, the work order completion date (2026-03-31) precedes the photo timestamps (2026-04-02), which is a data integrity discrepancy worth flagging. This work order should be escalated for vendor follow-up to complete the proper LCM lighting inspection and provide the required documentation.
