No Fault Found

Sensor Verdict: The LCM system generated a 'Defect Detected' alert on the GREEN (Right Turn) circuit for trailer GV2501556 at site MDW2. Due to the complete absence of any hands-on inspection or diagnostic data, the sensor result must be classified as Inconclusive with low confidence (30%). There is no technician-gathered evidence to either confirm or refute the original alert. The underlying fault condition on the right turn circuit remains unknown and unresolved.

Photo Evidence: No photos were provided with this work order. The LCM troubleshooting procedure explicitly requires photos of each illuminated light circuit, a clear image of the nosebox wiring, and a TechAssist app completion screenshot showing a green 'Verified' status beside all five circuits. None of these documentation requirements were met. Without visual evidence, it is impossible to assess the physical condition of the right turn circuit, connectors, wiring, or nosebox.

Vendor Compliance: The vendor (TA) did not comply with the LCM troubleshooting procedure in any meaningful way. Two separate dry run events were logged — once by technician 'AB' and once by technician 'JT' — both citing the trailer's position at dock door DD127 as the reason for inability to work. The TechAssist (PCT) app was not used, no circuit verification was performed, and none of the required feedback categories from the troubleshooting procedure were addressed. The work order notes reference an 'override for LCM pilot,' which suggests the alert may have been administratively closed rather than resolved through proper diagnostic work. The site operations team was notified to relocate the trailer to a parking slip (PS912), but it appears the repairs were never rescheduled or completed before WO closure.

Repair Summary: No repairs were made on this work order. The only line items billed were a nominal shop supply/environmental fee ($2.36) and 0.5 hours of lot service labor ($75.00), consistent with a dry run administrative charge. No parts were replaced, no circuit was addressed, and the alerting GREEN (Right Turn) circuit was not repaired or even inspected. There is nothing to assess regarding compliant brand usage.

Key Concerns: Several significant concerns are flagged with this work order. First, the WO was closed despite zero diagnostic or repair activity on the faulted circuit — the 'override for LCM pilot' note suggests manual administrative closure, which bypasses the integrity of the LCM alerting process. Second, two separate technician dry runs were required, indicating a site coordination failure in ensuring the trailer was available and accessible before vendor dispatch. Third, the trailer was reportedly loaded and active at a dock door, which raises the question of whether operations was aware the trailer had an open lighting fault while in service. Finally, no follow-up WO or rescheduled repair is documented, meaning the GREEN circuit fault may still be active on this asset. This WO should be flagged for re-dispatch with a firm requirement that the trailer be staged in a parking slip prior to vendor arrival, and a full PCT-guided inspection must be completed before closure.
