No Fault Found

Sensor Verdict: The LCM system generated an alert on the GREEN (Right Turn) circuit of trailer V570846, indicating a potential fault in the right rear turn signal circuit. The sensor result is rated as Inconclusive with 35% confidence. The vendor's claim of 'no issues' cannot be validated because no supporting documentation was provided — no TechAssist/PCT app screenshot, no illuminated light photos, and no nosebox wiring image. The alert may represent a real intermittent fault or a transient condition, but without proper verification, neither outcome can be confirmed.

Photo Evidence: The seven photos submitted with this work order are entirely unrelated to the lighting system or the faulted GREEN circuit. Photos 1 and 6 show a trailer tire with what appears to be a screw or nail puncture embedded in the tread — a tire defect, not a lighting issue. Photo 4 shows a flat/deflated trailer tire on the rim. Photo 2 shows the Hyundai Translead VIN/spec plate for V570846, confirming asset identity. Photo 3 shows the trailer unit number V570846 on the rear corner post. Photo 5 shows the rear doors of an Amazon trailer (different asset, Amazon-branded dark trailer, license PF79217). Photo 7 shows an Indiana license plate PF79217. Notably absent are: any photos of the right turn light illuminated, any photos of other circuits illuminated, any nosebox wiring photo, and any Phillips Connect TechAssist app screenshot showing circuit verification. The photos submitted appear to document tire issues unrelated to this LCM work order and may have been attached in error or belong to a separate work order.

Vendor Compliance: The vendor (TA) did not comply with the LCM troubleshooting procedure. The procedure explicitly requires: use of the Phillips Connect TechAssist app, photos of each light illuminated, a clear photo of the nosebox wiring, and a TechAssist app completion screenshot showing a green 'Verified' status beside each of the 5 circuits. None of these requirements were met. The technician note 'verified in app' is vague and unsupported — no screenshot was included. Furthermore, the vendor submitted zero lighting-related photos, and zero line items were billed, suggesting minimal engagement with the actual lighting system inspection.

Repair Summary: No repairs were made and no parts were billed. The vendor categorized this as a no-fault finding, but the resolution does not meet the threshold for 'no defect found (confirmed with PCT)' since no PCT/TechAssist confirmation screenshot was provided. The faulted GREEN (Right Turn) circuit was not demonstrably addressed or cleared through proper protocol. This work order cannot be considered closed in good standing from a documentation and compliance standpoint.

Key Concerns: There are several significant concerns with this work order. First, the photos submitted appear to be from a completely different inspection — they document tire damage (nail puncture, flat tire) rather than lighting system components, raising questions about whether photos were attached to the wrong work order. Second, the vendor's note is insufficient — 'no issues with lights verified in app' does not meet the specificity requirements of the troubleshooting procedure and does not reference the expected feedback categories. Third, no line items were submitted, which combined with the lack of documentation suggests this inspection may not have been thoroughly performed. Fleet maintenance reviewers should consider flagging this vendor response as non-compliant and requesting a re-inspection with full TechAssist documentation, or escalating to ensure the GREEN circuit is genuinely fault-free before returning the asset to service.
