No Fault Found

Sensor Verdict: The LCM system flagged the RED (Brake) circuit on trailer HV2502620, suggesting a potential brake light defect. Confidence in the sensor result is low (35%) due to the complete absence of diagnostic documentation. The vendor did not confirm, deny, or specifically address the alerting circuit in their notes, making it impossible to validate whether the sensor detected a real fault. The generic 'light campaign' language provides no circuit-specific insight.

Photo Evidence: Fourteen defect photos were submitted along with a manufacturer data plate photo. The photos show various angles of the trailer's exterior lighting, rear lamp clusters (Photos 9, 11, 13, 14), interior trailer views (Photos 4, 8, 10), the trailer top rail and side panels (Photos 1, 2, 5, 12), the front corner of the trailer (Photos 3, 6), a license plate area (Photo 7), and a Hyundai Translead manufacturer data plate (Photo 15). In Photos 9 and 11, the rear tail/brake lights appear to be illuminated and functional (red LEDs lit). However, no TechAssist app screenshot showing green 'Verified' status across all five circuits was provided. There is no clear nosebox wiring photo present in the submission. Photos of individual light circuits systematically illuminated per the PCT app procedure are absent. The photos provided appear to be general condition documentation rather than targeted diagnostic evidence.

Vendor Compliance: The vendor did not comply with the LCM troubleshooting procedure. The required steps — using the Phillips Connect TechAssist app, photographing each light circuit illuminated, capturing a clear nosebox wiring photo, and providing a TechAssist completion screenshot showing green 'Verified' beside each of the five circuits — were not completed. The vendor notes simply state 'PERFORMED LIGHT CAMPAIGN,' which is a non-specific, catch-all descriptor that does not map to any of the required feedback categories. There is no documentation of which specific lights were inspected, tested, or corrected, and no feedback category from the defined list was applied.

Repair Summary: No line items — neither parts nor labor specific to the RED (Brake) circuit — were submitted. The work order lists no components replaced and no specific corrective action documented. The 'light campaign' notation typically implies a general inspection or minor adjustment pass, but without itemized documentation it cannot be confirmed that any repair was made to the alerting circuit. The brake lights visible in Photos 9, 11, and 13 appear to be functioning LED units, but this cannot be attributed to any documented repair action.

Key Concerns: Several significant concerns exist with this work order. First, the vendor failed entirely to use the Phillips Connect TechAssist (PCT) app, which is the core diagnostic requirement for LCM-triggered work orders. Second, no nosebox photo was provided, which is a mandatory documentation requirement. Third, the vague 'light campaign' complaint/cause/correction language suggests the vendor may have treated this as a routine PM rather than an LCM-specific diagnostic event. Fourth, the trailer is a 2024 Hyundai Translead (manufactured 03/24), making it a relatively new asset — the recurrence of an LCM alert on a near-new trailer warrants attention. Fifth, with no line items submitted, there is no financial accountability for the repair visit. This work order should be returned to the vendor for proper PCT app documentation and circuit-specific verification before it can be accepted as a valid LCM resolution.
