No Fault Found

Sensor Verdict: The LCM alert on the BLACK (Clearance / License Plate) circuit is rated Inconclusive with a confidence of 35%. There is insufficient evidence to confirm that a real lighting defect existed on the BLACK circuit. The vendor performed a general light check and noted the unit was 'ready for service,' which could imply no defect was found — however, this is undermined by the explicit notation of missing app photos and 'Cause TBD.' Without a completed TechAssist verification showing a green 'Verified' status for each circuit, the sensor alert can neither be validated nor dismissed. The WO was flagged internally as a 'PCT TRAINING REQUIRED' event, suggesting the alert may have been partially administrative in nature, but that does not preclude a genuine underlying fault.

Photo Evidence: No compliant lighting photos were provided for this work order. The technician's own notes acknowledge 'missing app photos,' which is a direct failure of the documentation requirement. There are no photos of individual illuminated lights on the BLACK circuit (clearance lamps, license plate lamp), no clear nosebox wiring photo, and no TechAssist app screenshot showing green 'Verified' status for the five circuits. The absence of photo evidence makes it impossible to assess the physical condition of the clearance or license plate lamps, the nosebox connections, or wiring integrity. This is a critical documentation gap.

Vendor Compliance: Vendor compliance with the LCM troubleshooting procedure is poor. While the technician did access the Phillips Connect app and attempted sensor activation, the core requirements were not met: (1) no photos of each light illuminated were provided, (2) no clear nosebox photo was provided, (3) no TechAssist completion screenshot showing green 'Verified' for all five circuits was included, and (4) no specific feedback category from the required list was definitively applied. The door sensor activation was also incomplete because the trailer was sealed. The work was largely characterized as a sensor activation/onboarding exercise (consistent with 'PCT TRAINING REQUIRED' notes), not a focused diagnostic of the BLACK circuit fault. The verifier's note — 'verified only can't confirm if repairs have been completed' — further confirms non-compliance.

Repair Summary: No lighting repairs were made. No parts associated with the BLACK (clearance/license plate) circuit were replaced. The line items reflect PCT sensor activation labor, standard service labor (0.1 hours), lot service hourly labor (0.3 hours), and a shop supply fee — none of which correspond to a lighting repair. The 'AMAZON PCT SENSOR ACTIVATION' line item suggests the visit was centered on initializing or re-activating the Phillips Connect monitoring sensors, not addressing a confirmed lamp failure. Because no lighting parts were replaced, the 'compliant brand' field is not applicable.

Key Concerns: Several significant concerns exist with this work order. First, the WO was effectively treated as a PCT onboarding/training event rather than a legitimate defect repair, which means a potentially real BLACK circuit fault may have been overlooked or deferred. Second, the complete absence of required photos is a major compliance failure and creates zero audit trail for the lighting condition. Third, the door sensor could not be verified due to a sealed trailer — this limits the completeness of any sensor activation performed. Fourth, the verifier explicitly stated they could not confirm whether repairs were completed, which is an unusual and concerning closing remark. Fifth, the multi-technician, multi-note structure of this WO (JT, JG, RLE, pv) suggests handoffs that may have contributed to incomplete follow-through. This WO should be flagged for re-inspection of the BLACK circuit with full TechAssist documentation.
