Lighting - Missing Light

Sensor Verdict: The LCM sensor alert on the RED (Brake) circuit is confirmed as a legitimate defect detection with a confidence level of 85. The vendor's own notes corroborate the alert by stating that a Grote light is missing from the trailer — a direct cause of a brake circuit open/fault condition that the LCM system would reliably flag. There is no contradicting evidence; the alert and the field finding are in agreement.

Photo Evidence: The four attached photos (all labeled BRAKES.jpeg) depict undercarriage views of what appears to be trailer axle, suspension, and brake hardware components — including what look like brake chambers, slack adjusters, axle brackets, and dual tires. These photos are not relevant to a lighting circuit inspection. None of the photos show an illuminated brake light, a missing light housing, a damaged connector, or the nosebox wiring. There are no TechAssist app screenshots demonstrating circuit verification. The photo documentation is entirely non-compliant with the required LCM troubleshooting procedure. It is possible the vendor confused brake hardware documentation with brake light circuit documentation, which is a notable procedural error.

Vendor Compliance: The vendor did not follow the LCM troubleshooting procedure as instructed. The procedure explicitly requires use of the Phillips Connect TechAssist (PCT) app, photographs of each light in the circuit illuminated, a clear photo of the nosebox wiring, and a completion screenshot showing green 'Verified' status for all five circuits. None of these requirements were met. The vendor's note is brief and lacks detail beyond identifying the missing Grote light and stating that parts have been ordered. No feedback was provided from the required category framework in a structured manner, and there is no indication the PCT app was opened or used.

Repair Summary: No repairs were completed on this work order. The technician identified a missing Grote light on the brake circuit and indicated that parts have been ordered, with an ETA to be provided later. There are no line items recorded — no parts, no labor charges — which is consistent with an incomplete repair. The alerting RED (Brake) circuit has not been restored to operational status as of the WO close date of March 16, 2026. This work order should not have been closed without either completing the repair or escalating to a pending/parts-on-order status.

Key Concerns: There are several significant concerns with this work order. First, the work order was marked complete despite no repair being made and parts still being on order — this is a premature closure that could mask an ongoing out-of-service lighting defect. Second, all submitted photos depict brake mechanical components (chambers, slack adjusters) rather than lighting components, suggesting the technician may have misunderstood the scope of the LCM-generated work order or submitted photos from the wrong inspection. Third, the PCT app was not used, meaning there is no verified confirmation of circuit status. Finally, the absence of any line items raises questions about whether a proper billable inspection even occurred. This WO should be flagged for follow-up to confirm parts receipt and repair completion, and the vendor should be reminded of photo and PCT app documentation requirements.
