No Fault Found

Sensor Verdict: The LCM system generated an alert on the RED (Brake) circuit for trailer GV2400210. Based on the vendor's findings — no fault found after continuity testing and wire harness inspection — the sensor alert cannot be definitively validated or dismissed. Confidence is low (35%) because the required PCT app verification was not completed, meaning the sensor's detection of a brake circuit anomaly was never formally cleared through the prescribed diagnostic process. The alert remains inconclusive from a protocol standpoint.

Photo Evidence: Thirteen photos were submitted with this work order. Photos 1, 2, and 5 show the ABS indicator panel on the trailer's rear corner post — notably, Photos 1 and 5 show the ABS amber lamp illuminated (indicating an active ABS fault), while Photos 2 and 5 also show a red light illuminated near the bottom of the post. Photos 3 and 8 show upper front corner marker lights (amber) glowing on what appears to be trailer GV2400210, confirming those lights are functional. Photo 4 shows a close-up of a brightly lit red light at the base of the rear post area. Photos 6 shows rear upper red marker/clearance lights on a different (dark-colored) trailer. Photos 7 and 12 show amber LED marker/identification lights functioning. Photos 9 and 10 show the full rear of the Amazon trailer (GV2400210) with red stop/tail/turn lights appearing functional. Photo 11 shows the trailer's VIN/data plate and a DOT inspection sticker. Photo 13 shows the full side/rear of the blue Amazon trailer GV2400210 in the yard. Critically, no nosebox wiring photo was provided, no Phillips Connect TechAssist app screenshot was submitted, and no systematic per-circuit illuminated photo set was included. The ABS warning lamp being illuminated in multiple photos is a notable concern that was not addressed in the repair notes.

Vendor Compliance: The vendor did not follow the LCM troubleshooting procedure as instructed. The procedure explicitly required use of the Phillips Connect TechAssist app, photographs of each light illuminated, a clear nosebox wiring photo, and a TechAssist completion screenshot showing green 'Verified' status beside each of the 5 circuits. None of these requirements were met. The vendor instead performed a manual continuity test and visual walk-around, which, while a reasonable basic diagnostic step, does not satisfy the LCM-specific protocol. The feedback category used ('no defect found') is listed as valid only when confirmed with PCT — which it was not. This represents a significant compliance gap.

Repair Summary: No repairs were made on this work order. The vendor concluded the 7-way nose box or wiring harness showed no cuts, damage, or continuity faults. The single line item listed is a placeholder ('Details to Follow'), which suggests incomplete documentation. Since no defect was confirmed and no parts were replaced, there is nothing to assess regarding compliant brand usage. The alerting RED (Brake) circuit was neither confirmed repaired nor formally cleared via PCT verification.

Key Concerns: Several concerns are flagged for this work order: (1) The ABS amber warning light is visibly illuminated in multiple submitted photos, suggesting an active ABS fault on this trailer that was not mentioned or addressed in the vendor notes — this is a separate but significant safety concern. (2) The vendor did not use the PCT TechAssist app as required, meaning the LCM alert on the RED circuit was never formally resolved through the correct process. (3) The lone line item is a placeholder with no details, indicating incomplete documentation. (4) No nosebox photo was provided despite it being a required deliverable. (5) The work order includes location updates suggesting the trailer was moved off-site and back, which may indicate the trailer was dispatched or repositioned without the fault being properly resolved. A revisit with full PCT compliance is strongly recommended.
