Yes, all external lighting sources, including low beams, high beams, fog lights, daytime running lights, reverse lights, and brake lights, are included in the mandatory power-on testing.

Absolutely. The extreme temperature fluctuations will significantly accelerate the aging of chassis rubber parts, oil seals, and interior plastics. For vehicles frequently dispatched across such latitudes, we will conduct fatigue resistance checks on chassis rubber parts that are twice as stringent as those for vehicles in temperate regions.

We will carefully check if the chassis number on the windshield, chassis, and door frame matches.
