How long should the air conditioner run to stabilize its cooling temperature during a "During" PMCS check?

The air conditioner should be run for 5 minutes during a "During" PMCS (Preventive Maintenance Checks and Services) check to stabilize its cooling temperature. This duration allows the system to reach an operational state, ensuring that it can effectively cool the interior of the vehicle. Running the unit for this amount of time helps to assess its performance by enabling the coolant to circulate adequately and giving the necessary time for temperature stabilization to occur. This is important for confirming that the air conditioner is functioning properly before concluding the maintenance check.

Shorter durations may not provide a full picture of the system's efficiency, while longer durations could be unnecessary for the purpose of quick diagnostics during the PMCS process. Thus, 5 minutes is the optimal time specified for this check.
