I have a brand new Honda Vezel (Japanese market only). It has this fanciful but useless and nuisance feature that shuts down the engine when I come to a stop and automatically restarts the engine once the foot is off the brake pedal. As a result, the air-conditioning compressor is driven from an another power source in addition to the serpentine belt from the engine. The AC is not as cool when the engine is not running. I think the thermostat is auto increased by a few degrees, maybe to save battery. Anyway, the engine will come on, even if foot is on the brakes, after a minute or so, presumably because the battery cannot take it anymore.
(I manually switch off this feature every time I start on a new journey.)
I now have a problem with the AC. The compressor runs for about 10 seconds and then cut off, at the usual thermostat setting of 26°C. I have to set it to more than 5°C down to achieve the previous cooling environment (ie before I discovered this problem).
I suspect the compressor may be operating in the mode when the engine is auto shut-off, ie the setting is compensated by n degrees. I want to do some investigations. How do I trigger an auto-engine shut down situation with the hood open and no one is in the driver's seat?
