The EVP-HN01 evacuation pump is activated on demand to support the evacuation of the brake booster. The EVP-HN01 can provide the necessary vacuum for the brake booster in a wide range of situations when the internal combustion engine is unable to do so, e.g. during the cold start/warm-up phase, at high altitudes or when using the air-conditioning system. The EVP-HN01 is installed parallel to the main combustion engine and evacuates filtered air via the brake booster and flexible pneumatic hoses.
Electrical contact between the EVP-HN01 and the ECU is made using a cable equipped with an engine compartment connector and attached to the vacuum pump.
