Leaking Checking

WARNING: This page is about a different variant/trim than selected.

The PCSV is closed and the system waits for a period to get stabilized pressure. During checking period (T2), the system measures the beginning and the end of the system pressure (DP_C, DP_D). The diagnosis value is the pressure difference corrected by the natural vapor generation (DP_B - DP_A) rate from the vapor generation check step.
