Fuel tank leakage diagnosis module: Notes
NOTE:
The diagnosis module for tank leakage (DMTL) is country-dependent.
A system for leakage diagnosis is compulsory in the following countries: USA, Canada, Korea.
The tank-leak diagnosis can be used to determine the leak-tightness of the tank-ventilation system.
Tank leakage diagnosis allows a difference to be made between:
- Minor leak, greater than 1 mm
- Superfine leak, 0.5 mm to 1 mm
